Effect of 25(OH)D on the small RNA expression of breast cancer cell MDA-MB-453


ABSTRACT: Vitamin D is a pro-hormone that possesses various anticancer effects through diverse mechanisms. The enzyme vitamin D-25-hydroxylase can convert vitamin D into 25-hydroxyvitamin D (25(OH)D) in the liver. 25(OH)D serves as the precursor of 1,25-dihydroxyvitamin D (1,25(OH)2D or calcitriol), which can be transformed into 1,25(OH)2D by the enzyme CYP27B1. CYP27B1 is primarily distributed in the kidneys but can also be found in other tissues, such as the breast and colon. Although 1,25-dihydroxyvitamin D has been the primary object of in vitro studies, emerging evidence suggests that 25(OH)D can also generate anticancer effects by transforming into 1,25(OH)2D in the manner of autocrine and paracrine. Our study aims to investigate the impact of 25(OH)D on breast cancer and its effect on the expression of small RNA in breast cancer cells cultured with 100nM 25(OH)D.
