Heatley MK, Corke K. Integrin expression in cervical carcinoma. Int J Gynecol Cancer 1998; 8: 203–206.
Integrin expression was studied in a series of 36 cervical carcinomas using antibodies to integrins αvβ5, α3, β1 and β4. Integrins αvβ5, α3 and β1 were localized to the cell membrane in well differentiated (0/13, 2/4 and 4/14 cases) and moderately differentiated adenocarcinomas (0/6, 1/5 and 1/6 cases, respectively) and in adenosquamous (2/6, 2/5 and 3/6) well differentiated (1/4, 0/3, and 3/5) and moderately differentiated (1/2, 1/3 and 1/3) squamous cell carcinomas. Two antibodies (AA3 and 439‐B) located integrin β4 to the cell membranes and cytoplasm of well (13/13 and 10/12 cases) and moderately differentiated (6/7 and 5/6 cases) adenocarcinomas, cases of adenosquamous carcinoma (6/6 and 5/6 cases), and well (4/4 and 3/4 cases) and moderately (3/3 and 3/4 cases) differentiated squamous cell carcinomas. In conclusion, integrin expression was identified most frequently with the antibodies to β4 which was localized to cervical carcinomas of varying grades and histological types. Immuno‐staining was identified less frequently with the antibodies to αvβ5, α3 and β1.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
