    BACKGROUND: Non-alcoholic steatohepatitis (NASH) is a progressive subtype of non-alcoholic fatty liver disease (NAFLD) that is closely related to cardiovascular disease (CVD). Nitric oxide (NO) plays a critical role in the control of various biological processes. Dysfunction of the NO signaling pathway is associated with various diseases such as atherosclerosis, vascular inflammatory disease, and diabetes. Recently, it has been reported that NO is related to lipid and cholesterol metabolism. Chronic NO synthase (NOS) inhibition accelerates NAFLD by increasing hepatic lipid deposition. However, the detailed relationship between NO and abnormal lipid and cholesterol metabolism in NAFLD/NASH has not been completely explained. We aimed to determine the effects of NOS inhibition by N omega-nitro-L-arginine methyl ester hydrochloride (L-NAME), a NOS inhibitor, on NASH and CVD via lipid and cholesterol metabolism. METHODS: Stroke-prone spontaneously hypertensive rats were fed a high-fat and high-cholesterol diet for 8 weeks and administered L-NAME for the last 2 weeks. Following blood and tissue sampling, biochemical analysis, histopathological staining, quantitative RT-PCR analysis, and western blotting were performed. RESULTS: L-NAME markedly increased hepatic triglyceride (TG) and cholesterol levels by promoting TG synthesis and cholesterol absorption from the diet. L-NAME increased the mRNA levels of inflammatory markers and fibrotic areas in the liver. Cholesterol secretion from the liver was promoted in rats administered L-NAME, which increased serum cholesterol. L-NAME significantly increased the level of oxidative stress marker and lipid deposition in the arteries. CONCLUSIONS: NOS inhibition simultaneously aggravates NASH and atherosclerosis via hepatic lipid and cholesterol metabolism.

  • A high-fat/high-cholesterol diet, but not high-cholesterol alone, increases free cholesterol and apoE-rich HDL serum levels in rats and upregulates hepatic ABCA1 expression. Reviewed International journal

    A high-fat/high-cholesterol (HFC) diet, but not a high-cholesterol (HC) diet, is known to induce elevated serum apolipoprotein E (apoE)-rich high-density lipoprotein (HDL) levels in animal models. However, the exact mechanisms by which the combination of dietary fat and cholesterol induces apoE-rich HDL production is not well understood. Here, we investigated the effects of dietary fat and cholesterol on serum lipoprotein profiles and hepatic mRNA expression that are associated with HDL production, cholesterol transport, and bile acid metabolism. Male Sprague-Dawley rats were fed HFC, HC, high-fat, or control diets and then evaluated. The HFC diet induced significant increases in hepatic free-cholesterol accumulation (1.4-fold, p < 0.01) and serum apoE-rich HDL cholesterol (8.7-fold, p < 0.001) levels compared with the HC diet. The apoE-rich HDL induced by the HFC diet was remarkably rich in free cholesterol. Liver gene-expression was mostly similar between the HC and HFC diet groups. However, there was a significant increase of ATP-binding cassette transporter A1 (ABCA1) levels in the HFC group compared to the HC group for both mRNA (1.9-fold, p < 0.001) and protein (6.6-fold, p < 0.01). These results suggest that an increase in apoE-rich HDL induced by dietary fat and cholesterol may be involved in cholesterol efflux from the liver through increased ABCA1-mediated free-cholesterol efflux.

    Osteoarthritis is a progressive disease characterized by cartilage destruction in the joints. Matrix metalloproteinases (MMPs) and a disintegrin and metalloproteinase with thrombospondin motifs (ADAMTSs) play key roles in osteoarthritis progression. In this study, we screened a chemical compound library to identify new drug candidates that target MMP and ADAMTS using a cytokine-stimulated OUMS-27 chondrosarcoma cells. By screening PCR-based mRNA expression, we selected 2-(8-methoxy-2-methyl-4-oxoquinolin-1(4H)-yl)-N-(3-methoxyphenyl) acetamide as a potential candidate. We found that 2-(8-methoxy-2-methyl-4-oxoquinolin-1(4H)-yl)-N-(3-methoxyphenyl) acetamide attenuated IL-1β-induced MMP13 mRNA expression in a dose-dependent manner, without causing serious cytotoxicity. Signaling pathway analysis revealed that 2-(8-methoxy-2-methyl-4-oxoquinolin-1(4H)-yl)-N-(3-methoxyphenyl) acetamide attenuated ERK- and p-38-phosphorylation as well as JNK phosphorylation. We then examined the additive effect of 2-(8-methoxy-2-methyl-4-oxoquinolin-1(4H)-yl)-N-(3-methoxyphenyl) acetamide in combination with low-dose betamethasone on IL-1β-stimulated cells. Combined treatment with 2-(8-methoxy-2-methyl-4-oxoquinolin-1(4H)-yl)-N-(3-methoxyphenyl) acetamide and betamethasone significantly attenuated MMP13 and ADAMTS9 mRNA expression. In conclusion, we identified a potential compound of interest that may help attenuate matrix-degrading enzymes in the early osteoarthritis-affected joints.

    Angiogenesis and lymphangiogenesis play roles in malignant tumor progression, dissemination, and metastasis. ADAMTS1, a member of the matrix metalloproteinase family, is known to inhibit angiogenesis. Recombinant ADAMTS1 was shown to strongly inhibit angiogenesis. We investigated whether ADAMTS1 inhibited lymphangiogenesis in the present study. We examined cell proliferation and cell migration in normal human dermal lymphatic microvascular endothelial cells (HMVEC-dLy) transduced with or without adenoviral human ADAMTS1 gene therapy. We then examined the VEGFC/VEGFR3 signal transduction pathway in ADAMTS1-transduced HMVEC-dLy. Cell proliferation and tube formation in Matrigel were significantly lower with transduced ADAMTS1 than with control (non-transduced HMVEC-dLy). The phosphorylation of VEGFR3 was also attenuated by ADAMTS1 gene therapy in HMVEC-dLy. Immunoprecipitation assays revealed that ADAMTS1 formed a complex with VEGFC. Our results demonstrated that ADAMTS1 inhibited lymphangiogenesis in vitro. The data highlight the new function of ADAMTS1 in the regulation of lymphangiogenesis and the therapeutic potential of ADAMTS1 in cancer therapy.

    Characteristically, most solid tumors exhibit an increased tumor interstitial fluid pressure (TIFP) that directly contributes to the lowered uptake of macromolecular therapeutics into the tumor interstitium. Abnormalities in the tumor-associated lymph vessels are a central brick in the development and prolonged sustaining of an increased TIFP. In the current study, vascular endothelial growth factor C (VEGF-C) was used to enhance tumor-associated lymphangiogenesis as a new mechanism to actively reduce the TIFP by increased lymphatic drainage of the tumor tissue. Human A431 epidermoid vulva carcinoma cells were inoculated in NMRI nu/nu mice to generate a xenograft mouse model. Seven days after tumor cell injection, VEGF-C was peritumorally injected to induce lymphangiogenesis. Tumor growth and TIFP was lowered significantly over time in VEGF-C-treated tumors in comparison to control or VEGF-A-treated animals. These data demonstrate for the first time that actively induced lymphangiogenesis can lower the TIFP in a xenograft tumor model and apparently reduce tumor growth. This model represents a novel approach to modulate biomechanical properties of the tumor interstitium enabling a lowering of TIFP in vivo.

    Fractional flow reserve (FFR) is the gold standard for assessing the physiological significance of coronary stenosis. We examined the potential correlation between digitally measured coronary cross-sectional area stenosis using coronary computed tomography (CT) angiography and FFR. We analyzed data of 32 consecutive patients with stenoses who underwent invasive FFR determination. The cross-sectional area was assessed using 128-slice coronary detector-based spectral CT angiography. Power analysis revealed that the sample size enabled the detection of an area under the receiver operating characteristic (ROC) curve (AUC) of 0.90. FFR ≤ 0.8 and > 0.8 were defined as FFR-positive and FFR-negative, respectively. Intra- and interobserver differences were negligible. Percentage cross-sectional area stenosis was calculated as 100 × (A-B)/A, where A is the cross-sectional area at non-stenotic pre-stenotic segment and B is the cross-sectional area of the most severe stenotic lesion. AUC indicated that percentage cross-sectional area stenosis effectively discriminated between FFR-positive and FFR-negative cases, yielding a sensitivity of 0.882 and specificity of 0.933 at a cutoff of 50% area reduction, with an AUC of 0.976. Lesions with less than 45% cross-sectional area stenosis on coronary CT angiography were not FFR-positive. When ROC analysis was conducted for lesion characteristics, AUC did not significantly improve. In conclusion, the percent coronary cross-sectional area stenosis measured using coronary CT angiography distinguished between FFR-positive and FFR-negative lesions with high accuracy. The severity of coronary cross-sectional area stenosis determined using CT angiography is clinically useful for predicting FFR.

    BACKGROUND: The effectiveness of a novel diamond tip temperature-controlled ablation (DTA) catheter for left atrial posterior wall isolation (LAPWI) remains unclear. OBJECTIVE: This study evaluated the efficacy and safety of the DTA catheter for LAPWI under electrogram (EGM) guidance. METHODS: This single-center observational study compared the first-pass LAPWI success rate among three groups: DTA with EGM guidance (n = 82), conventional irrigation catheter with EGM guidance (Irri with EGM guidance; n = 92), and Irri without EGM guidance (n = 93), using fixed energy parameters (30 W, 15-20 s). RESULTS: DTA with EGM guidance had a significantly higher incidence of first-pass LAPWI success (93%, 76/82) than that of Irri without EGM guidance (54%; 50/93) (p < 0.001) and had a success rate comparable to that of the Irri with EGM guidance (97%; 89/92). Post hoc Bonferroni analysis demonstrated that the DTA with EGM guidance group had a significantly shorter radiofrequency-energy delivery duration (158 ± 63 s) than that of the Irri with EGM guidance group (229 ± 131 s; p < 0.0001) and the Irri without EGM guidance group (243 ± 185 s; p < 0.001). The DTA with EGM guidance group had a higher average RF power (45.1 ± 5.6 W) than the Irri with (31.2 ± 2.2 W; p < 0.0001) and without EGM guidance groups (28.0 ± 8.9 W; p < 0.001). No significant complications were observed. CONCLUSIONS: The novel DTA catheter with EGM guidance achieved a high first-pass LAPWI success rate. The novel DTA catheter with short energy delivery and high average radiofrequency (RF) energy delivery under EGM guidance can be effectively applied in LAPWI.

    Chondrocytes are responsible for the production of extracellular matrix (ECM) components such as collagen type II alpha-1 (COL2A1) and aggrecan, which are loosely distributed in articular cartilage. Chondrocyte dysfunction has been implicated in the pathogenesis of rheumatic diseases such as osteoarthritis (OA) and rheumatoid arthritis (RA). With age, advanced glycation end products (AGEs) accumulate in all tissues and body fluids, including cartilage and synovial fluid, causing and accelerating pathological changes associated with chronic diseases such as OA. Glycolaldehyde-derived AGE (AGE3), which is toxic to a variety of cell types, have a stronger effect on cartilage compared with other AGEs. To understand the long-term effects of AGE3 on cartilage, we stimulated a human chondrosarcoma cell line (OUMS-27), which exhibits a chondrocytic phenotype, with 10 μg/ml AGE3 for 4 weeks. As a result, the expressions of COL2A1 and aggrecan were significantly downregulated in the OUMS-27 cells without inducing cell death, but the expressions of proteases that play an important role in cartilage destruction were not affected. Inhibition of the receptor for advanced glycation end products (RAGE) suppressed the AGE3-induced reduction in cartilage component production, suggesting the involvement of RAGE in the action of AGE3.

    Objective Identifying patients at high risk of steatotic liver disease (SLD) is crucial. The liver fibrosis stage is the most reliable marker of liver-related mortality. However, noninvasive risk stratification methods remain controversial. Therefore, we analyzed the risk of liver-related events in patients who underwent a liver biopsy for metabolic dysfunction-associated steatotic liver disease (MASLD) or cryptogenic SLD at our hospital. Methods We retrospectively reviewed the clinical course of the patients to identify the occurrence of liver-related events. Patients This study included 146 patients diagnosed with SLD through a liver biopsy. Results Liver-related events occurred in 20 patients and were more frequent in those with advanced fibrosis than in those without advanced fibrosis. However, patients with advanced steatosis exhibit reduced disease progression. Patients with obesity and/or diabetes complications had a lower stage of fibrosis and better prognosis than the others. The non-invasive fibrosis-4 (FIB-4) index and non-alcoholic fatty liver disease (NAFLD) prognosis-related "NAFLD outcomes score (NOS)" effectively differentiated patients with disease progression. Standard laboratory data analyses revealed that high total bilirubin and low albumin levels were risk factors. A multivariate analysis with significant factors other than NOS score revealed that the absence of obesity and/or diabetes complications, a high FIB-4 index, and a high total bilirubin level were independent factors for liver-related events. Conclusion A high NOS score, absence of obesity and/or diabetes complications, a high FIB-4 index, and high total bilirubin levels are risk factors for disease progression. Patients with lean phenotypes or non-diabetic SLD should also be assessed using noninvasive markers to determine their risks and potential outcomes.

    BackgroundMethods for measuring activated clotting time (ACT) are not yet standardized.ObjectivesTo adjust and compare values between two measurement systems and to optimize ACT during atrial fibrillation (AF) ablation.MethodsTwo systems were compared: electromagnetic detection using a rotating tube (EM system; Hemochron Response) and photo-optical detection using a cartridge immersed in blood (PO system; ACT CA-300TM).ResultsACT was measured simultaneously in 124 instances in 53 patients before and during AF ablations using both methods. A linear regression analysis showed ACT (EM system) = 1.19 × ACT (PO system) + 9.03 (p < .001, r = 0.90). Bland-Altman plots indicated an average difference of 50 s between the two systems. In 3364 ACT measurements from 1161 ablations, the EM system recorded a mean ACT of 320 ± 44 s (range 156-487 s). Estimating the target range as mean ± 1 SD range, the EM system's range was 275-365 s, in 5-s increments. The pre-ablation ACT measured on the EM system was 143 ± 28 s (115-170 s). Cardiac tamponade occurred in 4 out of 2085 ablations (0.19%) over 5 years, with ACT values ranging from 330 to 391 s on the EM system. Based on these findings, the estimated optimal ACT range for the PO system was adjusted to 225-300 s to align with the EM system's range of 275-365 s.ConclusionsACT target ranges should be system-specific, and direct extrapolation between devices is not recommended. Adjustment is clinically necessary when switching systems.

    INTRODUCTION: Tumor necrosis factor-α (TNF-α)-induced angiogenesis plays a critical role in tumor progression and metastasis, making it an important therapeutic target in cancer treatment. Suppressing angiogenesis can effectively limit tumor growth and metastasis. However, despite advancements in understanding angiogenic pathways, effective strategies to inhibit TNF-α-mediated angiogenesis remain limited. METHODS: This study investigates the antiangiogenic effects of histidine-rich glycoprotein (HRG), a multifunctional plasma protein with potent antiangiogenic properties, on TNF-α-stimulated human endothelial cells (EA.hy926). Tube formation assays were performed to assess angiogenesis, and gene/protein expression analyses were conducted to evaluate HRG's effects on integrins αV and β8. The role of nuclear factor erythroid 2-related factor 2 (NRF2) in HRG-mediated antiangiogenic activity was also examined through nuclear translocation assays and NRF2 activation studies. RESULTS: At physiological concentrations, HRG effectively suppressed TNF-α-induced tube formation in vitro and downregulated TNF-α-induced expression of integrins αV and β8 at both the mRNA and protein levels. HRG treatment promoted NRF2 nuclear translocation in a time-dependent manner. Furthermore, activation of NRF2 significantly reduced TNF-α-induced tube formation and integrin expression, suggesting that NRF2 plays a key role in HRG-mediated antiangiogenic effects. DISCUSSION AND CONCLUSION: Our findings indicate that HRG suppresses TNF-α-induced angiogenesis by promoting NRF2 nuclear translocation and transcriptional activation, which in turn inhibits integrin αV and β8 expression. Given the essential role of angiogenesis in tumor progression, HRG's ability to regulate this process presents a promising therapeutic strategy for cancer treatment.

    BACKGROUND: Maintaining an adequate temperature at the target site is essential for effective ablation. We hypothesized that a tissue temperature-controlled (T-Con) catheter for cavotricuspid isthmus (CTI) ablation could improve the procedural ablation parameters. PURPOSE: To evaluate the efficacy and safety of the T-Con (DiamondTemp™) catheter for CTI ablation compared with non-irrigation (Non-Irri) and irrigation (Irri) catheters. METHODS: We analyzed 150 patients who underwent prophylactic CTI ablation combined with pulmonary vein isolation. The Non-Irri, Irri, and T-Con catheter groups comprised 50 patients each, and the ablation procedural parameters and complications were compared between these groups. RESULTS: There were no significant differences in clinical background characteristics among the three groups. The Kruskal-Wallis and post hoc tests demonstrated that the T-Con group showed the lowest total radiofrequency energy delivery time among the three groups (median [25 and 75 percentiles]: 340 [209, 357], 147 [100, 199], and 83 [61, 109] s, respectively in the Non-Irri, Irri, and T-Con groups; T-Con versus Non-Irri, p < .01; T-Con versus Irri, p < .01). The total procedural time and acute reconnection rate in the T-Con group (264 s and 4%, respectively) were lower than those in the Non-Irri group (438 s and 24%) but were similar to those in the Irri group (268 s and 6%). No significant complications were observed in any group. CONCLUSIONS: The T-Con catheter achieved a short energy delivery time and a low acute reconnection rate, indicating its potential as an alternative catheter for CTI ablation.

    The liver X receptor (LXR) can enhance cholesterol transporters, which could remove excess cholesterol from foam cells in atheromas. LXR has two subtypes: LXRα, which aggravates hepatic lipid accumulation, and LXRβ, which does not. In 2018, ouabagenin (OBG) was reported as a potential LXRβ-specific agonist. We aimed to examine whether OBG specifically affects LXRβ in nonalcoholic steatohepatitis (NASH); it did not aggravate hepatic steatosis and can suppress the development of atherosclerosis. SHRSP5/Dmcr rats fed a high-fat and high-cholesterol diet were divided into four groups as follows: (I) L-NAME group, (II) L-NAME/OBG group, (III) OBG (-) group, and (IV) OBG (+) group. All groups’ rats were intraperitoneally administered L-NAME. The L-NAME/OBG groups’ rats were intraperitoneally administered OBG and L-NAME simultaneously. After L-NAME administration, the OBG (+) groups’ rats were administered OBG, while the OBG (-) groups’ rats were not. Although all rats developed NASH, OBG did not exacerbate steatosis (L-NAME/OBG and OBG (+) groups). In addition, endothelial cells were protected in the L-NAME/OBG group and foam cells in the atheroma were reduced in the OBG (+) group. OBG is an LXRβ-specific agonist and has a potential therapeutic effect on atherosclerosis without developing lipid accumulation in the liver.

    BACKGROUND: Secondary sarcopenia develops as a result of a bedridden state and illnesses, such as cachexia, liver disease, and diabetes. However, there is a lack of animal models to investigate the underlying mechanisms and potential treatments for secondary sarcopenia. Recently, secondary sarcopenia has been associated with the prognosis of nonalcoholic steatohepatitis. This study aimed to investigate whether stroke-prone spontaneously hypertensive rat 5 (SHRSP5/Dmcr) which developed severe nonalcoholic steatohepatitis by a high-fat and high-cholesterol (HFC; containing 2% cholic acid) diet is a useful model of secondary sarcopenia. METHODS: SHRSP5/Dmcr rats were divided into 6 groups fed with a Stroke-Prone (SP: normal chow) or HFC diets for different periods (4, 12, and 20 weeks), and WKY/Izm rats were divided into 2 groups fed an SP or HFC diet. Body weight, food intake, and muscle force were measured weekly for all rats. After the end of the diet period, skeletal muscle strength evoked by electrical stimulation was recorded, blood was collected, and organ weight was measured. The sera were used for biochemical analysis and the organs were used for histopathological analysis. RESULTS: SHRSP5/Dmcr rats fed an HFC diet developed nonalcoholic steatohepatitis, and their skeletal muscles, especially fast muscles, showed atrophy, indicating that muscle atrophy is aggravated by the progression of nonalcoholic steatohepatitis. In contrast, WKY/Izm rats fed an HFC diet did not exhibit sarcopenia. CONCLUSIONS: This study suggests that SHRSP5/Dmcr rats could be a useful novel model for investigate the mechanism of secondary sarcopenia disorder associated with nonalcoholic steatohepatitis.

    BACKGROUND: The metabolic state of pulmonary artery smooth muscle cells (PASMCs) from patients with pulmonary arterial hypertension (PAH) is not well understood. In this study, we examined the balance between glycolysis and mitochondrial respiration in non-PAH-PASMCs and PAH-PASMCs under normoxia and hypoxia. METHODS: We investigated the enzymes involved in glycolysis and mitochondrial respiration, and studied the two major energy-yielding pathways (glycolysis and mitochondrial respiration) by measuring extracellular acidification rate (ECAR) and cellular oxygen consumption rate (OCR) using the Seahorse extracellular flux technology. RESULTS: Under both normoxia and hypoxia, the mRNA and protein levels of pyruvate dehydrogenase kinase 1 and pyruvate dehydrogenase were increased in PAH-PASMCs compared with non-PAH-PASMCs. The mRNA and protein levels of lactate dehydrogenase, as well as the intracellular lactate concentration, were also increased in PAH-PASMCs compared with non-PAH-PASMCs under normoxia. However, these were not significantly increased in PAH-PASMCs compared with non-PAH-PASMCs under hypoxia. Under normoxia, ATP production was significantly lower in PAH-PASMCs (59 ± 5 pmol/min) than in non-PAH-PASMCs (70 ± 10 pmol/min). On the other hand, ATP production was significantly higher in PAH-PASMCs (31 ± 5 pmol/min) than in non-PAH-PASMCs (14 ± 3 pmol/min) under hypoxia. CONCLUSIONS: There is an underlying change in the metabolic strategy to generate ATP production under the challenge of hypoxia.

    Non-alcoholic steatohepatitis (NASH) is a progressive form of non-alcoholic fatty liver disease (NAFLD) that causes cirrhosis and hepatocellular carcinoma. Iron is an essential trace element in the body; however, excess iron can cause tissue damage and dysfunction. Iron overload is often observed in patients with NASH, and the amount of iron accumulated in the liver positively correlates with the histological severity of NASH. Ferroptosis, a novel form of iron-dependent cell death, is caused by the accumulation of lipid peroxidation and oxidative stress and is related to NASH. In addition, ferroptosis is closely related to autophagy, an intracellular self-degradation process. Although autophagy has many beneficial effects, it may also be harmful to the organism, for example, inducing ferroptosis. It is unclear whether iron overload aggravates NASH via autophagy. The aim of this research is to determine the mechanism by which iron overload induces ferroptosis via autophagy and aggravates NASH. Stroke-prone spontaneously hypertensive rats (SHRSP5/Dmcr) were divided into two groups and fed a high-fat and high-cholesterol (HFC) diet for eight weeks. Iron dextran was administered to the Fe group in addition to the HFC diet. Blood analysis, histological staining, calcineurin activity assay, quantitative reverse transcription polymerase chain reaction (RT-PCR), immunofluorescence staining, and electron microscopy were performed. The results showed that iron overload promoted autophagy via nuclear translocation of transcription factor EB (TFEB) and induced ferritinophagy, which is the autophagic degradation of ferritin. In addition, the HFC diet induced lipophagy, the autophagic degradation of lipid droplets. The Fe group also exhibited promoted ferroptosis and aggravated hepatic inflammation and fibrosis. In conclusion, iron overload accelerates ferritinophagy and lipophagy, aggravating NASH pathology via ferroptosis. These findings indicate the therapeutic potential of inhibiting autophagy and ferroptosis for treating NASH.

    BACKGROUND: Xanthine oxidase (XO) generates reactive oxygen species during uric acid production. Therefore, XO inhibitors, which suppress oxidative stress, may effectively treat non-alcoholic steatohepatitis (NASH) and atherosclerosis via uric acid reduction. In this study, we examined the antioxidant effect of the XO inhibitor febuxostat on NASH and atherosclerosis in stroke-prone spontaneously hypertensive 5 (SHRSP5/Dmcr) rats. METHODS: SHRSP5/Dmcr rats were divided into three groups: SHRSP5/Dmcr + high-fat and high-cholesterol (HFC) diet [control group, n = 5], SHRSP5/Dmcr + HFC diet + 10% fructose (40 ml/day) [fructose group, n = 5], and SHRSP5/Dmcr + HFC diet + 10% fructose (40 ml/day) + febuxostat (1.0 mg/kg/day) [febuxostat group, n = 5]. Glucose and insulin resistance, blood biochemistry, histopathological staining, endothelial function, and oxidative stress markers were evaluated. RESULTS: Febuxostat reduced the plasma uric acid levels. Oxidative stress-related genes were downregulated, whereas antioxidant factor-related genes were upregulated in the febuxostat group compared with those in the fructose group. Febuxostat also ameliorated inflammation, fibrosis, and lipid accumulation in the liver. Mesenteric lipid deposition decreased in the arteries, and aortic endothelial function improved in the febuxostat group. CONCLUSIONS: Overall, the XO inhibitor febuxostat exerted protective effects against NASH and atherosclerosis in SHRSP5/Dmcr rats.

    Abstract

    Amyloid-β (Aβ) deposition in the brain parenchyma is one of the pathological hallmarks of Alzheimer disease (AD). We have previously identified amyloid precursor protein (APP)669-711 (a.k.a. Aβ(-3)-40) in human plasma using immunoprecipitation combined with matrix-assisted laser desorption ionization time-of-flight mass spectrometry (IP-MALDI-MS). Furthermore, we found that the level of a composite biomarker, i.e., a combination of APP669-711/Aβ1-42 ratio and Aβ1-40/Aβ1-42 ratio in human plasma, correlates with the amyloid PET status of AD patients. However, the production mechanism of APP669-711 has remained unclear. Using in vitro and in vivo assays, we identified A Disintegrin and Metalloproteinase with a Thrombospondin type 1 motif, type 4 (ADAMTS4) as a responsible enzyme for APP669-711 production. ADAMTS4 cleaves APP directly to generate the C-terminal stub c102, which is subsequently proteolyzed by γ-secretase to release APP669-711. Genetic knockout of ADAMTS4 reduced the production of endogenous APP669-711 by 30% to 40% in cultured cells as well as mouse plasma, irrespectively of Aβ levels. Finally, we found that the endogenous murine APP669-711/Aβ1-42 ratio was increased in aged AD model mice, which shows Aβ deposition as observed in human patients. These data suggest that ADAMTS4 is involved in the production of APP669-711, and a plasma biomarker determined by IP-MALDI-MS can be used to estimate the level of Aβ deposition in the brain of mouse models.

    The SHRSP5/Dmcr is a useful animal model for the development of nonalcoholic steatohepatitis (NASH) pathology when fed a high-fat, high-cholesterol diet, and further drug interventions can lead to concomitant cardiovascular disease. While SHRSP5/Dmcr rats have been used for basic research related to NASH, details of their bile acid metabolism in this condition are unknown. In this study, we aimed to clarify the changes in the serum bile acid (BA) fractions associated with NASH and found that glycine-conjugated and unconjugated bile acid increased with worsening NASH and cardiovascular disease while taurine-conjugated BA relatively decreased.

    While androgen is considered a pivotal regulator of sexually dimorphic development, it remains unclear how it orchestrates the differentiation of reproductive organs. Using external genitalia development as a model, we showed that androgen, through the transcription factor MafB, induced cell migration by remodeling the local extracellular matrix (ECM), leading to increased cell contractility and focal adhesion assembly. Furthermore, we identified the matrix metalloproteinase Mmp11 as a MafB target gene under androgen signaling. MMP11 remodels the local ECM environment by degrading Collagen VI (ColVI). The reduction of ColVI led to the fibrillar deposition of fibronectin in the MafB-expressing bilateral mesenchyme both in vivo and ex vivo. The ECM remodeling and development of migratory cell characteristics were lost in the MafB loss-of-function mice. These results demonstrate the requirement of mesenchymal-derived androgen signaling on ECM-dependent cell migration, providing insights into the regulatory cellular mechanisms underlying androgen-driven sexual differentiation.

    The mechanomyogram (MMG) is a signal measured by various vibration sensors for slight vibrations induced by muscle contraction, and it reflects the muscle force during electrically induced-contraction or until 60%-70% maximum voluntary contraction, so the MMG is considered an alternative and novel measurement tool for muscle strength. We simultaneously measured the MMG and muscle force in the gastrocnemius (GC), vastus intermedius (VI), and soleus (SOL) muscles of rats. The muscle force was measured by attaching a hook to the tendon using a load cell, and the MMG was measured using a charged-coupled device-type displacement sensor at the middle of the target muscle. The MMG-twitch waveform was very similar to that of the muscle force; however, the half relaxation time and relaxation time (10%), which are relaxation parameters, were prolonged compared to those of the muscle force. The MMG amplitude correlated with the muscle force. Since stimulation frequencies that are necessary to evoke tetanic progression have a significant correlation with the twitch parameter, there is a close relationship between twitch and tetanus in the MMG signal. Therefore, we suggest that the MMG, which is electrically induced and detected by a laser displacement sensor, may be an alternative tool for measuring muscle strength.

    Damage-Associated Molecular Patterns(DAMPs)は細胞ストレスに伴い放出される内因性免疫応答調節因子である。過剰なDAMPsの生成は、炎症の遷延化や増悪を促す。慢性炎症性疾患の病変部位では、血管新生を伴うリモデリングが誘導され、病態増悪の本態として考えられている。その機序として、DAMPsと炎症性メディエーターの相互作用によるマクロファージ(MΦ)の過剰な活性化が関与することが示唆されている。本研究では、慢性炎症性病態であるアレルギー性炎症に焦点をあて、その病態形成に関与するDAMPsのInterleukin-33(IL-33)と炎症性メディエーターのヒスタミンによる血管新生に対する影響について解析を行った。
    ヒト血管内皮細胞株EA.hy926細胞を用いたin vitro実験系において、ヒスタミンはIL-33の発現量を増加させることを確認した。ヒスタミンによるIL-33発現量の増加作用は、ヒスタミンH1受容体が関与することを明らかにした。
    さらに、マトリゲルを用いたin vitro血管新生実験モデルにおいて、ヒスタミンはヒスタミンH1受容体を介して管腔形成を促進させることを見出した。ヒスタミンにより血管内皮増殖因子(vascular endothelial growth factor、VEGF)の発現上昇が認められたが、ヒスタミンによる管腔形成促進作用はVEGF受容体の阻害剤では抑制されなかった。したがって、ヒスタミンはVEGFとは異なる機序を介して血管新生を促進する可能性が示唆された。

    細胞外分泌小胞は細胞から分泌される30-100nmのエクソソームなどを含む微小な小胞である。細胞外分泌小胞の内部にはmicroRNAなどが含まれている。最近の研究によって、細胞外分泌小胞が、分泌された元の細胞から、小胞の取り込まれた別の細胞へ小胞内に含まれる物質などを送達し、取り込まれた細胞に影響を及ぼす、つまり細胞間情報伝達機構を担っていることが明らかとなってきた。
    細胞外分泌小胞の作用メカニズムとして細胞に取り込まれた細胞外分泌小胞の内部に含まれているmicroRNAが取り込まれた細胞内で標的RNAに作用すると考えられるなど、その疾患における役割が注目を集めている。
    本研究では、細胞外分泌小胞の表面分子と、取り込む細胞という二つの因子に着目して、それぞれがどのように取り込み機構にかかわっているのかを明らかにする。さらに、組織由来細胞外分泌小胞に着目し、その性質・情報伝達について明らかにすることを目的とする。
    本年度は赤色蛍光標識した細胞外分泌小胞を恒常的に発現するHEK293細胞が軟骨細胞または滑膜細胞と直接接することなく、エクソソームなどは通過できる特殊な水平型分離共培養実験系を用いた。水平型分離共培養装置を用いて検討したところ、HEK293細胞から分泌された細胞外分泌小胞が軟骨細胞および滑膜細胞へそれぞれ取り込まれることが明らかとなった。さらに、取り込み機序に関わる表面分子に着目した。この分子に対する特異的抗体を用いた検討により軟骨細胞および滑膜細胞への取り込みを検討した。

    We analyzed the expression regions of CCR2 and osteopontin (OPN) using NASH rat model liver tissues, to elucidate the molecular mechanism of liver fibrosis in nonalcoholic steatohepatitis (NASH). In this study, the OPN expression region expanded as the increased number of weeks of HFC diet feeding, but its expression was observed only in the macrophages in the early stage of fibrosis. Moreover, as liver fibrosis progressed, OPN-positive region expanded and CCR2 was attenuated in the macrophage aggregation. Therefore, in the early stage of fibrosis, the macrophage aggregation was mainly composed CCR2-positive macrophages and gradually became OPN-positive macrophages. It became clear that a dynamic change of replacement occurs. This result suggests that there are different groups of OPN-positive and CCR2-positive macrophages and they may be closely related.

    我々は変形性関節症(OA)患者の関節液中で上昇し、軟骨マトリックスを分解するマトリックス分解酵素の発現を誘導する炎症性サイトカイン(Interleukin-1β(IL-1β))が軟骨細胞の産生するエクソソームでのCD9(テトラスパニン29)発現を増加していることをwestern分析により明らかにした。患者滑液由来エクソソームにおいてもCD9の発現を確認している。このCD9は細胞接着とシグナル伝達を介して、炎症等に関連すると考えられており、OA患者滑膜で発現が上昇すること(Bull Hosp Jt Dis. 2005;63(1-2):63-9)、CD9ノックアウト(KO)マウスを用いたOAモデルの一部では軟骨損傷が少ないなどの報告(Biomed Res.2016; 37(5):283-291)もありOAへの関与が示唆される。更に、炎症性サイトカイン刺激により軟骨細胞自身のCD9発現を誘導することをRT-PCR、細胞免疫染色で明らかにした。
    エクソソームを蛍光標識することにより軟骨細胞へのエクソソームの取り込みを確認した。ダイナミン阻害剤を用いるとエクソソームの取り込みがほとんど無くなったことから、エクソソーム取り込みの主たる経路はクラスリンを介したエンドサイトーシスであることを明らかにした。

    We showed that serum HDL-cholesterol levels decreased in rats fed ethanol and their HDL changed to free cholesterol-rich particles. The quantitative and qualitative changes in HDL may be associated with the increased mRNA expression of scavenger receptor class B type I, which functions as an HDL receptor in the liver. It was suggested that the increase in SR-BI expression by ethanol intake may work to suppress atherosclerosis through activation of the reverse cholesterol transport system.

    In Japan, patients with Hansen‘s disease were forcibly detained, followed by lifetime isolation. To prevent the same mistakes, it is necessary to establish medical ethics for Hansen‘s disease. This project primarily constructed a curriculum on "Hansen‘s disease and Medical Ethics" (for medical students), and on “Hansen‘s disease and Human Dignity” (for elementary to university students), which initiated a series of on-site lectures. Subsequent qualitative analysis of survival narratives elucidated the ethical issues of lost sight due to clinical trials, the structure of spiritual pain from lifelong isolation, perceptual disorders, and their perception of the COVID-19 pandemic. Our published book, "The Beauty of Nature and Prayer in Sanatoriums," and the digital teaching materials, convey the wisdom gained through a life of hardship. Finally, the Society for the Ethics of Hansen‘s disease was established, and the journal “Hansen‘s disease and Human Dignity” was published.

    There is no definite early diagnosis of osteoarthritis. Can liquid biopsy be a new early diagnosis for osteoarthritis?
    To answer this important question, rat anterior cruciate ligament and the medial collateral ligament of the rat knee joint were dissected and the medial meniscus was taken, and the osteoarthritis surgical model was prepared. The joint fluid and peripheral blood were collected over time. The vesicle component containing exosomes was purified from the sample and the particle size was measured. Next, RNA components contained in exosomes were quantified. From the series of results, it was considered appropriate to aim at liquid biopsy with blood rather than joint fluid at the early stage of osteoarthritis. Furthermore, the analysis of RNA in exosomes in blood revealed that a highly sensitive measurement system is required.

    Osteoarthritis (OA) is the most common bone and joint disease in the field of orthopedics. Exosomes contain various substances such as microRNA. We conducted an integrated analysis of cell-derived exosomes by two stress stimuli, mechanical stress and cytokine stimulation. A human cartilage-like cell line was used. We found that when microRNA-X was overexpressed in cartilage-like cells, it suppressed ADAMTS mRNA. Furthermore, we have found that microRNA-X effect on another unexpected molecule related to the extracellular matrix.
    Next, we found that one exosome surface molecule plays a very important role in the uptake of exosomes cells. Identification of this mechanism has a great impact on cell biology in understanding the signal transduction mechanism of exosomes, and can be expected to have a spillover effect. In order to solve this important problem, it is now necessary to develop new research.

    Adam12 was upregulated prior to Col10a1 during chondrogenic differentiation in wild-type ATDC5 cells. In Adam12-KO ATDC5 cells, following initiation of chondrogenic differentiation, we observed a reduction in Igf-1 expression along with an upregulation of hypertrophy-associated Runx2, Col10a1, and type X collagen protein expressions. In ATDC5 wild-type cells, stimulation with TGF-β1 upregulated the expressions of Adam12 and Igf-1 and downregulated the expression of Runx2. In contrast, in Adam12-KO ATDC5 cells, these TGF-β1-induced changes were suppressed. Adam12 overexpression resulted in an upregulation of Igf-1 and downregulation of Runx2 expression in ATDC5 cells. The findings suggest that ADAM12 has important role in the regulation of chondrocyte differentiation, potentially by regulation of TGF-β1-dependent signaling and that targeting of ADAM12 may have a role in management of abnormal chondrocyte differentiation.

    In this study, we focused on the EMC-degrading enzymes that are important for osteoarthritis, and sought to find compounds that can inhibit the destruction of cartilage matrix by inhibiting the synthesis of EMC-degrading enzymes. We screened 400 kinds of pilot libraries provided by RIKEN. Results of examining the effect of suppressing the expression of ECM-degrading enzymes compound X significantly suppressed the mRNA expression of four extracellular matrix degrading enzymes such as MMP3, MMP13, ADAMTS4, and ADAMTS9, which were induced by inflammation caused by the inflammatory cytokine IL-1β. It also significantly suppressed the expression of the enzyme COX2, which has a role in promoting inflammation.
    It was considered that compound X may be effective in treating OA.

    In this study, we established a quantitative method for serum apoE-rich HDL and showed that apoE-rich HDL increased in obese model mice. In clinical study, multiple regression analysis revealed that triglycerides and adiponectin strongly involved in obesity are significant predictors of apoE-rich HDL-cholesterol levels. However, in the culture experiment of adipocytes, we did not obtain data on which apoE-rich HDL was involved in fat accumulation. In cultured hepatocytes, the production of apoE-rich HDL was increased by the high glucose medium, suggesting that glucose uptake by hepatocytes was significantly involved in the production of apoE-rich HDL. A new research progress is expected in the future in relation to glucose metabolism and the production of E-rich HDL in hepatocytes.

    A new X-ray imaging probe 2Ke2-TIB has been created in addition to Ke4-TIB. These probes were examined for in vivo imaging of articular cartilage by CT using rat osteoarthritic model. A new patent regarding Ke4-TIB has been established on March 24th, 2017. Since we speculate the increasing use of mouse genetic model for drug discovery research, we created a new mouse genetic model by crossing floxed "A" gene mice, encoding a proteoglycan gene abundant in the articular cartilage, with Rosa26-creERT mice. The mice exhibited a dwarfism and articular cartilage degeneration after starting injection of tamoxifen at one week of age. These developments of new imaging probes and a mouse model will contribute to the future research on osteoarthritis drug discovery. A collaboration with a group in the University of Munich has started for nano Xray CT.

    A disintegrin and metalloprotease with thrombospondin type I motifs 1 (ADAMTS1), a member of the matrix metalloproteinase family, inhibits angiogenesis and lymphangiogenesis. ADAMTS1 in endothelial cells is induced by hypoxia and mechanical stress such as blood wall shear stress. We investigated the effects of tumor interstitial fluid pressure (TIFP) on the expression of ADAMTS1 in the tumor tissues. Stromal ADAMTS1 was mainly expressed in neovascular endothelial cells. It was suggested that stromal ADAMTS1 might implicate in vascular fragility and rarefaction, and elevation of TIFP.

    Aggrecan is a major proteoglycan in cartilage and is degraded by aggrecanase. Aggrecanases plays a role in the early stage of osteoarthritis. This research aimed the integrated analysis of microRNAs whose targets are the aggrecanase mRNAs and extracellular matrix proteins. We try to examine how aggrecanases are regulated by microRNAs.
    In this study, we first stimulated chondrocytic cells by cytokine as well as mechanical stress. We then compared the change of microRNA expression between two different stimulations. By using several database, we identified the target gene for microRNAs of interest. Then we added another stimulation condition and selected the microRNA of interest. We next examined the effect of inhibitor of microRNA and confirmed that inhibitor abolished the effect of microRNA. Finally, we confirmed that the target of microRNA is actually proteases that induced in osteoarthritis. In conclusion, we identified the novel microRNA that may play a role in osteoarthritis.

    The regulation of ADAMTS5 is crucial for osteoarthritis. However, little is known for its mechanism. We hypothesized that endocytosis may be involved in ADAMTS5 regulation. First, we found that endocytosis occurred in OUMS-27. We next examined endocytosis-related molecule, LRP-1 and RAP. The mRNA level of receptor-associated protein (RAP), antagonist of LRP-1, was not changed by IL-1 beta stimulation. It is interesting that the small-sized bands were found by Western blotting using anti-LRP-1 antibody after IL-1 beta stimulation. This is considered to be a short LRP-1 and the shedding of LRP-1 may be occurred by IL-1 beta stimulation.

Because ADAMTS4 (aggrecanase-1) and ADAMTS5 (aggrecanase-2) share the substrates, one of these two molecule may compensate the biological function in a single knockout mouse, we decided to produce double knockout mouse.
    The double knockout mice were survived and there was no dwarfism observed. There was no particular abnormality in the tissue development. We then cross double knockout mice with ApoE knockout mouse. ApoE knockout mouse is used for atherosclerosis study. We succeeded to produced triple knockout mice and we gave them high-fat diet. It was interesting that there was a significant difference in the development of atherosclerosis between ApoE single and triple knockout mice.

Therefore we used physiological and biochemical methods. In our study, patients were divided into four groups, 1(normal therapy (NT)), 2(NT + HA treatment), 3(NT + MS) and 4(NT + HA treatment + MS). Uterine collagen C telopeptide (U-CTX) was used as cartilage degradation marker. Patient group 4 significantly decreased U-CTX concentration in compared with other groups. Furthermore, U-CTX levels significantly decreased in patients of slight symptom in compared severe symtom patients.
    In conclusion, our results show that HA treatment with mechanical stimulation in early OA stage attenuate articular degradation in OA patients.

    Abnormalities of the basement membranes in brain small vessels are considered to cause the break-down of blood-brain barrier (BBB) and intracerebral hemorrhage. We established the mouse encephalopathy model by the administration of TNF-alpha intravenously, in which BBB permeability increase transiently. To know the change of type IV collagen, as major component of the basement membranes, in the encephalopathy model, we performed Western blot and immunohistochemistry. The results suggested that the degradation of type IV collagen was associated with the break-down of BBB.

    Tube formationアッセイでは二つのコンストラクト共に有意に血管新生を阻害した。さらに二つのコンストラクトは共にHUVECの増殖を阻害した。一方、平滑筋細胞や線維芽細胞に対しては阻害効果を認めなかった。同様にフローサイトメトリーによる解析でAnnexin-V陽性細胞数はHUVECで有意に増加していたが、他の細胞では認めなかった。担がんマウスを用いた遺伝子導入治療において、二つのADAMTS1はいずれも抗腫瘍増大効果を発揮した。腫瘍内血管数は有意に減少しており、ADAMTS1治療群では腫瘍内の血管に活性型caspaseのシグナルを認めた。以上より、ADAMTS1はプロテアーゼドメイン非依存的に血管内細胞にアポトーシスを起こし、腫瘍の成長を抑制することが明らかとなった。
    さらに、アデノウイルスに全長ADAMTS1を組み込み、アデノウイルス治療によるリンパ管内皮細胞(HMVEC-dLy)への効果を検討した。VEGFC刺激したHMVEC-dLyはVEGF-R3のリン酸化を起こすが、アデノADAMTS1はリン酸化を抑制した。またアデノウイルスによりADAMTS1を導入したMDA-MB231乳がん細胞株はコントロールと比べてHMVEC-dLyの遊走を抑制した。
    ADAMTS1は血管新生・リンパ管新生をそれぞれのメカニズムにより阻害することを明らかにした。

    ADAMTS1 is a matrix metalloproteinase and inhibits angiogenesis. We investigated the effect of ADAMTS1 on lymphangiogenesis. We further examined the relationship between tumor interstitial fluid pressure (TIFP) and tumor growth. We demonstrated that overexpressed-ADAMTS1 transfectants bind to VEGFC and made a complex and dampened the phosphorylation of VEGFR3, inhibiting lymphangiogenesis. Moreover, when VEGFC was injected to enhance lymphangiogenesis in a xenograft mouse model, TIFP was reduced and tumor growth was also attenuated. Finally, we stretched HMVEC-dLys and examined lymphangiogenesis-related genes. Mechanical stress may be involved in the regulation of lymphangiogenesis-related gene expressions in lymphatic endothelial cells.

    We examined the ADAMTS4 expression and distribution in myocardial infarction. ADAMTS4 was strongly induced after myocardial infarction, especially in the infarct marginal zone. In ADAMTS4 null mice, heart development was normal. We then produced myocardial infarction in ADAMTS4 null mice and compared with that in wild type mice. There was no significant difference regarding the survival, inflammatory cell infiltration, and cardiac function after myocardial infarction. Accordingly, it is suggested that other ADAMTS members compensate the role of ADAMTS4 in the null mice in our infarction model.

    ADAMITS1は超急性期虚血においてのみ強く内皮及細胞から分泌され、時間が経過した急性虚血では分泌されない性質を持つ。この実験的事実からADAMTS1は超急性期虚血でのみ内皮細胞に特異的に誘導され分泌されるタンパクであると考えた。そして、この特性を利用して、ADAMTSIを超急性期の虚血を検出するバイオマーカーとして利用できるのではないかと仮説を立て、これを証明するために下記の実験を行った。
    1.ADAMTS1に対するELISA系の確立
    市販されている精製ヒトADAMTS1タンパクを用いてADAMTS1のサンドイッチELISA法を確立した。各社より販売されている抗ヒトADAMTS1抗体および独自に作成したモノクローナル抗体を用いてそれぞれ反応性を検討した。もっとも反応性のよかった抗体を以後の検討に利用することとした。

    心筋梗塞ラットより虚血後、1,3,6,24時間後に血液を採取し、血漿を分離した。経時的なADAMTS1の血漿中レベルの変動について解析を行う予定であったが、血漿とは反応性が不良であったためか、測定感度レベルより低値であった。

    1. Coating method for siRNA on stent was examined. As one of the model cases, Glycosminoglycans were bound on the titanium oxide surface. A basic PTD peptide binding to GAGs was determined by QCM method. Further, the uptake of the peptide into the smooth muscle cells from the titanium surface was quantified. However; the uptake amount was not significantly different from the control. We suppose that the peptide could not stably bound on titanium after the cells were seeded.
    2. Various genes are induced by cytokines when the vascular smooth muscle cells proliferate in stent-restenosis. We predicted the ADAM-TS gene, a subfamily of matrix metaroproteinase, expression in this situation. These might be involved in the remodeling in the processes of restenosis. As a result, one of the ADAM-TS gene is upregurated 3-6 hrs after the IL-1 induction. Promoter of the gene contained putative NFAT-binding sites. NFAT inhibitors could suppress the ADAM-TS gene expression, indicating the induction through NFAT. These results might implicate the possible target of siRNA treatment.
    3. Small stent designed in this project was examined in rat Stent implantation was performed in aorta or femoral artery The implantation in aorta is rather successful compared to that in femoral artery. Narrowing the size and increasing the flexibility is required for stenting in the femoral artery

    2 Distribution of ADAMTS9 in cartilage
    We produced osteoarthritis model in Wister rats. When the cartilage destruction was not so severe, the expression of ADAMTS9 was already induced. Then we examined the expression of ADAMTS9 in developmental knee joint. The knee joint was taken at 0, 7, and 14 weeks after birth in ICR mice, respectively. The expression of ADAMTS9 was observed in mature chondrocyte layer (partially) as well as hypertrophic zone. From these experiments, it is suggested that ADAMTS9 is related to the maturation of chondrocytes in knee joint.

    Diabetic retinopathy is characterized as increased angiogenesis as well as leaky vessels resulted in abnormal bleeding. The aim of our study was to define the role of basement membrane for diabetic retinopathy. We hypothesized that a breakdown or an abnormal organization of basement membrane was the initial step of the pathological change in the diabetic retinopathy that leads to the vulnerability of the vessels.
    We focused on the two components of basement membrane, laminin and type IV collagen.
    1. Leaky vessels in diabetic retinopathy
    Diabetic rat model was made by administration of streptozotocin (STZ) (180mg/kg, i.p.). The blood glucose level was measured. All the rats demonstrated continued high blood glucose level (>250mg/dl). We examined the retina of the diabetic rat by using Evans blue staining. Despite the diabetic state, our rats did not show particular evidence of leaky vessels.
    2. Distribution of basement membrane components in diabetic retinopathy
    We examined the distribution of the major components of basement membrane, laminin and type IV collagen. We used specific antibody against from α1 to α6 chains of type IV collagen and α4 and α5 chain of laminin for the immunofluorescent staining analysis.
    In the vascular basement membrane of the retina, α1 and α2 chains of type IV collagen was observed, while internal limiting membrane (ILM) showed positive signals for α5 and α6 chains of collagen IV as well as α1 and α2 chains of collagen IV.
    3. The change of basement membrane components and the diabetic retinopathy
    We concluded that the establishment of proper model for diabetic retinopathy is crucial. The transgenic animal of basement membrane may be of interest.

    [1]Molecular and cellular analysis of the new basement membrane like structure fractone.
    We detected the basement mambrane molecules such as laminin and type IV collagen in the mouse fractone by immunohistochemistry. Especially, several laminin chains and type IV collagen chains were present in the fractone, but fibronectin was not expressed there. Moreover, the fractone was distributed around almost all of subventricular zone in the brain and spinal code but it was not present in some areas of the third and forth ventricle. Developmental studies showed that the fractone started its expression around subventricular zone at postnatal day seven, and then expression pattern was limited to lateral part of ventricle at postnatal day 14. Furthermore, we recognized the fractone structure more precisely using immunoelectron-microscopic analysis.
    [2]Identification and separation of neural stem cells from subventricular zone
    We tried to separate neural stem cells from adult mouse subventricular zones and allowed them to further differentiate into neurons and astrocytes in various conditions. To set-up differentiation conditions, we prepared substrates rich in matrix macromolecules.
    [3]Control of stem cell differentiation by extracellular matrix
    We successfully culture neurospheres prepared from subventricular zone of the lateral ventricles and set-up conditions to further differentiate into neurons and astrocytes.

    血管新生を抑制するマルチプレキシンコラーゲンの性質を調べる意味で、以下の実験を行い、結果を得ることが出来た。マルチプレキシンコラーゲンの一つであるXVIII型コラーゲンは、そのカルボキシル末端の約250アミノ酸残基のNCドメインの中にはエンドスタチンとよばれ、腫瘍の周囲の血管新生を抑制することが1997年に初めて報告されてから、有望な抗がん作用を示す薬剤になりうる可能性を秘めていると思われて来た。しかしながら、いくつかの研究グループはその部分のペプチドに再現性を認めず、その作用機序を含め未解決の部分は多い。そこで、今回私どもは、XVIII型コラーゲンを多く産生する肝臓細胞株を探し出し、それをヌードマウスに打つことによって作られる腫瘍塊を作成した。そこで、XVIII型コラーゲンに特異的モノクローン抗体を担癌マウスに接種することにより、癌塊が増悪腫大するかどうかを観察することとした。その結果、この特異的モノクローン抗体はがん細胞をアポトーシスに導くことなく、肝癌の容積の増大を認めた。しかしながら、この特異抗体だけでは腫瘍細胞の増殖を促進することはなさそうであった。これらの結果は、エンドスタチンの抗腫瘍効果を支持する重要な所見であり、それだけでなく今回使用したものクローン抗体は、特異的にXVIII型コラーゲンに反応し、エンドスタチンの抗腫瘍効果を抑制することにまで至ったものであり、重要な知見であると思われる。

    1 Expression analysis of novel aggrecanase
    RNA was extracted from IL-1 b stimulated chondrosarcoma cells and chondrocytes and the aggrecanase expressions were analyzed by quantitative RT-PCR. When compared with fibroblasts, chondrosarcoma cells and chondrocytes showed higher induction of novel aggrecanase, thus indicating this novel aggrecanase is IL-1 induced specifically in cartilage cells. When chondrosarcoma cells were stimulated with IL-1b and TNFa, novel aggrecanase induced synergistically.
    2 Antibody against novel aggrecanase
    We raised a polyclonal antibody against novel aggrecanase, and checked its specificity by Western blotting. A novel aggrecanase was induced by IL-1b stimulation by Western blot analysis.
    3 KO mouse
    We got hetero mice
    4 Signal mechanism for novel aggrecanase induction
    MAP kinase inhibitor(PD98059,SB203580) were added to IL- 1b stimulated chondrosarcoma cells and the signaling pathway was determined.

    ADAMTS-1(A Disintegrin And Metalloprotease with ThromboSpondin motifs-1)は約5年程前に発見された新しい細胞外マトリックス(ECM)分解酵素群の中の一構成メンバーである。急性心筋梗塞後の左室リモデリングには、マトリックスメタロプロテアーゼ(MMP)をはじめとするECM分解酵素の重要性が最近認識されている。
    予備実験としてADAMTS-1の心筋梗塞における発現動態をノーザンブロット法にて検討したところ、梗塞急性期に非常に強い発現がみられADAMTS-1は従来のMMPとは異なった役割を持つ可能性が示唆された。
    1 ADAMTS-1に影響を与える薬剤の検討
    ラット実験的心筋梗塞モデルにアンジオテンシン変換酵素阻害剤を投与し、ADAMTS1発現へ与える影響を検討した。コントロールとして、コラーゲンを用いて、比較検討したが、ADAMTS1の発現量には有意な変化は認められなかった。また、我々の梗塞モデルでは、梗塞後比較的早期の段階では、コラーゲンがむしろ上昇する傾向にあった。このことはこれまでの報告では見られない変化であり、我々の梗塞モデルにのみ見られる現象なのか、または解析方法に問題があるために見られた変化なのか解決することはできなかった。
    2 ノックアウトマウスを用いた検討
    ノックアウトマウスを作製し、維持管理している金沢大学がん研究所久野耕嗣博士と連絡を取ったが、残念ながら共同研究の実施にまでは至らなかった。RNA干渉法など他の方法を用いての解析が有効と考えられた。
    これらの研究成果は、日本循環器学会学術集会などにおいて発表し、報告した。

    We report the molecular cloning of a new member of the transmembrane-type immunoglobulin superfamily and designate the encoded protein as limitrin since it selectively localized to glia limitans in mouse brain. Limitrin cDNA was obtained using a subtractive hybridization procedure designed to identify molecules responsible for blood-brain barrier function. Western blots using a limitrin-specific antibody demonstrated that the gene product is expressed significantly in mouse brain and primary murine astrocytes, and is distributed in the plasma membrane. Immunohistochemical studies using confocal and electron microscopy clearly demonstrated highly polarized localization in astroglial endfeet in the perivascular region and under the pia mater in vivo. Limitrin is expressed in spinal cord and many areas of the brain but not in the median eminence or subfornical organ (the circumventricular organs) where the blood-brain barrier is lacking. Disruption of the blood-brain barrier by cold injury resulted in a drastic reduction in limitrin expression. Furthermore, during retrieval from cold injury the increased expression of limitrin in perivascular endfeet correlated with the recovery of angiogenesis in capillaries within the lesion margins. Our results suggest that limitrin is physically and functionally associated with the blood-brain barrier, implying that this protein may be useful as a diagnostic determinant of barrier integrity.

    本研究の目的は、がん休眠療法の遺伝子治療の開発である。IV型コラーゲンα3鎖のNC1ドメインは、tumstatinとも呼ばれ、血管新生阻害作用を持つことが報告されている。しかしながらIV型コラーゲンα3鎖のNC1ドメインを治療に利用するにあたっては、同部位がGoodpasture症候群の自己抗原認識部位であることから、がん特異的な遺伝子発現が重要と考えられた。
    そこでhTERT(ヒトテロメラーゼ遺伝子)のプロモーター領域を組み込んだベクターにIV型コラーゲンα3鎖のNC1ドメインを下流に位置することにより、がん細胞特異的遺伝子導入法を試みた。コントロールとして、LacZをいれたベクターによる検討では、hTERTの発現がない細胞である正常内皮細胞には、観察しえた限りではX-gal染色は見られなかった。内皮細胞の他に心臓由来線維芽細胞を用いた実験でも同様の結果が得られた。がん細胞(PC-3,DU145)においてのみ、LacZの発現が見られた。この結果は、CMVベクター下にLacZを挿入した(細胞特異性がない)ものを用いたものと比較して著しい差は認められなかった。
    NC1ドメインの遺伝子発現効率は、LacZ細胞とほぼ同等であると考えられたが、タンパクレベルの発現は充分なものではなかった。血管新生阻害効果を治療応用するには、発現効率を高めることが必須であり、アデノウイルスを用いた新しい発現カセットを作成が重要と考えられた。

    ADAMファミリーのうち、ADM-10とADAM-17はαセクレターゼ機能を持つことが知られているが、ADAMTSが同様な機能を持つか検討した。
    まず、基礎的実験としてADAMTS-1はその遺伝子発現がリポポリサッカライド刺激により、各臓器において発現が上昇することから炎症において何らかの役割を持つことが示唆されている。そこで、ラット実験的心筋梗塞モデルを用いてADAMTS-1の発現形式をノーザンブロット法にて検討した。ADAMTS-1は非梗塞心臓では弱い発現しか認めなかったが、梗塞心においては、梗塞後6時間でその発現が大きく上昇していた。
    マウス脳におけるADAMTSの発現をADAMTS-1〜7において検討したが、いずれもそれほど強くなかった。海外共同研究として、アミロイド前駆体蛋白を強制発現し、恒常的に発現する細胞株を樹立している、アラバマ大学Fukuchi教授らと共同実験を開始した。同細胞株は、通常の神経系細胞よりも過剰にアミロイド前駆体蛋白を発現している。これまでの検討によって過剰なアミロイド蛋白前駆体が細胞表面及び培養上清中に存在することが確認された。この実験系において過剰なアミロイド前駆体の切断がαセクレターゼによって制御されているかどうかを検討する目的でこの細胞系におけるαセクレターゼ発現の検討を開始した。実験の条件検討が複雑であり、切断の確認は困難であった。今後は、In vivoの系における実験系の確立およびアルツハイマー脳におけるADAMTSの発現解析が重要と考えられた。

    To investigate new aggrecanase, we have done the following experiments and got some data.
    1) Various ADAMTS-specific primers were designed and RT-PCR was performed. We cultured human chondrosarcoma cell lines OUMS-27 (Okayama University Medical School-27) and stimulated with interleukine-1 beta (IL-1β). To determine gene expression quantitatively, we employed real-time RT-PCR method. Briefly, total RNA was extracted and then DNAse treatmeat was done to eliminate contaminating genomic DNA. After reverse transcribed with random primers and enzymes, cDNA was served as a template for RT-PCR. GAPDH was used for the internal control.
    2) The expression and gene regulation by IL-1β was different amonf the ADAMTS-1,4, and -5, which were reported to have aggrecan cleaving property in vitro. We also investigated other ADAMTS gene expressions.
    3) We identified another up-regulating ADAMTS gene by IL-1β in OUMS-27 cells. We raised polyclonal antibody against this new ADAMTS gene using peptide sequence of this ADAMTS.
    4) We also started to making knock-out mouse for this gene. We screened mouse genomic library and identified several clones including this new ADAMTS gene. Under the collaboration with Dr. Apte's lab in the USA, we started to put our clones to ES cells.
