Objective:To investigate the expressions of P27kipl (P27) protein and cyclin E protein in human renal cell carcinoma and in paracarcinoma kidney cortex tissue
and to explore the correlation of these protein expressions with biological behavior of tumors.Methods:P27 and cyclin E expressions were studied in formalin-fixed
paraffin-embedded sections of renal cell carcinoma and in paracarcinoma kidney cortex tissue by means of a specific and sensitive immunohistochemical S-P assay.Results:The positive rates of P27 protein and cyclin E protein in renal cell carcinoma were significantly higher than those in paracarcinoma kidney cortex tissues ( P <0.01)
and P27 and cyclin E were concurrently expressed in RCC.There was an inverse relationship between the expression rate of P27 and the histological tumor grades ( P <0.01)
and the same with cyclin E.Conclusion:P27 and cyclin E expression rates are negatively correlated with the malignant degree of RCC
indicating that P27 and cyclin E might be a useful prognostic marker for renal cell carcinoma.
