Bioinformatics analysis of angiogenesis-related miRNAs in endothelial progenitor cell exosomes / 中国医师杂志

ABSTRACT

Objective By taking usage of bioinformatics screening methods,this medical research aimed at exploring how the miRNAs in endothelial progenitor cell exosomes relate to the regulation of angiogenesis.Methods miRNAs in endothelial progenitor cells exosomes and angiogenesis-related miRNA was intersected from the existing database to obtain the candidates of miRNA molecules related to angiogenesis in endothelial progenitor exosomes.Results 160 and 50 miRNAs in endothelial progenitor cell candidates were obtained through experimental data analysis and literature searching respectively.600 candidates of angiogenesis-related miRNAs were obtained through literature searching;the top 20 with the highest frequency were selected out.Finally,9 miRNA candidates (miR-126,miR-21,miR-221,miR-92a,miR-199a,miR-210,miR-214,miR-155,miR-146a) that may be highly expressed in endothelial progenitor exosomes and associated with angiogenesis were obtained for the following research.Conclusions Based on data analysis and literature searching,bioinformatics could screen out the target miRNAs for follow-up studies easily and reliably,it is worthy to be widely applied and popularized.
