The steroidogenic acute regulatory protein is indispensable for the biosynthesis of steroid hormones. Steroidogenic acute regulatory protein mediates the rate-limiting step in steroidogenesis, the transfer of cholesterol from the outer mitochondrial membrane to the inner mitochondrial membrane where it is cleaved to pregnenolone. Its essential role in steroidogenesis was shown when it was disco...
background: polycystic ovary syndrome (pcos) is one of the most common endocrine women’s disorders in reproductive age. hyperandrogenism has a critical role in the etiology of pcos and it can cause fault in steroidogenesis process. during steroidogenesis, steroidogenic acute regulatory protein (star) seems to increase the delivery of cholesterol through mitochondrial membrane. therefore, polymo...
The adipocyte-derived hormone leptin is a central modulator of food intake, metabolism and neuroendocrine functions. It is also involved in a physiological loop linking the activity of the hypothalamo-pituitary-adrenal axis and adipose tissue. At the adrenal level, leptin has been shown to antagonize the effects of ACTH on glucocorticoid biosynthesis by decreasing the expression of various enzy...
Although the role of arachidonic acid (AA) in angiotensin II (ANG II)- and potassium-stimulated steroid production in zona glomerulosa cells is well documented, the mechanism responsible for AA release is not fully described. In this study we evaluated the mechanism involved in the release of intramitochondrial AA and its role in the regulation of aldosterone synthesis by ANG II in glomerulosa ...
background: objective: this study was designed to evaluate effects of lithium chloride on the release of steroid hormones and steroidogenic enzymes in gonadotropin-stimulated rats. materials and methods: immature 23 days old wistar rats were divided into 10 groups; each group comprised of 8 rats, and induced with single injection of pregnant mare’s serum gonadotrophin (pmsg) and followed by...
