[Abstract]:Objective to investigate the expression of Wnt signaling pathway and integrin signal pathway in (LST) and their relationship with endoscopic morphology in colorectal lateral developing tumors, in order to understand the mechanism of the special growth pattern of LST. Methods 52 cases of LST diagnosed from January 1, 2010 to June 10, 2015 in Xiangya Hospital of Central South University were randomly selected. According to endoscopic morphology, 37 cases of mixed nodular type, 6 cases of granular homogeneous type, 5 cases of flat bulge type and 4 cases of pseudoconcave type were selected. The expression of 尾-catenin, phosphorylated GSK-3 尾 in Wnt signaling pathway and Paxillin,ILK in integrin signaling pathway in 52 cases of LST and 15 cases of protuberant adenoma in control group were detected by immunohistochemical method. The relationship between the expression of 尾-catenin, phosphorylated GSK-3 尾, Paxillin,ILK in LST and endoscopic morphology was analyzed by statistical method. Results the expression of 尾-catenin in LST was higher than that in PA (P0.05), the expression of 尾-catenin, phosphorylated GSK-3 尾 and Paxillin,ILK in LST was higher than that in PA (P0.05). The expression of 尾-catenin, phosphorylated GSK-3 尾 and ILK, in LST was correlated (P0.05), but not in PA (P0.05). Conclusion the pseudoconcave type of LST may have a special mechanism different from other endoscopes, and ILK may play a role in up-regulation of Wnt signaling pathway in LST.
