Stable H358-shKLF4 and H1299-shKLF4 cells were transfected with a Rictor expression construct and KLF4, Rictor, mesenchymal and epithelial markers were examined by Western blotting with specific antibodies. β-actin was as a loading control. F and G , knockdown of KLF4 impedes mTOR/Rictor interaction in NSCLC cells. H358-shGFP, H358-shKLF4, H1299-shGFP and H1299-shKLF4 cells were lysed and immunoprecipitated with a Rictor, mTOR, or normal IgG antibody. The immune complexes and input were analyzed by immunoblotting with an mTOR (F) or Rictor (G) antibody.
