We report a rare case of Graves' disease associated with struma ovarii. A 26-year-old Japanese woman had preexisting Graves' disease and was positive for TSH receptor antibody. She had been on antithyroid medication at presentation. She noted a mass in the lower left abdomen, which was diagnosed as a left struma ovarii by radiological work-up including computed tomography, magnetic resonance imaging and scintigraphy. The surgically excised teratomatous tumor, containing cystic spaces with thyroid tissue, was histologically proved to be struma ovarii. Since thyroid function tests and TSH receptor antibody did not change after surgery, her hyperthyroidism was considered to be due to Graves' disease. Our case was diagnosed as struma ovarii before surgery using various imaging studies.

The expression of pregnane X receptor and its target gene, cytochrome P450 3A1, in perinatal mouse

H Masuyama, Y Hiramatsu, Y Mizutani, H Inoshita, T Kudo

MOLECULAR AND CELLULAR ENDOCRINOLOGY 172 ( 1-2 ) 47 - 56 2001年2月

記述言語：英語出版者・発行元：ELSEVIER SCI IRELAND LTD

Recently, pregnane X receptor (PXR) has been described to mediate the genomic effects of several steroid hormones, such as progesterone (P), glucocorticoid (Dex), pregnenolone (Preg), and xenobiotics through the cytochrome P-450 3A gene family (CYP3A), which are monooxygenases, responsible for the oxidative metabolism of some endogenous substrates and xenobiotics. In the present study, we used a transient transfection reporter gene expression assay of COS-7 cells to demonstrate that P, Dex and Preg significantly stimulate PXR-mediated transcription at relatively high concentration comparable with that of progesterone near term pregnancy. In yeast two-hybrid protein interaction assay, PXR interacted with nuclear receptor coactivator proteins, SRC1, RIP140, and SUGI in a ligand-dependent manner. The expression of PXR mRNA was observed in the liver, intestine, uterus, ovary and placenta. The expressions of PXR mRNA in the liver and ovary increased towards term about fifty-fold compared with that of non-pregnancy and decreased postpartum. Its expression in the placenta was not drastically changed towards term. CYP3A, a target gene of PXR, was also expressed in the liver, ovary, and placenta. The expressions of CYP3A mRNA as well as PXR in the liver and ovary increased about 20-fold during prenatal period. These data suggest: that PXR may play certain roles in perinatal period, possibly in the protection of the feto-maternal system from the toxic effect of endogenous steroids and foreign substrates.

Streptozotocin-induced diabetic pregnant rats exhibit signs and symptoms mimicking preeclampsia

The number of patients with hypertension, obesity, diabetes, and hyperlipidemia is increasing. This tendency is observed in pregnant women, in whom many obstetrical and perinatal complications occur. The prevention of these abnormalities is important in reducing perinatal mortality and the risk of coronary disease. We established a pregnant rat model with diabetes and signs and symptoms mimicking preeclampsia. On day 6 of pregnancy, streptozotocin (STZ) or citrate buffer was injected into the tail vein, After STZ administration, plasma glucose was increased within 48 hours and sustained at a high level until day 20 of pregnancy, and plasma insulin was decreased. Fetuses from STZ-treated mothers were growth-restricted, and plasma glucose was 6-fold higher in fetuses of STZ-treated versus control rats. The systolic blood pressure, urinary protein, and hematocrit were increased significantly in STZ-treated rats. Total cholesterol and triglycerides were also elevated in STZ-treated rats, but plasma leptin levels were decreased. The STZ-induced diabetic pregnant rat model exhibited preeclampsia, hemoconcentration, hyperlipidemia, hypoleptinemia, and intrauterine growth restriction. This model closely mimics the features of human pregnancy complicated by diabetes and is useful for the basic study of the pathophysiology of pregnancy with diabetes. Copyright (C) 2000 by W.B.

Endocrine disrupting chemicals, phthalic acid and nonylphenol, activate Pregnane X receptor-mediated transcription

H Masuyama, Y Hiramatsu, M Kunitomi, T Kudo, PN MacDonald

MOLECULAR ENDOCRINOLOGY 14 ( 3 ) 421 - 428 2000年3月

Recently, Pregnane X receptor (PXR), a new member of the nuclear receptor superfamily, was shown to mediate the effects of several steroid hormones, such as progesterone, glucocorticoid, pregnenolone, and xenobiotics on cytochrome P450 3A genes (CYP3A) through the specific DNA sequence for CYP3A, suggesting that PXR may play a role in steroid hormone metabolism. In this paper, we demonstrated that phthalic acid and nonylphenol, endocrine-disrupting chemicals (EDCs), stimulated PXR-mediated transcription at concentrations comparable to those at which they activate estrogen receptor-mediated transcription using a transient reporter gene expression assay in COS-7 cells. However, bisphenol A, another EDC, had no effect on PXR-mediated transcription, although this chemical significantly enhanced ER-mediated transcription. In the yeast two-hybrid protein interaction assay, PXR interacted with two nuclear receptor coactivator proteins, steroid hormone receptor coactivator-1 and receptor interacting protein 140, in the presence of phthalic acid or nonylphenol. Thus, EDC-occupied PXR may regulate its specific gene expression through the receptor-coactivator interaction. In contrast, these EDCs had no effect on the interaction between PXR and suppressor for gal 1, a component of proteasome. Finally, the expression of CYP3A1 mRNA in the liver of rats exposed to phthalic acid or nonylphenol markedly increased compared with that in rats treated with estradiol, bisphenol A, or ethanol as assessed by competitive RT-PCR. These data suggest that EDCs may affect endocrine functions by altering steroid hormone metabolism through PXR.
