The results suggested that the protein expression of USP13 is significantly elevated in tumor tissues compared with normal samples in pancreatic adenocarcinoma (PAAD), head and neck squamous carcinoma (HNSC), clear cell renal cell carcinoma (ccRCC) and uterine corpus endometrial carcinoma (UCEC) (Fig. 1C – F). The gene discussed is USP13; the disease is pancreatic adenocarcinoma.
