The establishment and maintenance of the cardiovascular system such as blood, vessel and heart is an indispensable process throughout embryogenesis and adult life. Successful embryogenesis and injury-mediated tissue/organ repair and regeneration are critically dependent upon angiogenesis or neovascularization. The long-term goal of my group is to understand the detailed mechanisms of cardiovascular development and postnatal vascular regeneration with a special emphasis on transcriptional regulation. In this regard, we previously demonstrated that unlike other ETS factors exhibiting varying degree of redundancy, Etv2 deficient mice die early in gestation due to complete block in blood and blood vessel formation. Further, our studies have revealed that ETV2 acts as a direct upstream inducer of genes critical for generation and function of endothelial cells (ECs). In a subsequent report, we have successfully shown that the dormant ETV2 in adult ECs is reactivated to trigger the angiogenic program in response to ischemic injury. We have also reported that ETV2 alone can directly reprogram terminally differentiated somatic cells into functional ECs, inarguably supporting the idea that ETV2 is a highly specific and potent vasculo-angiogenic factor. We are currently deciphering molecular mechanisms behind ETV2-mediated vascularization by employing basic molecular biology, epigenetics and genetically modified mice coupled with several angiogenesis mouse models.
