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.
