1α,25(OH)D Radiosensitizes Cancer Cells by Activating the NADPH/ROS Pathway.

The radioresistance of tumors affect the outcome of radiotherapy. Accumulating data suggest that 1α,25(OH)D is a potential anti-oncogenic molecule in various cancers. In the present study, we investigated the radiosensitive effects and underlying mechanisms of 1α,25(OH)D and .
