Abstract:
AIM: To investigate the expression of adhesion molecules in hepatocellular carcinoma (HCC), and analyze its clinical significance. METHODS: The expression of adhesion molecules of tumor tissues of 64 cases and adjacent tissues of 12 cases of HCC were detected with RT-PCR. RESULTS: ①The expression rates of E-cadherin, ICAM-1 , CD44, CD 44V , ? 5, ? 1 were 90 62%, 93 75%, 50 00%, 96 88%, 100%, 100%, respectively, and there was a significant difference between CD44 and other adhesion molecules. ②The expression level of E-cadherin, ICAM-1, CD44, CD 44V , ? 5,? 1 in liver cancer tissues were 1 24?0 54, 0 96?0 37, 0 62?0 73, 0 86?0 33, 0 97?0 49, 1 41?0 24, respectively, and there was a significant difference between CD44 and E-cadherin, ? 1. ③The expression level of E-cadherin and CD44 mRNA declined as HCC stage become higher, and there was a statistical difference in the expression level of CD44 mRNA between Ⅰ-Ⅱ stage and Ⅳ stage. The expression level of ICAM-1, ? 5, ? 1 had a trend to rise as HCC stage become higher, and there was a statistical difference in the expression level of ICAM-1 between Ⅰ-Ⅱ stage and Ⅳ stage. ④The expression level of ICAM-1,CD 44V , ? 5, ? 1 had positive correlation with tumor volume, tumor nodules, tumor metastasis, and had negative correlation with tumor encapsulation. E-cadherin and CD44 had negative correlation with tumor volume, tumor nodules, tumor metastasis, and had positive correlation with tumor encapsulation. All showed no significant correlation with the level of AFP , the degree of cirrhosis and the function of liver. CONCLUSION: There was a significant difference in the expression level of adhesion molecule mRNA in HCC, and their expression had Spearman correlation with each other. The expression level of adhesion molecule mRNA is associated with tumor volume, tumor nodules and tumor metastasis. [
