Research Areas
Diagnostics
My laboratory has a long-standing interest in identifying and validating urine-based bladder cancer (BCa)-associated diagnostic signatures. We were the first to
- Perform gene expression profiling of shed urothelia cells in the urine
- Conduct global proteomics on the enriched glycoproteome of voided urine
- Integrate our gene expression data from shed urothelia and glycoproteome data from voided urine
- Develop and validate a multiplex assay to detect a unique BCa-associated diagnostic signature in voided urine. This assay is set to be released in early 2020 (Oncuria™).
Promising approaches currently under evaluation include comparing the multiplex assay to voided urinary cytology in large multicenter prospective studies.
Cellular Biology
My laboratory has made significant contributions to understanding the factors that influence the development of radio-resistant prostate cancer tumors. These concepts include the role of Bcl-2, COX2 and Akt, as well as the value of using small molecule inhibitors against these targets to restore radiation sensitization.
Therapeutics
My most recent area of research focus has been exploring the biological significance of angiogenin, plasminogen activator inhibitor-1 and CXCL1 in human tumorigenesis. These studies have been conducted in collaboration with Dr. Steve Goodison. Upon unraveling the biologic significance, we have begun devising methodologies to target these molecules with the aim of introducing novel therapeutics to the clinic. Specifically, my laboratory played a major role in describing the biological effects of Bcl-2 on tumoral angiogenesis. Specifically, we went on to identify that Bcl-2 stimulates the expression of CXCL1 in tumor epithelial and tumor endothelial. Each of these preclinical observations has led to clinical evaluation. We are currently completing preclinical toxicology studies as we prepare to bring a novel therapeutic to the clinic in mid-2022.
