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.

: Utilizes liposomes and other carrier techniques to improve the solubility and delivery of taxol and other poorly-soluble anticancer agents.
: Methods of improving the delivery and efficacy of anticancer drugs such as taxol.
: Research interests center on the use of drug carriers such as liposomes to improve the therapy of diseases that include ovarian cancer and opportunistic infections associated with AIDS.
: 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.
: Kinetics of liposome internalization into acidic and enzyme-bearing compartments following endocytosis, using novel fluorescence techniques that allow continuous observation of endocytosis in living cells. Role of cell surface receptor in determining intracellular fate of ligand-directed lipid vesicles. Intracellular vesicular traffic and sorting of model membranes microinjected into cells.
: Mechanisms of membrane fusion: development of a pure-lipid membrane system for study of pH-dependent fusion. Role of neutral-phospholipid headgroup in determining susceptibility of membranes to undergo pH-dependent fusion. Application of system to delivery of macromolecules to cytoplasm following endocytosis of liposomes into acidic intracellular compartment.
: Aerosol and intravenous administration of pentamidine and pentamidine-containing liposomes for treatment of Pneumocystis carinii. Project supplied some of the data filed in support of successful IND application for clinical trial of aerosolized pentamidine in humans. Clinical trial of this work currently is proceeding.
: Cell biology of liposome internalization and intracellular fate of liposome contents.
: Gene delivery in vitro; effect on viral DNA expression of liposome transfection procedures, liposome composition, cell incubation conditions, and chemical modifiers of cell and organelle function.
: Physical properties of liposomes: encapsulation of biologically active compounds.
: Interaction of Picornaviruses (polio and encephalomyocarditis) with cells in culture; transfection with isolated RNA to study cellular resistance to Picornavirus infection. (Under the direction of Robert L. Taber, Ph.D., Department of Medical Viral Oncology, Roswell Park Memorial Institute, Buffalo, N.Y.).
: Avian limb bud morphogenesis: in vitro assay of limb bud polarizing factor activity. (Masters thesis project carried out under the direction of John M. Cairns, Ph.D., Springville Labs Division, Roswell Park Memorial Institute, Buffalo, N.Y.).
: Extensive 'C', Fortran, Java language programming experience on mainframe and microcomputers.
