Fig. 5From: Heregulin-1ß and HER3 in hepatocellular carcinoma: status and regulation by insulinAssociation of HER3 to IR in HCC cells. a Hep3B and HepG2 cells were analyzed for HER3 and IR expression by immunofluorescence. b Whole-cell lysates from HCC cells were immunoprecipitated with a HER3 antibody and analyzed by Western blot using an anti-IR antibody. In parallel, negative controls were performed by immunoprecipitating the same lysates with a rabbit IgG. Pictures and blots are representative of two independent experimentsBack to article page
