The protein expressions of HER2, p-HER2, SOCS3, STAT3 and p-STAT3.
Note: (A) Western blotting detected the protein expressions of HER2, p-HER2, SOCS3, STAT3 and p-STAT3; (B) relative protein expression levels of HER2, p-HER2, SOCS3, STAT3 and p-STAT3; HER2, human epidermal growth factor receptor 2; p-HER2, phosphorylated HER2; SOCS3, suppressors of cytokine signaling 3; STAT3, signal transducer and activator of transcription 3; p-STAT3, phosphorylated STAT3; *, P < 0.05 compared with the adjacent normal tissues.
