Analysis of POLR3G and POLR3GL expression levels in these data uncover significant increases in POLR3G gene expression bias in several primary solid tumors when compared to patient-matched normal tissues, including lung squamous cell carcinoma, lung adenocarcinoma, stomach adenocarcinoma, esophageal carcinoma, kidney chromophobe, cholangiocarcinoma, colorectal adenocarcinoma, bladder urothelial carcinoma, and uterine corpus endometrial carcinoma (Fig. 4a–j). Here, POLR3G is linked to lung adenocarcinoma.
