Immunostaining of p-STAT3 and Ki67 in the non-NGM of patients with early GC. (A) Immunohistochemical localization of p-STAT3 in the non-NGM of patients with early GC positive and negative for SOCS3 methylation. (B) Comparison of p-STAT3 labeling index between negative and positive groups for SOCS3 methylation. (C) Immunohistochemical localization of Ki67 in non-NGM of patients with early GC positive and negative for SOCS3 methylation. (D) Comparison of Ki67 labeling index between negative and positive groups for SOCS3 methylation. p-, phosphorylated; STAT3, signal transducer and activator of transcription 3; non-NGM, non-neoplastic gastric mucosa; GC, gastric cancer; SOCS3, suppressor of cytokine signaling 3.
