  • Florin Selaru Lab

    Principal Investigator:
    Florin Selaru, M.D.
    Medicine

    Research interests in the Florin Selaru Lab comprise the molecular changes associated with the transition from inflammatory states in the GI tract (colon, stomach, biliary tree) to frank cancers. In addition, our current research—funded by the AGA, FAMRI and the Broad Foundation—works to further the understanding of cancer development and progression in the gastrointestinal tract.

  • Follow the Leader: Specialized Cancer Cells Lead Collective Invasion (Ewald Lab)

    Lab Website
    Principal Investigator:
    Andrew Ewald, Ph.D.
    Cell Biology

    Research in the Ewald laboratory starts from a simple question: Which cells in a breast tumor are the most dangerous to the patient and most responsible for metastatic disease? To answer this question, we developed novel 3-D culture assays to allow real-time analysis of invasion. Our data reveal that K14+ cancer cells play a central role in metastatic disease and suggest that the development of clinical strategies targeting these cells will provide novel breast cancer treatments.

  • Frailty Science and the Biology of Healthy Aging

    Lab Website
    Principal Investigator:
    Jeremy Walston, M.D.
    Medicine

    Our Mission: To provide scientists, students, and community members with state-of-the-art information on frailty-related science and how it might impact health and wellness for older adults.

    Our Goal: To improve the understanding of how frailty develops, how to best assess it, and how to best treat and prevent frailty-related decline.

    Research Areas: geriatrics, frailty
  • Frederick Anokye-Danso Lab

    The Frederick Anokye-Danso Lab investigates the biological pathways at work in the separation of human pluripotent stem cells into adipocytes and pancreatic beta cells. We focus in particular on determinant factors of obesity and metabolic dysfunction, such as the P72R polymorphism of p53. We also conduct research on the reprogramming of somatic cells into pluripotent stem cells using miRNAs.

    Research Areas: stem cells, obesity, metabolism, biology
  • Frueh Laboratory

    Lab Website
    Principal Investigator:
    Dominique Frueh, Ph.D.
    Biophysics and Biophysical Chemistry

    The Frueh Laboratory uses nuclear magnetic resonance (NMR) to study how protein dynamics can be modulated and how active enzymatic systems can be conformed. Non-ribosomal peptide synthetases (NRPS) are large enzymatic systems that biosynthesize secondary metabolites, many of which are used by pharmaceutical scientists to produce drugs such as antibiotics or anticancer agents. Dr. Frueh's laboratory uses NMR to study inter- and intra-domain modifications that occur during the catalytic steps of NRPS. Dr. Frueh and his team are constantly developing new NMR techniques to study these complicated enzymatic systems.

    Research Areas: enzymes, proteomics, imaging, drugs, antibiotics, nuclear magnetic resonance, molecular biology
  • Fu Lab

    Lab Website
    Principal Investigator:
    Dax Fu, Ph.D.
    Physiology

    The Fu Lab is a basic research lab that studies zinc transport, with a particular focus on which step in the zinc transport process may be modulated and how. Dr. Fu's lab uses parallel cell biology and proteomic approaches to understand how these physiochemical principles are applied to mammalian zinc transporters and integrated to the physiology of pancreatic beta cells. This research has implications for understanding how zinc transport is related to diabetes and insulin intake.

    Research Areas: cell biology, proteomics, zinc, pancreatic cells, diabetes
  • Gabelli Lab

    Lab Website
    Principal Investigator:
    Sandra Gabelli, Ph.D.
    Medicine

    The Gabelli lab research is focused on structural, mechanistic and functional aspects of enzyme activation that play a role in the biology of human diseases such as cancer, parasitic infection and cardiovascular disease. Their work seeks to:

    1. Understand how molecular events at the recognition level coordinate and trigger events in the cells
    2. Translate structural and mechanistic information on protein:protein interactions at the cytoplasmic level into preventive and therapeutic treatment for human disease.

    To achieve a comprehensive understanding, they are studying cytoplasmic protein-protein interactions involved in regulation of pathways such as PI3K and Sodium Voltage gated channels. Their research integrates structural biology and chemical biology and it is focused on drug discovery for targeted therapies.

    Research Areas: biochemistry, chemical biology, cell biology, structural biology, proteomics, cancer, diarrhea, diabetes, drugs, cellular signaling, inflammation, pharmacology
  • Goley Lab

    Lab Website
    Principal Investigator:
    Erin Goley, Ph.D.
    Biological Chemistry

    The Goley Lab is broadly interested in understanding cellular organization and dynamic reorganization, with particular focus on the roles of the cytoskeleton in these phenomena. We use cell biological, biochemical, genetic and structural approaches to dissect cytoskeletal processes with the aim of understanding how they work in molecular detail. Currently, we are focused on investigating the mechanisms underlying cytokinesis in bacteria. A deep understanding of cytoskeletal function in bacteria will aid in the identification of targets for novel antibiotic therapies and in efforts in synthetic biology.

    Research Areas: biological chemistry, cell biology, genomics, cytoskeleton
  • Green Group

    Lab Website

    The Green Group is the biomaterials and drug delivery laboratory in the Biomedical Engineering Department at the Johns Hopkins University School of Medicine. Our broad research interests are in cellular engineering and in nanobiotechnology. We are particularly interested in biomaterials, controlled drug delivery, stem cells, gene therapy, and immunobioengineering. We are working on the chemistry/biology/engineering interface to answer fundamental scientific questions and create innovative technologies and therapeutics that can directly benefit human health.

  • Greider Lab

    Lab Website

    The Greider lab uses biochemistry to study telomerase and cellular and organismal consequences of telomere dysfunction. Telomeres protect chromosome ends from being recognized as DNA damage and chromosomal rearrangements. Conventional replication leads to telomere shortening, but telomere length is maintained by the enzyme telomerase. Telomerase is required for cells that undergo many rounds of divisions, especially tumor cells and some stem cells. The lab has generated telomerase null mice that are viable and show progressive telomere shortening for up to six generations. In the later generations, when telomeres are short, cells die via apoptosis or senescence. Crosses of these telomerase null mice to other tumor prone mice show that tumor formation can be greatly reduced by short telomeres. The lab also is using the telomerase null mice to explore the essential role of telomerase stem cell viability. Telomerase mutations cause autosomal dominant dyskeratosis congenita. People with ...this disease die of bone marrow failure, likely due to stem cell loss. The lab has developed a mouse model to study this disease. Future work in the lab will focus on identifying genes that induce DNA damage in response to short telomeres, identifying how telomeres are processed and how telomere elongation is regulated. view more
