摘要
The effects of hCG on the abundance of messenger RNA for the steroidogenic enzyme 3β-hydroxysteroid dehydrogenase (3β-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 3β-OHSD gene in luteinized tissue, and this genomic regulation is a component of the luteotrophic regulation of steroidogenesis in the ovary. © 1990 by The Endocrine Society.
