George T. Cicila, Ph.D.
University of Pennsylvania, 1986
My major interests are the inheritance of complex traits, with a focus on cardiovascular and related phenotypes. These include blood pressure, intrinsic aerobic running capacity, cardiac performance, and obesity. We are also studying a mutation that regulates the length of telomeres.
Jennifer W. Hill, Ph.D.
Northwestern University, 2003
I am interested are in the hypothalamic homeostatic mechanisms controlling body weight and fertility and the interactions between them. My hypothesis is that the suppression of reproductive cyclicity during states of negative energy balance results from the action of circulating metabolic factors (such as leptin, insulin, ghrelin, glucose, LC-FAs or PYY3-36), in the hypothalamus. My experimantal approach includes use of timed, targeted genetic manipulation, such as tissue-specific gene deletion.
Bina Joe, Ph.D.
University of Mysore, Mysore, Karnataka, India, 1996
The focus of the Joe Lab is on the molecular genetics of complex traits. The current thrust area is on studying hypertension through a systems biology approach utilizing custom-genetically altered models of differential blood pressure.
Edith Mensah-Osman, M.D., Ph.D.

Wayne State University, Detroit, USA; Ph.D., 2003
My lab is currently working on three different areas of research. In the first we are investigating the perturbations in the signaling pathways that contribute or are affected by obesity, fatty liver disease and type 2 diabetes. In the second project, I am investigating the role of a nuclear receptor (SXR/PXR) that regulates drug metabolizing and multidrug resistance proteins in the pathophysiology of cancer. Specifically, we are interested in characterizing a variant form of this receptor found in osteosarcoma an aggressive malignancy of the bone to determine its role in tumor progression and drug resistance. In the third project, I am elucidating the role of somatostatin in the development of ileal carcinoid tumors found in the intestinal tract.
Nikolai Modyanov, Ph.D., D.Sc.

Russian Academy of Sciences, D.Sc., 1987
Research in my lab is focused on the molecular aspects of ion transport across biological
membranes. These studies led to the recent discovery of a novel structural member
of the mammalian X,K-ATPase ß-subunit gene family, designated ßm due to its exclusive
expression in skeletal and heart muscles. Studies are underway to elucidate functions
of this hitherto unknown, muscle-specific protein.

Cornell University, 1970
Current research interests are focused on the development of a single-injection, multi-year controlled-release wildlife contraceptive vaccine to alleviate suffering faced by numerous species which are overpopulating fixed-size habitats and on assessment environmental stress due to chronically deteriorating habitats in wildlife and fishes via fecal cortisol measurement.
Guillermo Vazquez, Ph.D.
Universidad Nacional del Sur, Argentina, 1997
The focus of our research is on the role of Canonical Transient Receptor Potential
(TRPC) channels in endothelial dysfunction/inflammation associated to cardiovascular
and metabolic diseases. The repertoire of TRPC isoforms expressed in endothelium from
different vascular beds, signaling modulating channel function, and molecular/cellular
outcomes of TRPC-mediated Ca2+ entry, are some of the subjects of our studies.

Amir Askari, Ph.D.
Cornell University, 1960
Current research is on the interactions of cardiac Na/K-ATPase (the sodium pump) with neighboring proteins of the plasma membrane, leading to the recently appreciated signal transducing functions of this enzyme that regulate the effects of digitalis drugs on cardiac hypertrophy and heart failure.

Signal transduction of Na/K-ATPase in cardiovascular system and cancer cells
Sandrine Pierre, Ph.D.
Aix-Marseille II University, France, 2000
Westudy specific intracellular pathways involved in the integrated response of the myocardium to ischemia-reperfusion injury and metabolic disturbances. Our goal is to therapeutically address cardiomyocyte death following myocardial infarction and cardiovascular complications associated with obesity and insulin-resistance. We address these issues by combining techniques of molecular and cell biology with ex-vivo and in-vivo assessments of cardiac function in genetically altered mice.
Cynthia M. Smas, D.Sc.
Harvard University, 1994
Work in Dr. Smas’ laboratory addresses gene regulation and cell differentiation using two model systems: 1.) Differentiation of fibroblastic mesenchymal precursor cells to mature adipocytes that occurs in normal development but which may be accelerated in obesity; and 2.) Neuroendocrine differentiation that occurs during the course of prostate cancer and which may support a transition to androgen-independent tumor growth.
DEPARTMENT OF MEDICAL MICROBIOLOGY AND IMMUNOLOGY
Mark Wooten, Ph.D.
University of Mississippi Medical Center, 1995
Dr. Wooten's laboratory is interested in the host/pathogen interactions that lead to the development of Lyme disease. Borrelia burgdorferi is highly infectious and especially adept at evading host defenses and persisting in various tissues, even in an apparently immunocompetent host. His research takes an immunological approach to identification of host mechanisms involved in control of spirochete persistence and in mediating the inflammatory pathology related to Lyme disease.
DEPARTMENT OF MEDICINE
Khew-Voon Chin, Ph.D.
Rutgers University, 1988
Dr. Chin’s laboratory has three areas of research focus: (i) They are interested in novel cAMP signaling mechanisms involving the regulatory subunit (R) of the cAMP dependent protein kinase (PKA). They have shown that the R subunit can interact with novel protein partners and regulate cell growth. (ii) They apply expression genomics (expression profiling by DNA microarray) for the identification of genes that contribute to drug resistance in cancer treatment. (iii) They are also studying the transcriptional regulation of adipogenesis and the molecular actions of a novel small molecule that disrupts this pathway and thus inhibition of fat cells differentiation.

Cardiotonic steroids-induced regulation of sodium reabsorption in renal proximal tubule. Ouabain inhibits sodium reabsorption in proximal tubule, a process mediated by ouabain-activated Na/K-ATPase signaling. This regulation includes ouabain-induced trafficking of the Na/K-ATPase and NHE3 (sodium-proton exchanger isoform 3), as well as transcriptional regulation of NHE3.

Cellular and molecular basis of peptide and protein secretion of peptide neurotransmitters and hormones; Ca2+ signaling mechanisms; Neuroendocrine cancer; Mitochondrial function in health and disease. Studies employ a combination of electrophysiological and optical methods to follow in real-time the secretory activity and Ca2+ dynamics of single isolated nerve endings and a variety of acutely isolated or cultured cell types.

Previously, we have demonstrated that a class of anti-diabetic drugs TZD have adverse effects on bone by causing bone loss and affecting fracture healing in animal models. We have also showed that this process can be prevented by using slightly modified TZD drugs, which retain their beneficial anti-diabetic effects but are lacking adverse effects on bone. Currently, we are investigating molecular mechanisms by which TZDs induce bone loss and investigating the means by which diabetic bone status can be improved by using bone-specific gene and stem cell therapies, as well as pharmacological therapies.
DEPARTMENT OF SURGERY
David C. Allison, M.D., Ph.D.
University of Michigan College of Medicine, M.D.
University of Chicago, Ph.D.
Dr. Allison’s laboratory is studying the mechanisms responsible for the selection of chromosomal abnormalities in aneuploid cancers. We are specifically testing the possibility that chromosomal abnormalities are conserved to retain cell-survival genes required for tumor-cell growth coincident with the loss of chromosomal regions containing tumor suppressor genes retarding tumor growth, or losses of heterozygosity (LOHs). Special attention is being paid to the possibility that tumor LOHs might prove to be an important indicator for breast cancer patients. Techniques employed in the laboratory include Gene Mapping and Expression Arrays, Spectral Karyotyping analysis of cancer chromosomes, and Laser Capture Microdissection of breast cancer cells in paraffin-embedded tissue blocks.
