Cortisol in vivo increases FSH beta mRNA selectively in pituitaries of male rats

Cortisol in vivo increases FSH beta mRNA selectively in pituitaries of male rats

Endocrinology 129(5): 2793-2795

Cortisol treatment for 6 or 12 days had no effect on serum FSH in intact males and animals castrated for 1 or 7 days, but pituitary FSH was increased by the steroid in both intact and castrate groups. In contrast, cortisol inhibited serum LH in both intact and castrated animals while only increasing pituitary levels of LH on 7 day castrates. Cortisol also increased the mRNA for FSH.beta. without affecting .alpha. or LH.beta. mRNAs. These data suggest that the selective increase in pituitary content of FSH may be due to a selective increase in FSH.beta. mRNA following exposure to cortisol.
