In addition, it was found that lncRNA HULC plays a role as the ceRNA of miR-3200-5p in hepatocellular carcinoma, and miR-3200-5p can regulate the ferroptosis process by targeting ATF4 and inhibit the proliferation and metastasis of hepatoma cells (Guan et al., 2022). The gene discussed is ATF4; the disease is hepatocellular carcinoma.
