Inhibition of EGFR by erlotinib downregulates PTPMeg2 in association with activation of the STAT3/Bcl2/Bcl-XL pathway in lung cancer HCC827 cells. A, HCC827 cells were treated with increasing concentrations of erlotinib (Erlo) for 48h. pEGFR, PTPMeg2, pSTAT3, Bcl2, Bcl-XL, etc., were analyzed by Western blot. B, HCC827 cells were treated with erlotinib (0.1 μM) for various times. Levels of Bcl2 or Bcl-XL mRNA were analyzed by RT-PCR.
