LC3II and LC3I levels in PC9 cells and erlotinib resistant PC9 cells.

<p>* (A) Autophagy levels were assessed by western blot for LC3II and p62. (B) ERPC9 cells had significantly higher levels of LC3II than in PC9 cells (p = 0.030) and significantly lower levels of p62 than in PC9 cells (p<0.0001); indicating higher baseline autophagy levels in erlotinib resistance cells. Concordantly, it can be seen that there were significantly lower levels of LC3I in ERPC9 cells compared to PC9 cells (p = 0.008).
