Differential use of signal transduction pathways in the gonadotropin-releasing hormone-mediated regulation of gonadotropin subunit gene expression.
The regulation of LH and FSH subunit gene expression is under the control of GnRH. Physiological changes in the frequency of pulsatile GnRH release from the hypothalamus result in differential stimulation of alpha-, LHbeta-, and FSHbeta-gene expression. Previous studies indicate that the GnRH receptor couples to G proteins of the G(q/11) family, with phosphoinositide turnover and its resultant ...
متن کاملDiazinon interrupts ovarian steroidogenic acute regulatory (StAR) gene transcription in gonadotropin-stimulated rat model
Organophosphate pesticides are considered as endocrine disruptors that interfere with reproductive functions. The corpus luteum (CL) is a transient endocrine gland that produces progesterone, a crucial hormone for a successful beginning and maintenance of pregnancy. Steroidogenic acute regulatory protein (StAR) facilitates the rate-limiting transfer of cholesterol from the outer mitochondrial m...
متن کاملRegulation of gonadotropin receptor gene expression.
The receptors for the gonadotropins differ from the other G protein-coupled receptors by having a large extracellular hormone-binding domain, encoded by nine or ten exons. Alternative splicing of the large pre-mRNA of approximately 100 kb can result in mRNA species that encode truncated receptor proteins. In this review we discuss the regulation of gonadotropin receptor mRNA expression and the ...

متن کاملFox tales: regulation of gonadotropin gene expression by forkhead transcription factors.
Luteinizing hormone (LH) and follicle-stimulating hormone (FSH) are produced by pituitary gonadotrope cells and are required for steroidogenesis, the maturation of ovarian follicles, ovulation, and spermatogenesis. Synthesis of LH and FSH is tightly regulated by a complex network of signaling pathways activated by hormones including gonadotropin-releasing hormone, activin and sex steroids. Memb...
