Research in Lay Terms
Every cell in human body resides in a certain location, where it has an oxygen supply needed for its proper function. When oxygen conditions change, cellular behavior changes accordingly. In our lab we study these changes in cell behavior at the molecular, cellular, and organism levels. Knowing these outcomes will help us to exploit them for stem cell maintenance, cell differentiation, cancer therapy design, stroke management.

Research Focus
Primary research focus is on the role of hypoxic micro-environment in regulation of cell behavior.

Detail on Research
My primary scientific interests lie in dissecting signaling pathways regulated by hypoxia contributing to theaggressive behavior of ovarian and renal cancer stem cells (mainly metastasis); as well as understanding therole of hypoxia in the maintenance of normal epithelial stem cells. The physiologic range of oxygen for mosttissues is between 4-8% oxygen (normoxia) in contrast to the atmospheric 20% oxygen used for tissueculture experiments. Cellular hypoxia (usually <1-5% oxygen depending on the tissue) is a common stress innormal development and numerous pathological conditions, including cancer and ischemia. An hypoxicmicroenvironment is very powerful at rewiring cellular signaling pathways leading to changes in cellularbehavior ranging from metabolism (favoring glycolysis) to dedifferentiation. In recent years, hypoxicmicroenvironments have been linked to stem cell niches (such as bone marrow Hematopoietic stem cell andEmbryonic stem cell niches), reprogramming of iPS cells, as well as maintenance of Cancer Stem Cells(CSC), making it an important field of study for regenerative medicine.
