Abstract 37: Role and regulation of CYP24A1 in endometrial cancer
The cytochrome P450 enzyme, 24-hydroxylase, encoded by CYP24A1 is critical for the catabolism of 1,25(OH)2D3 (calcitriol). The unbalanced high levels of CYP24A1 seem to be a determinant of calcitriol resistance in tumors. We have previously shown that progesterone enhances calcitriol antitumor activity by upregulating vitamin D receptor expression and promoting apoptosis in endometrial cancer cells. In the present study, we evaluated CYP24A1 protein expression in normal and endometrial tumor tissues, assessed the effect of progesterone and calcitriol on CYP24A1 and its spliced variant expression in endometrial cancer cell ...
