These observations are consistent with data showing that 1,25(OH)2D suppressed secretion of IL-8 by interfering with NFκB signaling in RWPE1 cells [31] and that it enhanced radiosensitivity of prostate cancer cells by selectively suppressing radiation-mediated RELB activation in prostate cancer cell lines [55]. The gene discussed is CXCL8; the disease is prostate cancer.
