Dr. Jiri Adamic

Department of Interdisciplinary Oncology, LSUHSC

Cancer Proteomics and Metabolomics.

Research Interest: Dr. Jiri Adamic’s research focuses on taking integrated proteomics, metabolomics, and analytical approaches to identify molecular mechanisms of disease, its biomarkers and develop technologies for their detection and accurate quantification. Particularly interest is in irreversible modifications of proteins and metabolites and their potential interference with cellular processes. These activities include both development of new analytical methods and their application on the specific aging related disease such as cancer, neurodegeneration, and autoimmune disorders. In translational research, we have recently introduced a plasma separation device used to volumetrically collect a plasma aliquot independent of whole blood application volume. This process requires no power and circumvents requirements for venipuncture-phlebotomy training, needles, special vials and equipment, refrigeration, and centrifugation normally associated with traditional plasma methods. The air-dried plasma aliquot can be inexpensively transported with minimal biohazard to a centralized laboratory for quantitation of biomarkers for disease or physiological function.

Department of Pathology and Laboratory Medicine, Tulane University

Molecular pathogenesis of liver cancers.

Research Interests: Dr. Huang’s lab has been working on deciphering the molecular pathogenesis of liver malignancy with specific focuses on alpha-ketoglutarate dependent enzymes, including aspartatebeta-hydroxylase (ASPH), which functions in catalyzing hydroxylation of aspartate and asparagine residue of EGF like domain, and Tet methylcytosine dioxygenase 1 (TET1) which catalyzes the formation of 5-hydroxymethylcytosine leading to DNA demethylation. He has identified that ASPH is highly expressed in cholangiocarcinoma (CCA) but barely detectable in bile ducts. His recent research findings further reveal that several potential compounds which targetASPH enzymatic activity could robustly suppress CCA progression. He and his team members are working on further characterizing the therapeutic potential of these compounds in multiple preclinical CCA models. His lab is also involved in the TET1-mediated epigenetic modification in alcoholic liver disease (ALD)associated hepatocellular carcinoma (HCC) progression.

Dr. Anup Kundu

Biology Department, Xavier University

Cancer Drug Delivery Development Using Nanoparticles and Emulsions, and Screening and Testing.

Research Interest: Dr. Anup Kunda’s research is in highly interdisciplinary areas of nanoparticle formulation, characterization and targeted delivery of drugs and genes into breast cancer cells. The development of multi-drug resistance (MDR) in cancer cells is of grave concern, limiting the efficacy of anticancer agents and, hence, the failure of breast cancer therapy.Clinical research and application revealed that in spite of it’s potential anticancer effects, doxorubicin is highly toxic, and its long-term application may cause dose-dependent irreversible cardiomyopathy, severe cardiac toxicity, or liver damage, thereby limiting its application in breast cancer treatment.As such, the greater potential of using doxorubicin as anticancer therapeutic depends on the availability of a targeted delivery vehicle, which will not only enhance the killing of cancer cells but also minimize the off-target toxicity to non-cancerous cells. The goal of Kundu lab at Xavier University of Louisiana is to enhance the delivery of doxorubicin by formulating an aptamer-labeled liposomal nanoparticle delivery system that will carry and deliver doxorubicin specifically into chemo resistant breast cancer cells.

Dr. Giblert Morris

Department of Medicine, Tulane University

Role of gherpesviruses in the Pathogenesis of Lung Adenocarcinoma.

Research Interest: Inhalation of established human lung carcinogens, such as cigarette smoke or asbestos, elicits Type 17 inflammation in the lungs of mice.  These carcinogen-associated inflammatory cytokines are also induced by cherpesviruses.  Over expression of eitherType 17 cytokine, IL-17A or IL-22, accelerates growth of murine lung tumors and correlates with a worse prognosis in non-small cell lung cancer in humans.  Our goal is to use our experience from murine lung tumor models to better understand the health effects of Oherpesviruses.  A theme of these experiments is that eherpesviruses alter lung inflammation, which drives lung tumorigenesis and augments the tumor-promoting immune response to other environmental exposures.  A better understanding of these immune alterations provided by developing a murine model will improve our attempts to determine the lung cancer risks of nherpesvirus and its interaction with environmental exposures.

 

Dr. Francesca Peruzzi

Department of Medicine, LSUHSC

Epigenetic and Metabolic Reprogramming of Monocytes inChronic HIV Infection.

Research Interest: People living with HIV (PLWH) are a thigh risk of developing secondary illnesses including cancer. Although combined antiretroviral therapy (cART) reduces the viral load and increases the lifespan of these patients, it does not fully restore the full function of immune cells, sensitizing them to secondary infections and other pathologies.  Recent studies indicate the presence of specific epigenetic and metabolic changes in monocytes of PLWH that are associated with dysfunctional immune responses observed in these cells. While analyses of epigenetic changes of innate immune cells of HIV+ individuals could reveal novel mechanisms underlying cancer development and/or progression, this area of research requires further investigation.  Dr. Peruzzi’s experimental research model involves isolation of CD14+ monocytes from HIV+ patients and healthy age-matched controls and the in vitro analysis of these cells following their polarization toward a pro-inflammatory (M1-like) macrophage phenotype. When exposed to environmental signals, such as β-glucan or lipopolysaccharide (LPS)endotoxins, normal monocytes will execute two types of innate programming called “trained immunity” and “tolerance” characterized by either hyper-responsiveness or hypo-responsiveness to secondary stimuli, respectively. Our data show that this delicate balance between trained immunity and tolerance is defective in monocytes of PLWH. Our current project investigates the molecular mechanisms linking epigenetic modifications and metabolic reprogramming to a dysfunctional immune response in HIV+ individuals with low or undetectable viral load.
