Expression of Ki-67, PCNA and P21 protein in GES-1 cells. A: Ki67 antigen was mostly located in the nuclei of GES-1 cells. The intensity of Ki67 was higher in the H. pylori 30 group (A2) than in the control group (A1) and H.pylori group (A3). B: PCNA antigen was mostly located in the nuclei of GES-1 cells; The intensity of PCNA was higher in the H. pylori 30 group (B2) than in the control group (B1) and H. pylori group (B3). (C) Expression of P21 was mostly located in the cytoplasm of GES-1 cells; the expression intensity of P21 was lower in the H. pylori 30 group (C2) than in the control group (C1) and H. pylori group (C3) (Immunohistochemical staining × 200).
