Cloning, Expression and Hormonal Regulation of Steroidogenic Acute Regulatory Protein Gene in Buffalo Ovary
In mammalian ovary, steroidogenic acute regulatory (StAR) protein mediates the true rate-limiting step of transport of cholesterol from outer to inner mitochondrial membrane. Appropriate expression of StAR gene represents an indispensable component of steroidogenesis and its regulation has been found to be species specific. However, limited information is available regarding StAR gene expressio...
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 کاملThe effects of low-level Pb on steroidogenic acute regulatory protein (StAR) in the prepubertal rat ovary.
Estradiol (E2) is suppressed in prepubertal females exposed maternally to lead (Pb); thus, we assessed effects of Pb on ovarian steroidogenic acute regulatory protein (StAR) as a potential mechanism for this action. Adult Fisher 344 females were dosed with 12 mg of lead acetate per ml of Pb acetate (PbAc) or sodium acetate (NaAc; control), beginning 30 days prior to breeding and continuing unti...
متن کاملSpatio-temporal expression patterns of steroidogenic acute regulatory protein (StAR) during follicular development in the rat ovary.
The steroidogenic acute regulatory protein (StAR) is a vital mitochondrial protein that is indispensable for the synthesis of steroid hormones in the steroidogenic cells of the adrenal cortex and the gonads. Recent studies have shown that StAR enhances the conversion of the substrate for all steroid hormones, cholesterol, into pregnenolone, probably by facilitating cholesterol entry into the in...
