Assessment of apoptosis in vitro. The efficacy of inducing A549 cell apoptosis in vitro was evaluated by flow cytometry and TUNEL assays. (A) Flow cytometry quantitation revealed that Lip-phTERT-M resulted in the highest apoptotic rate of A549 cells. (B) TUNEL assays showed that Lip-phTERT-M and Lip-pVAX-M increased the apoptotic index (AI) compared with the other groups (*P<0.05). However, Lip-phTERT-M resulted in a larger increase in AI compared with Lip-pVAX-M (*P<0.05). Data represent the mean AI ± SD of cancer cells.
