Developmental origins of adult obesity

Research Description

Dr. Ross, alongside fellow LA BioMed researcher, Mina Desai, PhD, investigates the mechanisms of developmental origins of obesity using rodent models of maternal under- and over-nutrition as well as exposure to environmental chemical endocrine disruptors (e.g., bispheol A) during pregnancy and/or lactation. They study the offspring using multiple approaches that include stem cells, epigenetics, gene expression, cellular signaling, physiology and transgenic mice. Their two main areas of research include:
1) Role of appetite in programmed obesity – investigating the properties of neural stem cells that populate and develop arcuate nucleus center (appetite regulatory site) and the underlying contributory mechanism.
2) Role of adipogenesis in programmed obesity - investigating the properties of adipocyte stem cells and the mechanisms which predispose to increased fat storage.
