The miR-1247-3p in hepatocellular carcinoma cell (HCC)-derived exosomes targets β-1,4-galactosyltransferases III in fibroblasts and activates β1-integrin-NF-κB signalling, leading to liver cancer progression and lung metastasis [121]. The gene discussed is NFKB1; the disease is hepatocellular carcinoma.
