Cadmium stimulates transcription of the cytochrome p450 side chain cleavage gene in genetically modified stable porcine granulosa cells.

We investigated the effects of cadmium (Cd2+) on transcription of the cytochrome p450 side chain cleavage (p450scc) gene and on progesterone synthesis in stable granulosa cells. We used the stable porcine granulosa cell line, JC-410, genetically modified to express a luciferase genomic construct carrying 2320 base pairs (bp) of the p450scc gene promoter (p450scc-2320-LUC). A construct containing only the luciferase gene, pOLUC, was used as a promoterless control.
