The results showed that GNG7 expression was significantly down-regulated in 17 different tumors, including Bladder Urothelial Carcinoma (BLCA), Breast invasive carcinoma (BRCA), Colon adenocarcinoma (COAD), Lung adenocarcinoma (LUAD) while it was significantly up-regulated in Cholangiocarcinoma (CHOL), Liver hepatocellular carcinoma (LIHC) and Pheochromocytoma and Paraganglioma (PCPG) (Figure 2C). Here, GNG7 is linked to bladder transitional cell carcinoma.
