GSE93978 The miRNA expression characteristics in alopecia areata

Contributors : Youyu Sheng ; Qinping YangSeries Type : Non-coding RNA profiling by arrayOrganism : Homo sapiensTo explore the regulatory effect between miRNAs and mRNAs and the possibility of miRNAs as specific blood-based biomarkers in the developmental process of severe alopecia areata (AA), human peripheral blood samples from AA patients and healthy donors were obtained for analysis. we identified 36 significantly differentially expressed miRNAs in severe active AA patients. MiRNA target gene prediction and functional annotation analysis showed a significant enrichment in several pathways including the ribosome, cancer, cell cycle, insulin signaling, TGF- β signaling and p53 signaling pathways. Analysis of the three kinds of network showed that miR-185-5p, miR-125b-5p, and miR-186-5p might play important and synergistic roles in the developmental process of AA. According to the receiver operating characteristic curve analysis, several miRNAs were se lected for the quantitative real-time PCR validation and further applied as biomarkers to classify severe active AA patients and healthy individuals. Among the miRNAs, hsa-miR-210 and hsa-miR-1246 had high prediction with high accuracy.
