The realization of the biological effects of vitamin D in cells is closely related to the functioning of the vitamin D-endo/para/autocrine system, which includes (1) photoconversion of 7-dehydrocholesterol in the skin with the formation of cholecalciferol; (2) synthesis of 25OHD (calcidiol) in the liver by means of two key vitamin D 25-hydroxylases (cytochromes P450), CYP2R1 and CYP27A1; (3) conversion of 25-hydroxyvitamin D (25OHD) in the kidneys or extrarenal tissues to hormonally active form, 1[alpha],25[(OH).sub.2]D, by 25OH-1[alpha]-hydroxylase (CYP27B1); (4) calcitriol transport to target organs by vitamin D binding protein (VDBP); and (5) binding of 1[alpha],25[(OH).sub.2]D to vitamin D receptors (VDR) and regulation of gene expression [7].
