ACVR2B and hepatocellular carcinoma: In a previous study, we identified a plasma miRNA panel for the diagnosis of hepatitis B‐related HCC in a cohort of 934 patients with CHB, cirrhosis and HBV‐related HCC using microarray technology.21 In this study, we expanded this work by exploring the role and mechanisms of miR‐194, one of six differentially expressed miRNAs in CHB, and its target ACVR2B in liver injury and regeneration associated with CHB.
