For instance, PVT1 promotes cancer progression in gallbladder cancer (Chen et al., 2019); NORAD promotes cell proliferation, invasion, and migration and inhibits apoptosis in lung cancer (Li et al., 2020); and MFI2-AS1 promotes cancer progression and metastasis in hepatocellular carcinoma (Wei et al., 2020). Here, NORAD is linked to cancer.
