AGTR2 and neoplasm: Although there was no receptor significantly common to all four series, the angiotensin II type 2 receptor (AGTR2) was found to be downregulated in the tumor tissue in all the studies (GSE60459, log2FC = −1.1, p = 0.03; GSE50442, log2FC = −0.56, p = 0.493; GSE39716, log2FC = −0.75, p = 0.003; GSE19422, log2FC = −0.60, p = 0.003).
