HLA-DQB1 and hepatocellular carcinoma: Our study not only innovatively demonstrates the oncogenic roles of HLA-DQB1-AS1 and ZRANB2 in hepatocellular carcinoma but also innovatively identifies the interaction between HLA-DQB1-AS1 and ZRANB2 protein, which enriches the molecular mechanism of the pathogenesis of hepatocellular carcinoma.
