Sean Taverna LaboratoryPrincipal Investigator:
Sean Taverna, Ph.D.
Pharmacology and Molecular Sciences
The Taverna Laboratory studies histone marks, such as lysine methylation and acetylation, and h...ow they contribute to an epigenetic/histone code that dictates chromatin-templated functions like transcriptional activation and gene silencing. Our lab uses biochemistry and cell biology in a variety of model organisms to explore connections between gene regulation and proteins that write and read histone marks, many of which have clear links to human diseases like leukemia and other cancers. We also investigate links between small RNAs and histone marks involved in gene silencing. view moreResearch Areas: biochemistry, histone marks, cell biology, leukemia, cancer, epigenetics, eukaryotic cells, gene silencing, RNA
Shanthini Sockanathan LaboratoryLab WebsitePrincipal Investigator:
Shanthini Sockanathan, D.Phil.
The Shanthini Sockanathan Laboratory uses the developing spinal cord as our major paradigm to d...efine the mechanisms that maintain an undifferentiated progenitor state and the molecular pathways that trigger their differentiation into neurons and glia. The major focus of the lab is the study of a new family of six-transmembrane proteins (6-TM GDEs) that play key roles in regulating neuronal and glial differentiation in the spinal cord. We recently discovered that the 6-TM GDEs release GPI-anchored proteins from the cell surface through cleavage of the GPI-anchor. This discovery identifies 6-TM GDEs as the first vertebrate membrane bound GPI-cleaving enzymes that work at the cell surface to regulate GPI-anchored protein function. Current work in the lab involves defining how the 6-TM GDEs regulate cellular signaling events that control neuronal and glial differentiation and function, with a major focus on how GDE dysfunction relates to the onset and progression of disease. To solve these questions, we use an integrated approach that includes in vivo models, imaging, molecular biology, biochemistry, developmental biology, genetics and behavior. view moreResearch Areas: glia, biochemistry, neurons, imaging, developmental biology, genomics, spinal cord, behavior, molecular biology

Stivers LabLab WebsitePrincipal Investigator:
James Stivers, Ph.D.
Pharmacology and Molecular Sciences
The Stivers Lab is broadly interested in the biology of the RNA base uracil when it is present ...in DNA. Our work involves structural and biophysical studies of uracil recognition by DNA repair enzymes, the central role of uracil in adapative and innate immunity, and the function of uracil in antifolate and fluoropyrimidine chemotherapy. We use a wide breadth of structural, chemical, genetic and biophysical approaches that provide a fundamental understanding of molecular function. Our long-range goal is to use this understanding to design novel small molecules that alter biological pathways within a cellular environment. One approach we are developing is the high-throughput synthesis and screening of small molecule libraries directed at important targets in cancer and HIV-1 pathogenesis. view moreResearch Areas: biophysics, enzymes, cell biology, uracil, cancer, HIV, DNA, RNA
Stuart C. Ray LabLab WebsitePrincipal Investigator:
Stuart Ray, M.D.
Chronic viral hepatitis (due to HBV and HCV) is a major cause of liver disease worldwide, and a...n increasing cause of death in persons living with HIV/AIDS. Our laboratory studies are aimed at better defining the host-pathogen interactions in these infections, with particular focus on humoral and cellular immune responses, viral evasion, inflammation, fibrosis progression, and drug resistance. We are engaged in synthetic biology approaches to rational vaccine development and understanding the limits on the extraordinary genetic variability of HCV. view moreResearch Areas: immunology, Hepatitis, AIDS, HIV, hepatitis B, hepatitis C, liver diseases, synthetic biology
Susan Michaelis LabPrincipal Investigator:
Susan Michaelis, Ph.D.
The Michaelis Laboratory's research goal is to dissect fundamental cellular processes relevant ...to human health and disease, using yeast and mammalian cell biology, biochemistry and high-throughput genomic approaches. Our team studies the cell biology of lamin A and its role in the premature aging disease Hutchinson-Gilford progeria syndrome (HGPS). Other research focuses on the core cellular machinery involved in recognition of misfolded proteins. Understanding cellular protein quality control machinery will ultimately help researchers devise treatments for protein misfolding diseases in which degradation is too efficient or not enough. view moreResearch Areas: biochemistry, cell biology, protein folding, lamin A, aging, genomics, Hutchinson-Gilford progeria syndrome, yeast
Systems Biology LaboratoryPrincipal Investigator:
Aleksander Popel, Ph.D.
The Systems Biology Lab applies methods of multiscale modeling to problems of cancer and cardio...vascular disease, and examines the systems biology of angiogenesis, breast cancer and peripheral artery disease (PAD).Research Areas: peripheral artery disease, breast cancer, systems biology, computational biology, cancer, cardiovascular, age-related macular degeneration, bioinformatics, angiogenesis, microcirculation
Using coordinated computational and experimental approaches, the lab studies the mechanisms of breast cancer tumor growth and metastasis to find ways to inhibit those processes.
We use bioinformatics to discover novel agents that affect angiogenesis and perform in vitro and in vivo experiments to test these predictions. In addition we study protein networks that determine processes of angiogenesis, arteriogenesis and inflammation in PAD. The lab also investigates drug repurposing for potential applications as stimulators of therapeutic angiogenesis, examines signal transduction pathways and builds 3D models of angiogenesis.
The lab has discovered over a hundred novel anti-angiogenic peptides, and has undertaken in vitro and in vivo studies testing their activity under different conditions. We have investigated structure-activity relationship (SAR) doing point mutations and amino acid substitutions and constructed biomimetic peptides derived from their endogenous progenitors. They have demonstrated the efficacy of selected peptides in mouse models of breast, lung and brain cancers, and in age-related macular degeneration.

Venu Raman Research LabPrincipal Investigator:
Venu Raman, Ph.D.
Radiology and Radiological Science
The Raman laboratory is within the Division of Cancer Imaging Research in the Department of Rad...iology and Radiological Science. The focus of the laboratory is bench-to-bed side cancer research. We integrate molecular and cellular biology, developmental biology, cancer biology, molecular imaging techniques to study cancer formation and progression. Many of the projects in the lab investigate dysregulated genes in cancer and the translatability of this information to a clinical setting. One such project is to functionally decipher the role of a RNA helicase gene, DDX3, in the biogenesis of multiple cancer types such as breast, lung, brain, sarcoma, colorectal and prostate. Additionally, using a rational drug design approach, a small molecule inhibitor of DDX3 (RK-33) was synthesized and its potential for clinical translation is being investigated. view moreResearch Areas: breast cancer, cancer, in vitro findings, molecule inhibitors
