ABSTRACT
<p><b>OBJECTIVE</b>To detect the expression of skp2 and p27kip1 in human renal cell carcinoma (RCC) using tissue chip technique, and evaluate the relationship between the proteins and the biological behavior of RCC.</p><p><b>METHODS</b>Tissue chip technique and immunohistochemical SP method was used to detect the expression of skp2 and p27kip1 in normal and tumor tissues.</p><p><b>RESULTS</b>The positivity rate of Skp2 in RCC was significantly higher than that in normal renal tissues (P=0.025). The positivity rate of Skp2 expression in RCC was significantly correlated to poor differentiation of the tumor (P=0.002), and was not associated with the patients gender, age, tumor size, lymph node metastasis and stages of RCC (P>0.05). The positivity rate of p27kip1 in RCC was significantly lower than that in normal renal tissues (P=0.007). The positivity rate of p27kip1 expression was inversely correlated to the malignancy and stage of RCC (P<0.05), but not with the patients' age, gender, lymph node metastasis and tumor size (P>0.05). An inverse correlation was noted between Skp2 and p27kip1 expressions (r= -0.273, P=0.014).</p><p><b>CONCLUSION</b>Overexpression of Skp2 protein may lead to decreased p27kip1 level in RCC, indicating its involvement in the carcinogenesis and development of RCC.</p>
