Estrogen-Mediated Regulation of Fam3d in Mouse Uterus During the Estrous Cycle.

ABSTRACT: In mice, the uterus undergoes dynamic changes regulated by estrogen and progesterone during the estrous cycle. Proper regulation of these changes is critical for successful pregnancy. The Family with sequence similarity 3 (Fam3) gene family, comprising Fam3a, Fam3b, Fam3c, and Fam3d, encodes cytokine-like proteins, but their uterine roles remain unclear. This study examined Fam3 expression in the mouse uterus across the estrous cycle and assessed estrogen-dependent regulation. RNA-seq analysis revealed increased Fam3b, Fam3c, and Fam3d expression during proestrus and estrus. Notably, Fam3d showed dynamic regulation, peaking in these stages. To test estrogen regulation, estradiol was administered to ovariectomized mice, showing maximal
