Low progesterone levels are associated with luteal phase deficiency in women with polycystic ovary syndrome (PCOS). The mechanisms regulating progesterone biosynthesis in the granulosa cells from women with PCOS is largely unknown. Fractalkine is expressed in human ovaries, and is reported to regulate progesterone production in granulosa cells of healthy women. In the current study, we aimed to...
BACKGROUND Main function of corpus luteum is progesterone synthesis that is significantly accompanied with an increase in levels of mRNA encoding of steroidogenic enzymes known as luteal markers. 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 Immatur...
We investigated the expression characteristics of matrix metalloproteinases (MMP)-2 and MMP-9 in the ovaries of normal adult guinea pigs during the estrous cycle. The estrous cycle was classified according to the appearance of the vaginal orifice and by vaginal exfoliated cell smears. Guinea pigs that had experienced at least two normal estrous cycles were selected. Ovaries were collected from ...
StAR (steroidogenic acute regulatory) proteins and proteins with StAR-related lipid transfer (START) domains are involved in lipid transport and metabolism, signal transduction, and transcriptional regulation. In this present study we characterized the StARD9 gene by bioinformatical methods. The human StARD9 gene (syn. KIAA1300), consisting of 11 exons, was located within human genome sequence ...
The circadian rhythm in glucocorticoid secretion by the adrenal cortex was long considered to be a product and direct reflection of the circadian rhythm of ACTH secretion by the anterior pituitary. However, data have accumulated for several years indicating that changes in circulating ACTH cannot fully explain the adrenal rhythm, and under many conditions there is a dissociation between ACTH an...
