Mus musculus | the luteinizing hormone induces the enzyme. MA-10 cell stimulation with either human chorionic gonadotropin or uncarboxylated-osteocalcin increases CYP2R1 protein expression in a dose-dependent manner and, in turn, increases the release of 25-hydroxy-vitamin D in culture medium. Osteocalcin, in particular uncarboxylated osteocalcin, stimulates 25-hydroxylation of vitamin D in Leydig cells through a direct effect on the expression of the main actor in the 25-hydroxylase activity of vitamin D, the CYP2R1 protein | up |

metabolism | the cross talk from the bone to the testis of the vitamin D 25-hydroxylase CYP2R1 involves osteocalcin, which is produced by the osteoblasts and stimulates the production of testosterone by the Leydig cells through its putative receptor GPRC6A, a cation-sensing G-protein-coupled receptor.
