Abstract:
Objective To study the expression and tsignificance of Cyclin D1, CDK4 and the levels of phosphorylated pRb in cervical carcinoma in Xinjiang Uigur Women. Methods The expression of Cyclin D1,CDK4 protein and phosphorylation status of pRb were detected by immunohistochemistry in 64 cervical carcinoma tissues and 43 normal cervical tissues. Results In cervical carcinomas, the positive rate of Cyclin D1 and CDK4 were 70% and 87%, respectively. There were significant differences of CyclinD1 and CDK4 protein compared with normal cervical tissues(
P<0.01). Phosphorylation status of pRb had significant difference in the two groups (
P<0.01). Conclusion The overexpression of Cyclin D1 and CDK4 and the hyperphosphorylation of pRb may have relationship with carcinogenesis and the development of cervical cancer in Xinjiang Uigur Women.
