Silencing hTERT attenuates cancer stem cell-like characteristics and radioresistance in the radioresistant nasopharyngeal carcinoma cell line CNE-2R

Figure 6. hTERT silencing could induce apoptosis in vivo. (A) Apoptotic cells in tumors detected by TUNEL, red fluorescence (TMR red) represents positive apoptotic cell nucleus, while blue fluorescence (DAPI) was used for nuclear localization (200×); (B) Histogram of the apoptosis index in each group (* indicates P<0.05 compared with the hTERT-shRNA group, and ** indicates P<0.01 compared with the hTERT-shRNA group).
