Repression of the rat steroidogenic acute regulatory (StAR) protein gene by PGF2α is modulated by the negative transcription factor DAX-1
The steroidogenic acute regulatory protein (StAR) is thought to mediate the rapid increase in steroid hormone biosynthesis by facilitating cholesterol transport to the inner mitochondrial membrane. Recent stud...

Expression and hormonal regulation of the high-density lipoprotein (HDL) receptor scavenger receptor class B type I messenger ribonucleic acid in the rat ovary
Since cholesterol delivery to the ovary is an essential regulated step in steroidogenesis, mRNA levels for the Scavenger Receptor Class B Type I (SR-BI), a putative high-density lipoprotein receptor (HDL-R), w...

Hormone and prostaglandin F2α regulation of messenger ribonucleic acid encoding steroidogenic acute regulatory protein in human corpora lutea
Steroidogenic acute regulatory (StAR) protein mediates the rapid increase in steroid hormone biosynthesis in response to tropic hormones by facilitating transport of cholesterol into the inner mitochondrial me...

Prostaglandin F2α reduces steroidogenic acute regulatory (StAR) protein messenger ribonucleic acid expression in the rat ovary
Steroid biosynthesis begins with the enzymatic conversion of cholesterol to pregnenolone. This reaction is catalyzed by the cytochrome P450 side-chain cleavage enzyme (P450scc), which is located on the matrix ...

Hormonal regulation of steroidogenic acute regulatory (StAR) protein messenger ribonucleic acid expression in the rat ovary
Steroidogenic acute regulatory (StAR) protein is thought to mediate the rapid increase in steroid hormone biosynthesis in response to tropic hormones by facilitating cholesterol transport to the inner mitochon...
