CYP2C9 and hepatocellular carcinoma: Most importantly, this study revealed an up-regulation of hsa-miR-128-3p expression and a significant inverse correlation between CYP2C9 expression and hsa-miR-128-3p expression in HCC tissues, indicating that hsa-miR-128-3p combined with CYP2C9 are potential biomarkers for HCC diagnosis.
