POLR3G and neoplasm: Gene module analysis revealed that POLR3G expression was negatively correlated with tumor purity (cor = −0.178, P = 6.02e −04) and positively correlated with infiltrating levels of CD8+ T cell (cor = 0.317, P = 5.70e −10), neutrophil cells (cor = 0.237, P = 5.12e −06), and dendritic cells (cor = 0.399, P = 2.15e−15) in TCC (Fig. 5B).
