Research Interests

My research interest focuses on identifying the cellular and molecular mechanisms in the pathophysiology of cancer and to exploit new pathways towards the goal of developing novel therapies. I have been especially interested in the role of Transforming Growth Factors-β (TGF-β) in murine and human Osteosarcoma (OS) and investigated the use of a TGF-β inhibitor as a new therapeutic approach for treating OS. OS is the most common bone sarcoma in pediatric and adolescent & young adult patients. It has been shown that TGF-b production is increased in the sera of OS patients. I have found that a small molecule inhibitor of TGF-β type 1 Receptor kinase, significantly reduced OS growth through tumor-intrinsic and extrinsic immune-related factors. Notably, I found that c-Myc regulation by TGF-beta is a novel therapeutic target in OS. Concomitantly, I found that TGF-β inhibitor increased immune effectors (e.g., T cells and NK cells) and inhibited immune suppressors (e.g., M2-like TAM, MDSC) in the OS tumor environment.
