Abstract
Purpose To explore the expression,significance and relationship of apoptosis related gene Apollon and Caspase 9 in gastric carcinoma. Methods The SP immunohistochemical method was used to detect the expression of Apollon and Caspase 9 in 105 cases of gastric carcinoma,38 adjacent tissues and 29 normal tissues,and the expression of Apollon and Caspase 9 was analyzed with relation to clinicopathologic factors. Results The numbers of positive expression of Apollon gene in gastric carcinoma tissues,adjacent tissues and normal tissues were 82(78. 10％) ,8(21. 05％) and 2(6. 90％) respectively, there was significant difference between gastric carcinoma tissues, adjacent tissues and normal tissues (P < 0. 01) . The expression of Apollon in gastric carcinoma was positively correlated with degree of tumor differentiation,TNM staging and lymph node metastasis (P < 0. 05) ,but not with other clinicopathologic factors (P > 0. 05) . The numbers of positive expression of Caspase 9 gene in gastric carcinoma tissues,adjacent tissues and normal tissues were 21 (20. 00％) ,23 (60. 53％) and 21 (72. 41％) ,respectively,and there was significant difference between gastric carcinoma tissues,adjacent tissues and normal tissues (P < 0. 01) . The expression of Caspase 9 in gastric carcinoma was positively correlated with degree of tumor differentiation, TNM staging and lymph node metastasis (P < 0. 01) ,but not with other clinicopathologic factors (P > 0. 05) . The expression of Apollon was negatively correlated to Caspase 9 in gastric carcinoma with statistical significance (r = - 0. 541 1,P < 0. 01) . Conclusions The interaction of Apollon and Caspase 9 may be involved in the gastric carcinogenesis and progression. Apollon is closely related with invasion and metastasis of gastric carcinoma,and it may be a potential treatment target.关键词
