EGF and non-small cell lung carcinoma: On the other hand, stimulation of human NSCLC cells with exogenous EGF (Figure S7a,b, Supporting Information) or transfecting the cells with EGFR‐overexpressing plasmids (Figure S7c,d, Supporting Information) or the EGFR‐19del virus (Figure S7e,f, Supporting Information) enhanced the EGFR phosphorylation (Tyr1068) and CD73 expression.
