PTENP1 and hepatocellular carcinoma: Some research also indicates that the overexpressed PTENP1 in hepatocellular carcinoma (HCC) competitively binds with miR-17, miR-19b, and miR-20a to promote the ULK1, ARG7, and p62 autophagic genes to complete the autophagy process and to suppress HCC progression [19].
