miRNA-sequencing of human non-calcificated and calcificated aortic valves
Several microRNAs (miRNAs) have been identified to play crucial roles in calcificated aortic valves disease, numerous miRNAs are still waiting to be explored. In this study, we compared the miRNA expression profiles of human non-calcified (n=3) and calcified (n=5) aortic valves, and found that compared with the normal control valves, 152 miRNAs were up-regulated and 186 miRNAs were down-regulated in calcified aortic valves. Among the top hit down-regulated miRNAs, we found that the expression level of miR-139-5p was negatively correlated with the osteogenic genes RUNX2 and BMP3, and was also down-regulated during the osteogenic differentiation of primary human aortic VICs. Overall design: miRNA sequencing of human non-calcified (n=3) and calcified (n=5) aortic valves.
