Description

Secalciferol (24,25-DIHYDROXYVITAMIN D 3/24R,25(OH)(2)D(3)) is suggested to be an essential hormone for the process of bone fracture healing, it has a physiological role in human bone and mineral metabolism, leading to an enhancement of osteocalcin synthesis. Secalciferol is possibly to bind a nuclear protein vitamin D receptor (VDR) to the ligand binding domain, which is stereo-specific for Secalciferol. The downstream effect will be triggered after the binding, including the inhibition of calcium channel to regulate the calcium homeostasis, and the following reduction of p53 and Pi-induced cytochrome C translocation

Treatment with 24R,25(OH)(2)D(3) (SECALCIFEROL) reduced Chondrogenic ATDC5 cell number and increased alkaline phosphatase specific activity in a dose-dependent manner. Moreover, 24R,25(OH)(2)D(3) reversed the Pi-induced decrease in incorporation of [(3)H]-thymidine and [(35)S]-sulfate incorporation, as well as the Pi-induced increase in apoptosis. These results suggest that Pi acts as an early chondrogenic differentiation factor, inducing response to 24R,25(OH)(2)D(3); treatment of committed chondrocytes with Pi induces apoptosis, but 24R,25(OH)(2)D(3) mitigates these effects, indicating a possible inhibitory feedback loop.
