Vitamin D signaling regulates oral keratinocyte proliferation in vitro and in vivo

Abstract excerpt

The secosteroidal hormone 1,25-dihyroxyvitamin D [1,25(OH)(2)D(3)] and its receptor, the vitamin D receptor (VDR), are crucial regulators of epidermal proliferation and differentiation. However, the effects of 1,25(OH)(2)D(3)-directed signaling on oral keratinocyte pathophysiology have not been well studied. We examined the role of 1,25(OH)(2)D(3) in regulating proliferation and differentiation in cultured oral...
