Research Summary: 
Tumor-stroma interactions; heparan sulfate proteoglycans in cancer.
Research Detail: 

My research focuses on the role of heparan sulfate proteoglycans (HSPGs) in tumorigenesis and cancer progression. HSPGs are hybrid molecules, which consist of core proteins and heparin-like polysaccharide domains. HSPGs are found in abundance on cell surfaces and in the extracellular matrix. One project focuses on the role of the HSPG syndecan-1 in stromal fibroblasts of breast carcinomas. The goal is to decipher the mechanisms by which stromal syndecan-1 stimulates breast carcinoma growth and invasion. A separate project aims at identifying the mechanisms by which the HSPG glypican-1 regulates cell cycle progression in brain tumor cells.
