By overexpressing ARID2 in HCC cell lines (ARID2-Up), Duan et al. were able to suppress cell proliferation and migration in HCC cell lines, while downregulation of ARID2 by siRNA-mediated knockdown (ARID2-Kd) increased cell proliferation and migration capacities. This evidence concerns the gene ARID2 and hepatocellular carcinoma.
