Abstract:
Purpose To investigate the expression of the protein of Ezrin and AQP5 in the normal, dysplasia gastric and carcinoma of esophagogastirc junction tissues and to find out their relationship with the biologic behavior of the carcinoma of esophagogastirc junction in the southern area of Hebei Province. Methods Ezrin and AQP5 proteins were detected by immunohistochemical staining in 10 ca-ses of normal gastric tissue, 40 cases dysplasia and 165 cases of the carcinoma of esophagogastirc junction tissues, respectively. Re-sults All of the expression levels of Ezrin and AQP5 protein were increasing according to the order of normal-dysplsia-carcinoma. The expression rate of Ezrin was 10%, 45% and 72. 7%, while the rate of AQP5 with 20%, 32. 5% and 65. 5% in the normal, dysplasia and carcinoma subgroup. The expression rates of each protein were significantly different among the three groups (P<0. 05). The ex-pression of them in the subgroup of poorly-differentiated with serosa invasion and lymph nodes metastasis was significantly higher than the other subgroup of well-differentiated with non serosa invasion or lymph nodes metastasis (P<0. 05). There was a positive correla-tion between the expression of Ezrin and AQP5 proteins in the carcinoma of esophagogastirc junction (P<0. 05). Conclusions Over-expression of Ezrin and AQP5 is detected in the carcinoma of esophagogastirc junction, with positive relationships, which probably helps the invasiveness and metastasis in the carcinoma of esophagogastirc junction synergistically.
