Expression of pSTAT3 and SOCS3 in PDAC and matched pericancerous tissue. a The representative images of immunohistochemistry staining of IL-6, pSTAT3, DNMT1, DNMT3a and SOCS3 in one matched PDAC (T) and pericancerous tissue (P) (20 × objective). b Statistical analysis of the IHC scores for the expression of IL-6, pSTAT3, DNMT1, DNMT3a and SOCS3 in the five pairs of PDAC and pericancerous tissue. c Protein expression levels of pSTAT3, STAT3 and SOCS3 were examined in five pairs of PDACs (T) and their matched pericancerous tissues (P) using western blots. d Protein expression levels of pSTAT3, STAT3 and SOCS3 were analyzed in nine pancreatic cancer cell lines using western blots
