Abstract
AIM: To detect the expression of RhoC and IQGAP1 proteins in hepatocellular carcinoma (HCC) and to analyze their clinicopathological significance.
METHODS: The expression of RhoC and IQGAP1 proteins was detected by immunohistochemistry in 56 HCC specimens and 15 normal liver specimens. The association of RhoC and IQGAP1 protein expression with clinicopathologicalparamters was analyzed.
RESULTS: The positive rates of RhoC and IQGAP1 expression were significantly higher in HCC than in normal liver tissue (66% vs 20%; 75% vs 13%, both P < 0.05). The expression of RhoC and IQGAP1 proteins was related to tumor differentiation and invasion in HCC (both P < 0.05). A positive correlation was noted between the expression of RhoC and that of IQGAP1 in HCC(r = 0.631, P < 0.05).
CONCLUSION: RhoC and IQGAP1 play significant roles in promoting the progression of HCC. Expression of RhoC and IQGAP1 can be used as useful parameters for clinical assessment of biological behavior and prognosis of HCC.
