Vitamin D receptors are widely expressed in the skeletal system, and vitamin D and its metabolites and analogs, exert a variety of biological activities such as regulation of cellular proliferation and differentiation, cell calcium transients and energy metabolism in vitro. The latter is exerted through the control of the brain type isozyme of creatine kinase specific activity (CK), which serves to provide a readily available reservoir for ATP generation under increased worklo...
