Active vitamin D (1,25(OH)2D) has been shown to regulate numerous cell processes in mammary cells. Degradation of 1,25(OH)2D is initiated by the mitochondrial enzyme, 25-hydroxyvitamin D 24-hydroxylase (CYP24 A1), and provides local control of 1,25(OH)2D bioactivity. Several reports of the association
