IGF2BP2 and hepatocellular carcinoma: Representative examples of the weak p62/IMP2 stain pattern of adjacent normal tissue and strong p62/IMP2 stain pattern of HCC tissue are shown in Figure 1B. In addition, western blotting analysis was performed to examine p62/IMP2 protein expression in the non-tumorigenic liver cell line L02 and five liver cancer cell lines.
