VDR and ovarian cancer: Vitamin D stimulated the expression of VDR and reduced the metastatic potential of ovarian cancer cells by increasing E-cadherin and decreasing the expression of β-catenin both in vivo and in vitro [83], while, in OVCAR-3 and SKOV-3 ovarian cancer cells, calcitriol showed antiproliferative effects with an additive effect with celecoxib [84].
