The Role of miR-107 as a Potential Biomarker and Cellular Factor for Acute Aortic Dissection.

Acute aortic dissection (AD) is one of the most severe and highly mortality vascular disease. Its actual prevalence may be seriously underestimated. We studied different expression genes to understand gene profile change between acute AD and nondiseased individuals, and then discover potential biomarkers and therapeutic targets of acute AD. In our study, acute AD differentially expressed mRNAs and miRNAs were identified through bioinformatics analysis on Gene Expression Omnibus data sets GSE52093, GSE98770, and GSE92427. Then, comprehensive target prediction and network analysis methods were used to evaluate protein-protein interaction networks and to identify Gene Ontology terms for differentially expressed mRNAs. Differentially expressed mRNAs-miRNAs involved in acute AD were assessed as well. Finally, the quantitative real-time PCR and experiment was used to validate the results. We found Integral Membrane Protein 2C () was low expressed and miR-107-5p was highly expressed in acute AD tissues. Meanwhile, overexpression miR-107-5p promoted the cell proliferation and inhibited the cell apoptosis in RASMC cells. miR-107-5p inhibited the progression of acute AD through targeted .
