As shown in Figure 1A, the expression level of TWF1 in the tumor tissues of BRCA, CHOL (Cholangiocarcinoma), ESCA (Esophageal carcinoma), GBM (Glioblastoma Multiforme), KICH (Kidney Chromophobe), LIHC, LUAD, LUSC (Lung squamous cell carcinoma), STAD (Stomach adenocarcinoma), THCA, UCEC (Uterine Corpus Endometrial carcinoma) (P<0.001), HNSC (Head and Neck squamous cell carcinoma) (P<0.01), CESC (Cervical squamous cell carcinoma and Endocervical adenocarcinoma), COAD (Colon adenocarcinoma), KIRP (Kidney Renal Papillary Cell carcinoma) (P<0.05) is higher than the corresponding control tissues. This evidence concerns the gene TWF1 and squamous cell lung carcinoma.
