Developmental 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 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 کاملRoundup inhibits steroidogenesis by disrupting steroidogenic acute regulatory (StAR) protein expression.
Recent reports demonstrate that many currently used pesticides have the capacity to disrupt reproductive function in animals. Although this reproductive dysfunction is typically characterized by alterations in serum steroid hormone levels, disruptions in spermatogenesis, and loss of fertility, the mechanisms involved in pesticide-induced infertility remain unclear. Because testicular Leydig cel...
متن کاملCholesterol binding is a prerequisite for the activity of the steroidogenic acute regulatory protein (StAR).
Steroidogenesis depends on the delivery of cholesterol from the outer to the inner mitochondrial membrane by StAR (steroidogenic acute regulatory protein). However, the mechanism by which StAR binds to cholesterol and its importance in cholesterol transport are under debate. According to our proposed molecular model, StAR possesses a hydrophobic cavity, which can accommodate one cholesterol mol...
