lncRNA PTENP1 can promote autophagy, as a sponge of miR-17, miR-19b, and miR-20a, by targeting ULK1, ATG7, p62, phosphatase and tensin homolog (PTEN), and PH domain and leucine-rich repeat protein phosphatase 1 (PHLPP), which could promote progression of hepatocellular carcinoma [33, 34]. The gene discussed is PTEN; the disease is hepatocellular carcinoma.
