As we have shown in the previous sections, mortalin promoted the migration and invasion of hepatocellular carcinoma cells via RECK/STAT3 signaling, and Sal B inhibited EMT, the RECK/STAT3 pathway, MMP9/MMP2, and the migration and invasion of hepatocellular carcinoma cells. The gene discussed is MMP2; the disease is hepatocellular carcinoma.
