Radiation therapy targets cancer cell death by overwhelming cells with harmful DNA damage. Understanding how cells repair radiation damage and in particular how they become resistant to radiation therapy is important for effective cancer treatment. Our lab made the novel discovery that Bcl10, a cytoplasmic protein important for NF-B activation, localizes to endogenous H2AX foci in the nucleus of breast cancer cells. We determined that following radiation treatment Bcl10 is recruited to ionizing radiation-induced foci in a dose-dependent matter and that it is important for the repair of radiation-induced DNA damage. We also observed that breast cancer cells are extremely sensitive to Bcl10 knockdown, causing cellular senescence, while normal breast epithelial cells are insensitive. Our findings identify Bcl10 as potent anti-cancer target. / Experimental Oncology
