Both proliferation and apoptosis are disrupted during carcinogenesis. Whether altered apoptosis contributes to this field change of microscopic abnormality is, however, unclear. Bcl-xL is an anti-apoptotic protein that inhibits apoptosis by preventing release of cytochrome\n                    <jats:italic>c<\/jats:italic>\n                    , a recognised pathway to cell death.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Aim:<\/jats:bold>\n                    To determine whether Bcl-xL inhibition of apoptosis is increased in colorectal mucosa adjacent to colorectal adenocarcinoma over that in normal non-neoplastic colorectal mucosa.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Patients:<\/jats:bold>\n                    Patients undergoing surgical resection for neoplastic (adenocarcinoma) or non-neoplastic disease of the colorectum (rectal prolapse, diverticular disease or volvulus).\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Methods:<\/jats:bold>\n                    Formalin-fixed, paraffin-wax-embedded surgical colorectal resection specimens were immunostained for Bcl-xL protein.

Bcl-xL immunostaining was most marked in the upper third of mucosal crypts. It occurred in a minority of samples from non-neoplastic colorectal mucosa, but was seen in most mucosal samples adjacent to colorectal adenocarcinoma. Significant increases (p&lt;0.001) were observed in Bcl-xL labelling indices in the mucosa at 1 cm (n\u200a=\u200a46, median labelling index 31.8%, interquartile range 8.3\u201343.9%) and at 10 cm (n\u200a=\u200a52, median labelling index 22.0%, interquartile range 0.0\u201336.3%) from colorectal carcinoma, compared with normal, non-neoplastic colorectal mucosa (n\u200a=\u200a22, median labelling index 0.0%, interquartile range 0.0\u20130.0%).\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusions:<\/jats:bold>\n                    The findings are consistent with a field change of inhibited apoptosis in mucosa adjacent to colorectal carcinoma.\n                  <\/jats:p>","DOI":"10.1136\/jcp.2005.033431","type":"journal-article","created":{"date-parts":[[2006,5,5]],"date-time":"2006-05-05T20:32:00Z","timestamp":1146861120000},"page":"942-946","source":"Crossref","is-referenced-by-count":16,"title":["A \u201cfield change\u201d of inhibited apoptosis occurs in colorectal mucosa adjacent to colorectal adenocarcinoma"],"prefix":"10.1136","volume":"59","author":[{"given":"S","family":"Badvie","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A","family":"Hanna-Morris","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H J N","family":"Andreyev","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P","family":"Cohen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S","family":"Saini","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T G","family":"Allen-Mersh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2006,5,5]]},"reference":[{"key":"2025092502084909000_59.9.942.1","doi-asserted-by":"crossref","unstructured":"Deschner EE.
