Immunohistochemical analysis of pSTAT3 and SOCS3 protein expression and in situ hybridization analysis of pSTAT3 mRNA expression in hepatocellular carcinoma (HCC) and adjacent non-tumor tissue. (A) pSTAT3 protein expression in HCC; (B) pSTAT3 protein expression in non-tumor tissue; (C) SOCS3 protein expression in HCC; (D) SOCS3 protein expression in non-tumor tissue; (E) STAT3 mRNA expression in HCC; (F) STAT3 mRNA expression in non-tumor tissue. All images were counterstained with hematoxylin. Original magnification, x400.
