Figure 1. — Upregulation of epidermal growth factor receptor (EGFR) in non-small cell lung carcinoma (NSCLC) tissues compared with normal tissues. (a) EGFR expression analysis based on TCGA dataset showed that EGFR mRNA levels were higher in lung cancerous tissues (NSCLC) than in matched normal adjacent tissues (NAT). (b) EGFR expression was correlated with the clinical stage of lung cancer. (c) Kaplan-Meier analysis of survival of patients with NSCLC. (d, e) Western blot analysis of the EGFR protein levels in 27 paired NSCLC and NAT samples. (d) Representative images. (e) Quantitative analysis; **p < 0.01.
