RESUMO
Objective:To investigate the serum expression of long non-coding RNA overlapping transcription content KCNQ1OT1 (KCNQ1) gene in patients with coronary artery disease (CAD) and its clinical significance. Methods:A total of 196 patients treated in our hospital were divided into 2 groups:CAD group and Control group, the patients were without CAD. n=98 in each group. Expression levels of serum KCNQ1OT1 and P53 were measured by quantitative RT-PCR;the relationship between KCNQ1OT1, P53 and clinical features in relevant patients were analyzed. Results:Compared with Control group, CAD group had increased expression of serum KCNQ1OT1 and decreased expression of P53, both P Conclusion:CAD patients had obviously increased serum level of KCNQ1OT1;KCNQ1OT1 was independently related to CAD occurrence.
