[Expression of bcl-2, c-erbB2, and p53 protein in cervical epithelial carcinogenesis].

Background & Objective: Less research of molecular biology have been reported on cervical carcinogenesis. So the authors designed this study to evaluate the expression and clinical significance of antiapoptosis gene bcl-2, oncogene c-erbB2, and tumor suppressor gene p53 in the progression of this kind of cancer.

Methods: Using S-P immunohistochemical technique, the authors examined the expression of bcl-2, c-erbB2, and p53 in 48 squamous cell carcinoma of the cervix, 42 cervical intraepithelial neoplasia (CIN), and 20 normal cervical tissues.
