title: Evidence for the regulation of 3 beta-hydroxysteroid dehydrogenase messenger RNA by human chorionic gonadotrophin in luteinized porcine granulosa cells.
abstract: The effects of hCG on the abundance of messenger RNA for the steroidogenic enzyme 3 beta-hydroxysteroid dehydrogenase (3 beta-OHSD) were studied in luteinized porcine granulosa cells. There were dose-dependent increases in the mRNA for this enzyme after 8 h incubation with hCG or dibutyryl cAMP. The results suggest that LH-like hormones regulate the expression of the 3 beta-OHSD gene in luteinized tissue, and this genomic regulation is a component of the luteotrophic regulation of steroidogenesis in the ovary.
