Objective To investigate the significance of overexpression of p5s and bcl-2 protein in carcinogene- sis of cervix. Methods 10 cases of cervical intraepithelial neoplasis(CIN) and 57 cases of invasive cancer were in- vestigated with immunohistochemistry technique. Results The overexpresion or P53 protein ir CIN and cervical can- cer was significantly higher than that or control, respectively (P<0.01). But there was no significant difference be- tween CIN and cervical cancer(P>0.05). The immunoreactivity of bcl-2 in CIN was much more higher than that of control (P<0.05). The positive rate and immunoreactivity of bcl-2 in cervical carcinoma were both remarkably high- er than those of control (P<0.0l),but there was no significant difference between CIN and cervical carcinoma (P> 0.05). It was also found that there was a remarkably positive correlation between the overexpression of bcl-2 and P53 (P<0.01). Conclusion Because of the loss of wtP53 function,the expression of bcl-2 can not be down-reguated, which is associated with the pathogenesis and development of cervical carcinoma.
