Vitamin D metabolites modulate creatine kinase specific activity (CK) in cultured skeletal cells. In this study we assess the effect of vitamin D metabolites on CK in rat epiphyseal cartilage (Ep) and diaphyseal bone (Di). Female or male Wistar- derived rats were used either as intact or after gonadectomy (Ovx or cast respectively), and treatments started 2 weeks post surgery. Rats were injected daily for 1, 2 or 8 weeks with the less-calcemic vitamin D analogs CB 1093 (CB), J...
