Diazinon 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 کاملDevelopmental roles of the steroidogenic acute regulatory protein (StAR) as revealed by StAR knockout mice.
Steroidogenic acute regulatory protein (StAR) is essential for adrenal and gonadal steroidogenesis, stimulating the translocation of cholesterol to the inner mitochondrial membrane where steroidogenesis commences. StAR mutations in humans cause congenital lipoid adrenal hyperplasia (lipoid CAH), an autosomal recessive condition with severe deficiencies of all classes of steroid hormones. We pre...
متن کاملSteroidogenic acute regulatory protein (StAR) retains activity in the absence of its mitochondrial import sequence: implications for the mechanism of StAR action.
Steroidogenic acute regulatory protein (StAR) plays a critical role in steroid hormone biosynthesis, presumably by facilitating the delivery of cholesterol to P450scc in the inner mitochondrial membranes. StAR is synthesized as a 37-kDa preprotein that is processed to a 30-kDa mature form by cleavage of an N-terminal mitochondrial import sequence. To identify structural features required for St...
