Differential gene expression analysis made through the GEPIA2 web server (http://gepia2.cancer-pku.cn/#index, accessed on 12 October 2021) confirms that P2RY2 is overexpressed in both colon (Log2foldchange TumorvsNormal = 0.996 with p = 3.26e−12) and rectal (Log2foldchange TumorvsNormal = 1.086 with p = 1.97e−9) adenocarcinomas when compared to their normal counterparts [75]. Here, P2RY2 is linked to adenocarcinoma.
