Apoptosis by TUNEL and related Bax and Bcl-2 by immunohistochemistry in small intestinal adenocarcinomas. (A) Hematoxylin-eosin staining of one cancer case. (B) Apoptotic cells by TUNEL (red arrows indicate the representative apoptotic cells). (C) Bax was absent in most small intestinal cancers. (D) Bax was strong in a case of human small intestinal adenocarcinoma. (E) Bcl-2 was absent in most small intestinal adenocarcinomas. (F) Bcl-2 expression was strong in a case of small intestinal adenocarcinoma. Bars: A,B = 80 μm; C–F = 40 μm.
