Objective To investigate the expression of JAB 1 andβ-catenin in colorectal carcinoma and its biological behavior relation-ships by detecting colorectal cancer and corresponding paracancer tissue .Methods We used immunohistochemistry ( SP method ) to detect the expression of JAB1 andβ-catenin in 94 cases of colorectal cancer and corresponding paracancer tissues .The relationship be-tween JAB1 and β-catenin expression and development ,degree of differentiation ,clinical stage ,lymph node metastasis and prognosis of the colorectal cancer were analyzed .Results The expression of JAB1 in colorectal cancer rate was significantly higher than correspond-ing paracancer cancer tissues (χ2 =86.686,P<0.001).The positive expression rate of JAB1 in poorly differentiated colorectal cancer (94.3 %) was higher than that in highly differentiated colorectal cancer (79.7%%) (χ2 =5.634,P =0.018).JAB1 expression in lymph node positive cases (94.6 %) was higher than that in lymph node negative cases (73.7%) (χ2 =8.344,P=0.004).The positive expression rate in Dukes stage C +D period (93.2%) was significant different from that in the A +B period (70.0%) (χ2=8.124,P=0.004);The correlation between the expression of JAB1 and sex,age,tumor size was not statistically significant (P>0.05).In 94 cases colorectal cancer ,the number of abnormal expression of β-catenin was 61 cases(64.9%),significantly different from that of corresponding paracancer tissues ,26 cases(27.7%) (χ2 =26.209,P<0.001).The abnormal expression rate of β-catenin in poorly differentiated colorectal cancer (91.4 %) was higher than that in well differentiated colorectal cancer (72.9%) (χ2 =4.686,P=0.030).The abnormal expression rate of lymph node positive cases (98.2%) was higher than that of lymph node negative cases (76.3%)(P=0.001).The abnormal expression rate in Dukes stage C +D period (90.9% ) was signifantly different from that in stage A +B period (64.0%)(χ2 =9.454,P=0.002).The correlation between the expression of β-catenin and sex,age, tumor size was not statistically significant (P>0.05).Conclusions JAB1,β-catenin were involved in the incidence and development of colorectal cancer .JAB1 could be a new tumor marker for colorectal cancer to improve the rate of diagnosis .
