✦ Synopsis
APO-I is a 48-kDa cell-membrane protein identical to the Far antigen now designated CD95. It is a member of the NGF/TNF receptor superfamily. Anti-APO-I monoclonal antibody induces apoptosis in a variety of cell types expressing this antigen. We immunohistochemically investigated APO-I expression in normal colon mucosa, 20 adenomas, 258 colon carcinomas and I0 liver metastases and carried out in vitro studies using a panel of colon-carcinoma cell lines. lmmunohistochemically, APO-I was regularly expressed at the basolateral membrane of normal colon epithelia. In a minor fraction of colon adenomas and in 4To whom correspondence and reprint requests should be sent, at
