We studied the involvement of the ERK cascade in human chorionic gonadotropin (hCG)-induced steroidogenesis by primary cultures of immature rat Leydig cells. Our findings indicate that protein kinase A and protein kinase C function as upstream kinases in connection with transduction of the signal from the gonadotropin receptor to the ERK cascade. These MAPKs enhance the stimulatory effects of h...
BACKGROUND While menopause results in the loss of cyclic steroid production, evidence exists for persistent, albeit reduced, ovarian androgen production. In order to continue to synthesize ovarian androgens, the steroidogenic enzymes necessary for androgen biosynthesis must be present. Few studies have selectively analysed some of the steroidogenic enzymes present in the post-menopausal ovary (...
Cisplatin (CIS) is used in the treatment of cancer, but its nonspecific systemic actions lead to toxic effects on other parts of the body. This study investigated the severity of CIS toxicity by increasing its dose over a constant time period. Sprague Dawley rats were divided into five treatment groups and control group with CIS (2, 4, 6, 8, and 10 mg/kg) administered intraperitoneally for 5 da...
objective: the role of wnt signaling and its antagonist; secreted frizzled related protein type 4 (sfpr4) was reported in rodent ovarian follicular development. this study examines immunolocalization of sfrp4 in ovaries of polycystic ovary (pco) rat model and evaluates its role in follicular growth arrest and its premature differentiation. materials and mathods: pco was induced with daily admin...
