Angiogenesis is the pathological process of forming new blood vessels from pre-existing vessels. It is one of the main features of many conditions such as cancer and inflammatory diseases. MicroRNAs (miRNAs) are small non-coding RNAs that regulate post-transcriptional gene expression. Recent studies have suggested that miRNAs play a significant role in angiogenesis. The study from Wang et al reported a novel angiomiR, miRNA-329, and its negative correlation with CD 146 expression in angiogenesis. These in vitro and in vivo studies introduce an appealing new way of treating angiogenesis by targeting CD146.
