Research Abstract

MicroRNAs are a novel layer of gene regulatory mechanism that induce post-transcriptional silencing. In this study, we analyzed the non-cell autonomous regulation of vasculogenesis by a muscle-specific miRNA, miR-1, in zebrafish. Our results indicated that miR-1 modulates vasculogenesis via the negative regulation of secreted factor VEGF.
