Figure 3. Overexpression of TUG1 enhanced the apoptosis, autophagy and senescence of NSCLC cells in response to DDP. (A) the effect of TUG1 on the cell cycle distribution of NSCLC cells; (B) the effect of TUG1 on apoptosis of NSCLC cells; (C) GFP-LC fusion protein tagging detection of autophagosome formation; (D) MDC staining to detect formation of autophagic vacuoles; (E) expression of autophagy-related proteins and cell senescence-related protein hTERT determined by Western blot analysis, normalized to β-actin. ** p < 0.01 versus the control group.
