Dr Awad’s research focuses on the use of human stem cells for regenerative medicine and disease modeling. Her previous work aimed at optimizing the use of hematopoietic stem cells for treatment of diabetic vascular complications, which uncovered a new mechanism of diabetes-induced stem cell dysfunction through modulation of inflammatory response. During her postdoctoral studies, Dr Awad’s research led to the identification of a cancer stem cell population in Ewing’s sarcomas (EWS), the second most common bone tumors in children and young adults. She also tested the use of novel therapeutic molecules against EWS/FLI1 oncogene to overcome EWS stem cell chemo-resistance.
Currently, Dr Awad’s work in Dr Ricardo Feldman’s laboratory focuses on the use of human induced-pluripotent stem cells (iPSCs) to investigate mechanisms responsible for neurodegeneration in Gaucher disease (GD), the most common lysosomal storage disorder. Her research uncovered a novel mechanism by which GBA1 mutations that cause GD, lead to lysosomal dysfunction, through deregulation of the transcription factor EB (TFEB), the master regulator of lysosomal biogenesis and autophagy. This study points to the important role of TFEB alterations in GBA1- associated neurodegeneration and identifies TFEB as a novel therapeutic target in neuropathic GD. GBA1 mutation is also a major risk factor for Parkinson’s disease (PD); therefore these results can have significant implications on understanding PD pathogenesis. Dr Awad was recently awarded a grant from The Michael J. Fox Foundation for Parkinson’s Disease Research to further investigate the mechanisms of GBA1-mediated TFEB dysfunction in GD iPSC-derived dopaminergic neurons.
