OverviewAI-generated summary
Ravi W. Sun's research focuses on the cellular and molecular mechanisms underlying vascular malformations. His work investigates the hyperproliferative nature of endothelial cells in conditions such as venous malformations and arteriovenous malformations. Sun has published studies examining dysregulated signaling pathways, including TGF-β/BMP, and the role of specific microRNAs, such as microRNA-21, in driving cell proliferation and inhibiting tumor suppressor genes like PDCD4 in lymphatic malformations. His research also explores the involvement of mural cells in endothelial-to-mesenchymal transition within arteriovenous malformations and the potential therapeutic inhibition of factors like Angiopoietin-2 to control malformation cell growth. Sun collaborates with several researchers at the University of Arkansas for Medical Sciences, including Graham M. Strub and Gresham T. Richter, with whom he has co-authored multiple publications.
