Apart from glioblastoma multiforme, kidney chromophobe and kidney renal clear cell carcinoma, analysis using the TIMER database revealed that TOMM34 expression was elevated in 13 TCGA tumors compared with normal tissues, including bladder urothelial carcinoma, breast invasive carcinoma, cholangiocarcinoma, colon cancer, esophageal carcinoma, head and neck squamous cell carcinoma, liver hepatocellular carcinoma, lung adenocarcinoma, lung squamous cell carcinoma, rectum adenocarcinoma, stomach adenocarcinoma, thyroid carcinoma and uterine corpus endometrial carcinoma (Figure 1B). This evidence concerns the gene TOMM34 and chromophobe renal cell carcinoma.
