Abstract excerpt
PGF2alpha, working via protein kinase C, may inhibit transcription of the StAR gene through negative regulatory factors. Administration of PGF2alpha increased c-Fos mRNA with a corresponding reduction in StAR mRNA. A search of the rat StAR promoter revealed three putative AP-1 elements at bp positions -85, -187 and -1561, which demonstrated specific binding of c-Fos by mobility shift assays. Co-transfection of...
