Because we lack a CPEB4 antibody with good specificity for immunohistochemistry, we determined CPEB4 protein level in primary tumorous (T) and adjacent non-tumorous (N) liver tissues from 49 HCC patients by using immuoblotting with our CPEB4 monoclonal antibody (Fig 5A). This evidence concerns the gene CPEB4 and hepatocellular carcinoma.
