Regucalcin expression in bovine tissues and its regulation by sex steroid hormones in accessory sex glands.
Regucalcin (RGN) is a mammalian Ca2+-binding protein that plays an important role in intracellular Ca2+ homeostasis.Recently, RGN has been identified as a target gene for sex steroid hormones in the prostate glands and testis of rats and humans, but no studies have focused on RGN expression in bovine tissues.Thus, in the present study, we examined
