The focus of Dobrian lab research is on mechanisms of adipose tissue remodeling and co-morbidities of obesity.
Project 1: Vascular remodeling in obesity and role of endothelial extracellular vesicles. Adipose tissue plasticity requires cellular adaptation of multiple cell types to accommodate long term caloric intake fluctuations. Endothelial cell is one of the key cells that support such plasticity. A number of maladaptive changes in the endothelium may have paracrine and endocrine effects on other vascular beds. Our work is focused on understanding the role of extracellular vesicles produced by dysfunctional endothelium in obese adipose tissue on phenotype and function of endothelial cells from distant vascular beds; including coronary endothelium and tumor vasculature. The mechanisms underlying these effects include transfer of metabolic and angiostatic signatures via vesicular miRNA transcriptome and proteome.
Project 2 : Adipogenic potential of human adipose tissue endothelial cells. We showed that a subset of human adipose tissue endothelial progenitors can trans-differentiate into functional white and beige adipocytes. We are currently investigating the pathways responsible for the robustness of adipogenic potential. Amongst those, the insulin signaling and TGFβ signaling are a primary focus and miRNAs that can potentially target key signaling molecules in such pathways are currently under investigation.
Project 3: Mechanisms that exacerbate liver disease and type2 diabetes due to sleep fragmentation. This is a collaborative project with Dr. Larry Sanford's lab in the Department of Pathology and Anatomy at EVMS. Using different mouse models of liver disease and type2 diabetes we currently investigate the role of miRNAs in extracellular vesicles on pro-fibrotic and inflammatory pathways in liver and pancreata.
