Abstract
14-3-3¥æ is related to many cancer survival cellular processes. In a previous study, we showed that silencing 14-3-3¥æ decreases the resistance of hepatocellular carcinoma (HCC) to chemotherapy. In this study, we investigated whether silencing 14-3-3¥æ affects the radioresistance of cancer stem-like cells (CSCs) in HCC. Knockdown of 14-3-3¥æ decreased cell viability and the number of spheres by reducing radioresistance in CSCs after ¥ã-irradiation (IR). Furthermore, the levels of pro-apoptotic proteins were upregulated in CSCs via silencing 14-3-3¥æ after IR. These results suggest that 14-3-3¥æ knockdown enhances radio-induced apoptosis by reducing radioresistance in liver CSCs.
