In vivo functional assays presented that overexpression of LINC00467 markedly enhanced HCC xenograft growth and HCC cell proliferation and repressed HCC cell apoptosis in vivo, whereas knockdown of LINC00467 markedly repressed HCC xenograft growth and HCC cell proliferation and promoted HCC cell apoptosis in vivo. The gene discussed is LINC00467; the disease is hepatocellular carcinoma.
