The Cohen Laboratory
Our laboratory is involved in translational research and combines interests from the Department of Surgery, the Department of Pharmacology, Toxicology and Therapeutics, and the Department of Biochemistry at the Medical Center, as well as the Departments of Medicinal Chemistry and Pharmaceutical Chemistry on the Lawrence Campus. Our research focuses on targeted cancer drug development and drug delivery systems in thyroid cancer, melanoma, breast cancer and colon cancer. Current projects include:
- Identifying tumorigenic proteins in thyroid cancer by comparative proteomics for novel drug development using high throughput screening libraries. Novel compounds will then be tested in vitro in thyroid cancer cell-lines as well as in animal in-vivo models for preclinical proof of concept and future human trials.
- Evaluation of HSP90 inhibitor analogs in thyroid cancer cell culture models in vitro and in a nude-mouse in vivo model for preclinical proof of concept. HSP90 is a chaperone protein involved in folding of several proteins involved in tumorigenesis. Several small molecule inhibitors of this chaperone protein are currently being evaluated in phase I and phase II clinical trials. Our lab is investigating new analogues of a HSP90 inhibitor for improved anticancer activity.
- Evaluation of rare medicinal plant extracts in cancer cell lines to determine antiproliferative activity and mechanism of action. Candidate compounds will be evaluated in animal in-vivo models for pre-clinical proof of concept studies and future human trials.
- Development of a working animal model platform for administration of new drug compounds for intraperitoneal chemotherapy in a carcinomatosis model of colorectal cancer and pseudomyxoma peritoneii.
- Development and optimization of an intralymphatic chemotherapy drug delivery platform for treatment of lymphatically spread cancers including colon, breast, melanoma, and lung cancers. This work will be performed in conjunction with the laboratory of Dr. Marcus Forrest, Assistant Professor of Pharmaceutical Chemistry at the University of Kansas, Lawrence Campus.
