Among them, YAP1 expression was upregulated in cholangiocarcinoma (CHOL), colon adenocarcinoma (COAD), and thyroid carcinoma (THCA), and was downregulated in bladder urothelial carcinoma (BLCA), breast invasive carcinoma (BRCA), head and neck squamous cell carcinoma (HNSC), kidney chromophobe (KICH), kidney renal clear cell carcinoma (KIRC), kidney renal papillary cell carcinoma (KIRP), lung adenocarcinoma (LUAD), lung squamous cell carcinoma (LUSC), pheochromocytoma and paraganglioma (PCPG), prostate adenocarcinoma (PRAD), and uterine corpus endometrial carcinoma (UCEC) (Figure 1A). This evidence concerns the gene YAP1 and squamous cell lung carcinoma.
