生存素与细胞分裂周期相关蛋白5在胃癌及胃间质瘤中的表达及其临床意义
Expression and clinical significance of survivin and cell division cycle associated protein 5 in gastric cancer and gastric stromal tumor
摘要
Abstract
Objective:To detect the expression of survivin and cell division cycle associated protein 5(CDCA5)in gastric cancer and gastric stromal tumor,and analyze the correlation between them and their value in the evaluation of clinicopathological parameters.Methods:Firstly,the expression and correlation of survivin coding gene,BIRC5(baculoviral IAP repeat containing 5)and CDCA5 in gastric cancer were analyzed by GEPIA database.Immunohistochemistry was used to detect the expression of survivin and CDCA5 in 76 cases of gastric cancer and 63 cases of gastric stromal tumor.Spearman's rank correlation test was used to analyze the correlation between survivin and CDCA5 and clinicopathological features of the patients.Then,PROMO database was used to predict transcription factors that may act on their promoters.Finally,the interaction between survivin and CDCA5 was predicted by HDOCK.Results:GEPIA database analysis showed that the expressions of BIRC5 mRNA and CDCA5 mRNA in gastric cancer tissues were significantly higher than those in normal gastric tissues(P＜0.01),and the expressions of BIRC5 mRNA and CDCA5 mRNA in gastric cancer tissues were positively correlated(r=0.79,P＜0.01).Immunohistochemical results showed that the expression levels of survivin and CDCA5 were significantly higher than those of the corresponding paracancerous/paratumoral tissues(P＜0.001),and the expressions of both were positively correlated in gastric cancer and gastric stromal tumor tissues(rgastriccancer=0.410,rgastricstromaltumor=0.347,both P＜0.05).In gastric cancer,survivin was positively correlated with tumor size,lymphatic vessel invasion and TNM stage(all P＜0.05);CDCA5 expression was negatively correlated with tumor differentiation(P＜0.05)and positively correlated with TNM stage(P＜0.05);and the co-positive expression was closely related to tumor size,tumor differentiation lymphatic vessel invasion and TNM stage(all P＜0.05).In gastric stromal tumors,survivin was positively correlated with mitosis and National Institute of Health(NIH)risk stratifications(P＜0.05);CDCA5 was positively correlated with tumor size and NIH risk stratifications(P＜0.05);and the co-positive expression was positively correlated with tumor size,mitosis and NIH risk stratifications(P＜0.05).In addition,PROMO identified 13 transcription factors that might regulate CDCA5 and BIRC5 promoters simultaneously.And HDOCK predicted that there were multiple pairs of interactions between survivin and CDCA5.Conclusion:Under the co-action of multiple transcription factors,survivin and CDCA5 were up-regulated in gastric cancer and gastric stromal tumour with a positive correlation.Both were related to some clinicopathological parameters of gastric cancer and gastric stromal tumor,and the clinical value of combined detection is greater than that of individual molecular detection.关键词
