Abstract:
Objective To study the expression of RhoA protein in colorectal carcinoma. Methods The expression of RhoA protein in 92 cases of colorectal ccarcinoma and 30 cases of normal rectal tissue was detected by SP immunohistochemical technique. Results RhoA protein were negative in 40 cases of normal colorectal tissue. In 92 cases of colorectal carcinoma, the positive rate of RhoA protein was 70.7%. It was significantly higher than that in the normal colorectal tissue. The positive rate of RhoA protein in high-differentiated 、moderate-differentiated and lowdifferentiated rectal carcinoma were 43.5% 、74.4% and 86.7% ,respectively(P ＜0.05). The positive rates of RhoA in phase Ⅰ、phase Ⅱ、phase Ⅲ and phase Ⅳ were 48.6% 、77.3% 、83.3% and 94.1%, respectively (P ＜ 0.05).The positive rate of RhoA protein in patients with lymphnode mestastasis and non-lymphnode mestastasis were 82% and 57.1% (P ＜ 0.05). Conclusion RhoA protein could be related with the differentiation、invasion、metastatsis and prognosis of colorectal carcinoma.
