    Article Snippet: The inhibitory role of RFRP-3 in the hypothalamic-pituitary axis is established, but its direct intra-ovarian actions remain poorly defined.. This study reveals, for the first time, the expression of RFRP-3 and its receptor GPR147 in ovarian granulosa cells of Tan sheep.. We demonstrate that RFRP-3 acts locally to suppress steroidogenesis by downregulating key steroidogenic enzymes (STAR, CYP19A1, HSD17B2).
