Abstract

AbstractThe Bin1/Amphiphysin II gene encodes at least seven alternately spliced adapter proteins that have been implicated in membrane dynamics and nuclear processes. Nuclear localized Bin1 polypeptides have tumor suppressor and proapoptotic activities, suggesting that Bin1 may suppress cancer in tissues where nuclear expression may occur. One question is the extent to which human tissues express nuclear Bin1 isoforms. A secondary issue has been the need for a specific antibody that can detect all the splice isoforms expressed by the human, mouse, and rat Bin1 genes. Using a novel mouse monoclonal antibody with these characteristics, we performed an immunohistochemical analysis of Bin1 expression in a panel of normal human tissues. We also compared the expression profile of Bin1 in normal or malignant tissues derived from human prostate, where Bin1 is a candidate tumor suppressor gene. In brain, a distinct nuclear staining pattern overlapped with a cytosolic staining pattern present in certain layers of the cerebral cortex and cerebellum. Bone marrow cells displayed mainly nuclear localization whereas peripheral lymphoid cells exhibited mainly cytosolic localization. In several epithelial tissues, nuclear or nucleocytosolic staining patterns were displayed by basal cells in skin, breast, or prostate, whereas cytosolic or plasma membrane‐associated staining patterns were noted in gastrointestinal cells. Interestingly, a striking gradient of expression was observed in gastrointestinal epithelia, particularly in the large intestine, with the strongest staining displayed by cells destined to undergo apoptosis at the villus tip. In prostate, Bin1 staining was frequently absent in cases of primary prostate adenocarcinoma. This study used a novel reagent to document the extent of expression of nuclear Bin1 isoforms, which exhibit cancer suppression and proapoptotic activity in human cells. © 2002 Wiley‐Liss, Inc.
