长链非编码RNA在结肠癌组织与癌旁组织中的表达研究
Study on expression of long non-coding RNA in colon cancer tissues and adjacent tissues
摘要
Abstract
AIM:To screen the differentially expressed long non-coding RNA(lncRNA)in colon cancer,and to explore its expression in colon cancer tissues and adjacent tissues.METHODS:The "Colon adenocarcinoma:Person neoplasm cancer status" which consisted of 36 cases of colon cancer tissues and 29 cases of normal colonic tissues was downloaded from the lncRNAtor database.The candidate genes were selected from these differentially expressed lncRNAs based on artificial criterion(P<0.01;fold change ≥2 or<0.5)and then validated by real-time PCR in 60 pairs of colon cancer tissues and adjacent tissues.RESULTS:A total of 50 lncRNAs were differentially expressed in colon cancer tis-sues,including 28 up-regulated and 22 down-regulated(P<0.01).The verifying results displayed that HNF1A-AS1 and ZDHHC8P1 were up-regulated(P<0.01),and SUZ12P expression was down-regulated(P<0.05),but the expression of AC069513.3 was not statistically significant between colon cancer tissues and adjacent tissues.The abilities of HNF1A-AS1,ZDHHC8P1,SUZ12P and AC069513.3 to discriminate the colon cancer from normal adjacent tissue by the ROC curve with an AUC of 0.729(sensitivity 78％,specificity 67％),0.617(sensitivity 68％,specificity 55％),0.689(sensitivity 66％,specificity 55％)and 0.518(sensitivity 52％,specificity 48％)were observed.CONCLUSION:Long non-coding RNA HNF1A-AS1 and ZDHHC8P1 are up-regulated and SUZ12P is down-regulated in colon cancer tis-sues,suggesting that they may be involved in the pathogenesis of colon cancer.关键词
