bcl-2 protein expression. (A) H pylori negative chronic gastritis: moderate bcl-2 expression. (B) H pylori positive chronic gastritis. (C) H pylori positive chronic gastritis with dysplasia: low bcl-2 expression. (D) H pylori positive chronic gastritis: moderate expression of bcl-2 protein in areas of intestinal metaplasia. (E) Nodal metastasis from gastric cancer: negative for bcl-2 protein in gastric cancer cells. Original magnifications: A, × 250; B, × 250; C, × 400; D, × 250; E, × 100.
