EGFR and lung cancer: The occurrence and development of lung cancer are related to the imbalance of multiple signal pathways, such as the activation of PI3K/Akt/mTOR signaling pathway (Hao et al., 2019), CCR7(chemokine receptor7) (Pu et al., 2018), EGFR (Zhuo and Ji, 2017), and the high expression of TMEM16A (transmembrane protein 16A) (Guo et al., 2019).
