Endogenous microRNAs in human microvascular endothelial cells regulate mRNAs encoded by hypertension-related genes.

ABSTRACT: The goal of this study was to systematically identify endogenous microRNAs (miRNAs) in endothelial cells that regulate mRNAs encoded by genes relevant to hypertension. Small RNA deep sequencing was performed in cultured human microvascular endothelial cells. Of the 50 most abundant miRNAs identified, 30 had predicted target mRNAs encoded by genes with known involvement in hypertension or blood pressure regulation. The cells were transfected with anti-miR oligonucleotides to inhibit each of the 30 miRNAs and the mRNA abundance of predicted targets was examined. Of 95 miRNA-target pairs examined, the target mRNAs were significantly upregulated in 35 pairs and paradoxically downregulated in 8 pairs. The result indicated significant suppression of the abundance of mRNA encoded by ADM by endoge
