A 73-year-old Japanese woman was referred for examination of right flank pain and progressive hypertension. Abdominal CT incidentally detected a right adrenal mass 8 cm in size. The tumor exhibited isodensity by CT and contained high-intense lesion by T2-weighted MRI. Scintigraphy with I-131-metaiodobenzylguanidine and I-131-adosterol showed no abnormal uptake by whole body scan. Positron emission tomography scan with F-18-2-fluoro-D-deoxyglucose demonstrated an exclusive uptake in the right adrenal mass. Adrenocortical hormone levels and catecholamine secretion were within normal range; however, the level of serum neuron-specific enolase (NSE) was found to be markedly high. After controlling systemic blood pressure with an alpha 1-blocker, the right adrenal tumor was surgically removed, along with the right kidney and inferior vena cava which adhered to it. The tumor was pathologically proven to be leiomyosarcoma, which was immunohistochemically positive with a-smooth muscle actin and negative with CD57, S-100 and c-kit proteins. Notably, NSE protein was massively expressed in the resected tumor. After surgery blood pressure was controlled with regular medication and serum NSE levels have since normalized. The possibility of leiomyosarcoma should be kept in mind in adrenal incidentalomas with rapid growth and atypical radiological images. Our findings suggest that circulating NSE levels may be clinically useful for early detection of recurrence.

Language：English Publisher：SOC ENDOCRINOLOGY

Involvement of peroxisome proliferator-activated receptor-gamma (PPAR-gamma) activation and bone morphogenetic protein (BMP) signaling in regulating cell proliferation and hormonal production of pituitary tumors has been reported, although the underlying mechanism remains poorly understood. Here, we investigated regulatory roles of PPAR alpha. and PPAR gamma in gonadotropin transcription and cell mitosis modulated by pituitary activin/BMP systems using a mouse gonadotropinoma cell line L beta T2, which expresses activin/BMP receptors, transcription factor Smads, PPAR alpha, and PFARy. In L beta T2 cells, BMP signaling shown by Smad 1/5/8 phosphorylation and Id-1 transcription was readily activated by BMPs. A PPAR gamma agonist, pioglitazone significantly reduced BMP-induced DNA synthesis by L beta T2; whereas the PPARa agonist, fenofibric acid, did not. In accordance with the effects on cell mitosis, pioglitazone but not fenofibric acid significantly decreased BMP-induced Id-1-Luc activation. Neither fenofibric acid nor pioglitazone affected activin signaling detected by (CAGA)(9)-Luc activity. Both PPAR alpha and PPAR gamma ligands directly suppressed transcriptional activities of FSH beta, LH beta, and GnRHR. Activation of PPARg. and PPAK gamma increased mRNA levels of follistatin, but did not affect the expression of follistatin-related gene. Thus, PPAR agonists not only directly suppress gonadotropin transcription and BMP signaling, but also inhibit the biological actions of activins which facilitate gonadotropin transcription through upregulating follistatin expression. In addition, pioglitazone increased BMP ligands mRNA, but decreased activin-beta B mRNA in L beta T2 cells. Collectively, PPAR activation differentially regulates gonadotrope cell proliferation and gonadotropin transcription in a ligand-dependent manner.

Bone morphogenetic proteins (BMPs) play critical roles in folliculogenesis by modulating the actions of follicle-stimulating hormone (FSH) in the ovary. However, the effects of FSH on the BMP system remain unknown. Here, we have investigated the effects of FSH on BMP signaling using the human granulosa-like tumor cell line KGN. KGN cells express BMP type 1 and type II receptors and the BMP signaling molecules SMADs. FSH administration upregulated BMP type IA (BMPR1A) and IB (BMPR1B) receptors, activin type II receptor (ACVR2), and BMP type II receptor (BMPR2). FSH also augmented SMAD1 and SMAD5 expression, and conversely, FSH suppressed the expression of the inhibitory SMADs, SMAD6 and SMAD7. Bioassays revealed that FSH enhances BMP-induced SMAD1/5/8 phosphorylation and cellular DNA synthesis induced by BMP6 and BMP7. Since overexpression of BMPR1A and BMPR1B, but not SMADs, significantly enhanced the BMP responses, these type I receptors were revealed to be limiting factors for BMP signaling in KGN cells. BMPs significantly suppressed progesterone synthesis induced by forskolin and dibutyryl-cAMP (BtcAMP) but had no effect on estradiol induced by the same factors. KGN cAMP levels induced by forskolin were not altered by BMPs, suggesting that BMPs regulate steroidogenesis at a level downstream of cAMP synthesis in KGN cells. In this regard, BMPs specifically reduced the STAR transcription, whereas the levels of CYP11A, HSD3B2, and CYP19 stimulated by forskolin as well as BtcAMP were not altered. Collectively, the two major factors, FSH-cAMP pathway and BMP system, are reciprocally and functionally linked. Given that BMPs downregulate FSH receptors in KGN cells, this interaction may contribute to finetuning of the mutual sensitivity toward BMP ligands and FSH.

Involvement of bone morphogenetic protein-6 in differential regulation of aldosterone production by angiotensin II and potassium in human adrenocortical cells

ENDOCRINOLOGY 147 ( 6 ) 2681 - 2689 2006.6

Language：English Publisher：ENDOCRINE SOC

Aldosterone production is modified by several growth factors that reside in the adrenal. We have recently reported the existence of a bone morphogenetic protein (BMP) system in human adrenocortical cells, in which BMP-6 augments aldosterone synthesis. Here, we investigated functional roles of BMP-\6, focusing on the differential regulation of aldosterone synthesis induced by angiotensin (Ang) II and potassium (K). In human adrenocortical H295R cells, BMP-6 augmented Ang II-induced CYP11B2 transcription and mRNA and aldosterone roduction but had no effect on K-induced aldosterone production. Inhibition of endogenous BMP-6 action by neutralizing antibodies impaired aldosterone production induced by Ang II but not that induced by K. Blockage of ligand-receptor binding using extracellular domain (ECD) of BMP type I receptors revealed that ECDs to activin receptor-like kinase (ALK)-2 and ALK-3 significantly reduced the aldosterone production induced by Ang II. None of the type I-receptor ECDs tested had any effect on K-induced aldosterone levels. Overexpression of a dominant negative-activin type II receptor construct selectively decreased Ang II-induced aldosterone production without having any effect on K-induced aldosterone production. BMP type II receptor-dominant negative had no effect on aldosterone induced by either Ang II or K. These results infer that BMP-6 acts through ALK-2, ALK-3, and activin type II receptor receptors in adrenocortical cells. BMP-6 pretreatment extends the induction of ERK1/2 phosphorylation by Ang II and treatment with ECDs to ALK-2 and ALK-3 impaired Ang II-induced ERK phosphorylation. The specific inhibitor of ERK activation, U0126, suppressed the activation of CYP11B2 transcription induced by BMP-6 without affecting Smad phosphorylation and Tlx2-Luc activity. Collectively, the endogenous BMP-6 system plays critical roles in aldosterone production between Ang II and K through ERK signaling pathway.

Functional roles of the bone morphogenetic protein system in thyrotropin signaling in porcine thyroid cells

J Suziki, F Otsuka, M Takeda, K Inagaki, T Miyoshi, Y Mimura, T Ogura, H Doihara, H Makino

BIOCHEMICAL AND BIOPHYSICAL RESEARCH COMMUNICATIONS 327 ( 4 ) 1124 - 1130 2005.2

Language：English Publisher：ACADEMIC PRESS INC ELSEVIER SCIENCE

We uncovered a new regulation of thyrocyte function by bone morphogenetic protein (BMP) under the influence of thyrotropin (TSH) using primary culture of porcine thyrocytes. The BMP type I receptors, ALK-2 (ActRIA), -3 (BMPRIA), and -6 (BMPRIB), were expressed in porcine thyrocytes, while ALK-6 was not detected in human thyroid. Treatment with BMP-2,-4,-6,-7, and TGF-beta1 exhibited a dose-dependent suppression of DNA synthesis by porcine thyrocytes. BMP-2, -4, -6, -7, and TGF-beta1 suppressed TSH receptor mRNA expression on thyrocytes, which was consistent with their suppressive effect on TSH-induced cAMP synthesis and TSH-induced insulin-like growth factor-1 expression. Activin exhibited minimal suppression of thyrocyte DNA synthesis and did not exhibit suppressive effects on TSH receptor mRNA expression. Phosphorylated Smad1/5/8 was detected in the lysates of porcine thyrocytes treated with BMP-2, -4,-6, and -7. However, in the presence of TSH, BMP-6 and -7 failed to activate Smad1/5/8 phosphorylation and 3TP-reporter activity, whereas BMP-2 and -4 maintained clear activation of the BMP signaling regardless of the presence of TSH. This diverged regulation of thyroid BMP system by TSH is most likely due to the reduction of ALK-6 expression caused by TSH. Thus, the thyroid BMP system is functionally linked to TSH actions through modulating TSH receptor expression and TSH, in turn, selectively inhibits BMP signaling. Given that BMP system is present in human thyroid and the expression pattern of ALK-2 and BMPRII is different between follicular adenomas and normal thyroid tissues, the endogenous BMP system may be involved in regulating thyrocyte growth and TSH sensitivity of human thyroid adenomas.
