Analysis of the expression level and predictive value of CLEC16A|miR-654-5p|RARA regulatory axis in the peripheral blood of patients with ischemic stroke based on biosignature analysis by Jiang-jie Hao, Yuan Liu, Jun-hua Lu, Ying Zhao, Ying Lin, Li-qiu Ma, Ping Xue, Bao-yun Jin, Bei-bei Li, Zheng Zhou, Xin-xin Huang, Ting Liu, Meng-yue Li, Jin-ying Lai, Hong-jun Guan

“…In addition, this study conducted a case–control study in which blood samples were collected from stroke patients and healthy medical examiners to validate the core network of ceRNAs constructed by biosignature analysis by real-time fluorescence quantitative qRT-PCR experiments.ResultsA total of 233 DEcircRNAs, 132 DEmiRNAs and 72 DEmRNAs were screened by bioinformatics analysis. circRNA-mediated ceRNA regulatory network was constructed, including 148 circRNAs, 43 miRNAs and 44 mRNAs. …”
