Expression of CDK4 and cyclin D1 proteins in gastric carcinoma / 上海第二医科大学学报

ABSTRACT

Objective To investigate the expression and significance of CDK4 and cyclin D1 in gastric carcinoma,and to discuss their correlation with WHO histological classification,TNM stages and lymph node metastasis.Methods Forty paraffin wax specimens from patients with gastric carcinoma were collected and expression of CDK4 and cyclin D1 proteins were detected by immunohistochemistry.Results Immunohistochemistry demonstrated that the positive rates for CDK4 and cyclin D1 protein were 65% and 55%,respectively.There was positive correlation between CDK4 and cyclin D1 proteins(P0.05).Conclusion CDK4 and cyclin D1 proteins are frequently overexpressed in gastric carcinoma and there is a positive relationship between the two proteins,which may be involved in the development of gastric carcinoma.
