MTOR and non-small cell lung carcinoma: Studies have shown that Akt and Erk pathways, as a key signaling pathway regulating cell proliferation, migration, and EMT progress, can be significantly activated in NSCLC.16, 17 Thus, we performed the western blotting to detect the protein levels of the Akt and Erk signaling pathways relative genes, P70, p‐Akt, p‐mTOR, and p‐Erk.
