In liver cancer, by degrading HNRNPA2B1 via ubiquitination, which reduces the stability of p52 and p65 mRNAs, and inhibiting the NF-κB signaling pathway in hepatocellular carcinoma cells, lncRNA miR503HG inhibits tumor metastasis [48]. The gene discussed is NFKB1; the disease is hepatocellular carcinoma.
