To further explore the mRNA expression level of NCBP2 in hepatocellular carcinoma, we performed a verification to investigate the differential mRNA expression between HCC tumor samples and adjacent normal samples in the GEPIA2 (http://gepia2.cancer-pku.cn/) (accessed on 1 March 2021) and TIMER databases (https://cistrome.shinyapps.io/timer/) (accessed on 1 March 2021). This evidence concerns the gene NCBP2 and hepatocellular carcinoma.
