TGFA is highly expressed in tumor tissues such as bladder cancer, oral cancer, pancreatic cancer, and small cell lung cancer, accelerating cell proliferation, invasion, and EMT (epithelial–mesenchymal transition), and is closely related to the prognosis of tumor patients (Kang et al., 2005; Liu et al., 2017; Hao et al., 2018; Zhang et al., 2021). This evidence concerns the gene TGFA and lip and oral cavity carcinoma.
