Our research program involves the application of drug carriers for the treatment of infectious diseases and cancer. Recent past efforts have been directed toward improving the therapy of brain tumors (as well as others) by targeting tumor blood vessels. Currently we are investigating strategies in increase the perfusion and drug permeability of pancreatic cancers by compromising the ability of cells within the tumor stroma, or extracellular matrix, to maintain the very low tumor blood supply and impermeability to drugs and nanoparticles We employ a variety of experimental approaches, including high-resolution magnetic resonance imaging, liquid chromatography/mass spectrometry, confocal fluorescence microscopy and image analysis, pharmacokinetic/dynamic analysis, and molecular techniques such as quantitative RT-PCR and proteomics. With these techniques, we examine the effects of treatment upon tumor vascular permeability and drug deposition, the localization of the carrier-delivered drug within the tumor, and the molecular mechanisms involved when tumor blood vessels or tumor stroma are attacked during therapy.
Additional interests of the lab that are being pursued actively include understanding the mechanisms of anti-cancer drug action and how they may be modified by changing exposure profile (time vs. concentration). Both genomic and proteomic analysis approaches are utilized in this work, but an approach of increasing importance to our research is the implementation of comprehensive proteomic investigations in order to understand in detail how tumors respond to standard-of-care drugs and new molecularly-targeted drugs.

: Development of liposome-based therapy for ovarian cancer using in vitro and in vivo systems. Project involved developing and evaluating efficacy of ligand-directed liposomes against human ovarian carcinoma in vitro or in vivo in athymic nude mouse model.
: Intracellular traffic of membranes and membrane proteins, using molecular cloning techniques. Project involved use of recombinant DNA techniques to create chimeric proteins containing specific domains of HMG-CoA reductase and reporter genes to allow intracellular localization in living cells. Goal was to understand how membrane-spanning domains of the reductase protein affect intracellular localization. Genes for recombinant proteins were introduced into cultures cells by needle microinjection.
