In doing so, elevated PSMA7 expression was confirmed in the cancers of bladder urothelial carcinoma (BLCA), breast invasive carcinoma (BRCA), cholangiocarcinoma (CHOL), COAD, esophageal carcinoma (ESCA), glioblastoma multiforme (GBM), head and neck squamous cell carcinoma (HNSC), LIHC, LUAD, LUSC, READ, stomach adenocarcinoma (STAD), UCEC, and cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC), prostate adenocarcinoma (PRAD), thyroid carcinoma (THCA), as compared with the matched control tissues (Fig. 3A). The gene discussed is PSMA7; the disease is head and neck squamous cell carcinoma.
