Abstract
The study aims to explore the biological function of SHC1 in the development and progression of lung cancer. Meanwhile, the effect of SHC1 and EGFR on lung cancer was analyzed. The expression of SHC1 in lung cancer and adjacent tissues was analyzed by bioinformatics and immunohistochemistry. Meanwhile, the relationship between SHC1 expression and prognosis was analyzed. SHC1 overexpression and knockdown cell lines were constructed by overexpression plasmid and knockdown plasmid. Cell proliferation was detected by CCK-8. Cell invasion was detected by transwell. Apoptosis was detected by TUNEL. Interaction between SHC1 and EGFR was detected. The expression of SHC1 in lung adenocarcinoma tissues was significantly higher than that in paracancer tissues. Lung cancer patients with high SHC1 expression have a poor prognosis. The proliferation and invasion of SHC1 decreased with SHC1 knockout but increased after overexpression. EGFR may be a key interaction protein of SHC1. Overexpression of EGFR increases the oncogenic effect of SHC1. In conclusion, SHC1 plays a carcinogenic role in lung cancer. EGFR expression was significantly correlated with SHC1 and maybe a key interaction protein of SHC1. SHC1 interacts with EGFR to form a protein complex, which may be a new target for lung cancer metastasis.
