MAPK10 and hepatocellular carcinoma: The subcellular localization of MAPK10 was examined by indirect immunofluorescence staining, which indicated that Flag-tagged MAPK10 was localized in the nucleus after the transfection into HCC cells (Fig. 6A) and the western blot detection of MAPK10 protein expression also confirmed the success of transfection (Figs. 6B and 6C).
