    Our broad research goals are to identify and validate novel molecular therapeutic targets in he...matopoietic malignancies. We are interested in the identification and pre-clinical development of novel targeted therapies, and, in particular, the “translational” step of this research by using correlative studies to incorporate these novel therapies into existing treatments. Our research is of particular interest to those who wish to be involved in directly translating the results of laboratory bench work into meaningful benefits for patients.

    Currently, we are actively involved in the pre-clinical and clinical development of small molecule kinase inhibitors targeting the FLT3 signaling pathway in acute myeloid leukemia. We are interested in 3 compounds in particular- AC220, a FLT3/KIT inhibitor; crenolanib,a selective FLT3 inhibitor with activity against resistant point mutations; and PLX3397, another inhibitor of KIT and FLT3. The active projects in the lab include:
    1) Characterization of cytotoxic responses of different hematologic malignancies to FLT3 and KIT kinase inhibition; 2) Examination of the interaction of bone marrow stroma and stroma-derived cytokines on the efficacy of these inhibitors; 3) Examination of the differential effect of FLT3 inhibition versus combined FLT3/KIT inhibition on acute myeloid leukemia and bone marrow progenitor cells; and 4) Correlative laboratory studies using blood and marrow samples from patients treated with FLT3 inhibitors, with the aim of developing predictive models for clinical response.

  • Nicholas Flavahan Lab

    Lab Website

    The Nicholas Flavahan Lab primarily researches the cellular interactions and subcellular signal...ing pathways that control normal vascular function and regulate the initiation of vascular disease. We use biochemical and molecular analyses of cellular mediators and cell signaling mechanisms in cultured vascular cells, while also conducting physiological assessments and fluorescent microscopic imaging of signaling systems in isolated blood vessels. A major component of our research involves aterioles, tiny blood vessles that are responsible for controlling the peripheral resistance of the cardiovascular system, which help determine organ blood flow. view more

  • Obesity Hypertension Clinic: Reversing the Negative Cardiovascular Effects of Weight (ReNEW)

    Pediatrics

    Hypertension in children is a major cause of disease, including early onset heart disease. Up t...o 25% of children who are overweight or obese have hypertension (high blood pressure), and children with obesity are at greater risk for having other cardiovascular disease risk factors such as high cholesterol and diabetes. The ReNEW Clinic at The Johns Hopkins University provides an innovative multidisciplinary approach to the evaluation and treatment of obesity-related hypertension to help prevent and treat cardiovascular disease. This clinic is designed for children with elevated blood pressure (prehypertension and hypertension) and a BMI at or above the 85th percentile. Many children in this clinic are enrolled in a longitudinal registry to help researchers learn how to better care for children with multiple risk factors for heart disease.

    Research in the Paul Rothman Lab has focused on cytokines. We’ve investigated the role these mo...lecules play in the normal development of blood cells as well as the abnormal blood-cell development that leads to leukemia. We’ve also studied the function of cytokines in immune system responses to asthma and allergies. view more

  • Peter Abadir Lab

    Principal Investigator:
    Peter Abadir, M.D.
    Medicine

    Research in the Peter Abadir Lab focuses on the renin-angiotensin system (RAS), a signaling pat...hway that regulates blood pressure and has been linked independently to both aging and inflammation. We’re particularly interested in changes in RAS that occur with aging. We also study signal transduction and the role of the crosstalk between angiotensin II receptor in aging and are interested in understanding the function of angiotensin II in the process of vascular aging. view more

  • Peter Agre Lab

    Principal Investigator:
    Peter Agre, M.D.
    Biological Chemistry

    Work in the Peter Agre Lab focuses on the molecular makeup of human diseases, particularly mala...ria, hemolytic anemias and blood group antigens. In 2003, Dr. Agre earned the Nobel Prize in Chemistry for discovering aquaporin water channels. Building on that discovery, our recent research has included studies on the protective role of the brain water channel AQP4 in murine cerebral malaria, as well as defective urinary-concentrating ability as a result of a complete deficiency in aquaporin-1. We also collaborate on scientific training and research efforts with 20 Baltimore-area labs and in field studies in Zambia and Zimbabwe. view more

  • Pluznick Lab

    Principal Investigator:
    Jennifer Pluznick, Ph.D.
    Physiology

    The Pluznick Lab is interested in the role that chemosensation plays in regulating physiologica...l processes, particularly in the kidney and the cardiovascular system. We have found that sensory receptors (olfactory receptors, taste receptors, and other G-protein coupled receptors) are expressed in the kidney and in blood vessels, and that individual receptors play functional roles in whole-animal physiology. We are currently working to identify the full complement of sensory receptors found in the kidney, and are working to understand the role that each receptor plays in whole-animal physiology by using a variety of in vitro (receptor localization, ligand screening) and in vivo (whole-animal physiology) techniques. view more

  • Richard John Jones Lab

    Principal Investigator:
    Richard Jones, M.D.
    Medicine

    The Richard J. Jones Lab studies normal and cancerous stem cells in order to make clinical impr...ovements in areas such as blood and marrow transplantation (BMT). We discovered one of the most common stem-cell markers, Aldefluor, which identifies cells based on their expression of aldehyde dehydrogenase 1 (ALDH1), and have used this marker to detect and characterize normal stem cells and cancer stem cells from many hematologic malignancies. We also developed post-transplant cyclophosphamide and effective related haploidentical BMT. view more

  • Rita Kalyani Lab

    Principal Investigator:
    Rita Kalyani, M.D., M.H.S.
    Medicine

    Research in the Rita Kalyani Lab examines the decreased physical functioning observed in patien...ts with diabetes as they age. Through several ongoing epidemiological cohorts, we are investigating the association of high blood glucose and high insulin levels with accelerated muscle loss, and possible contributions to the physical disability observed in diabetes. We are currently involved in clinical studies that aim to understand the underlying mechanisms for these associations and to facilitate the development of novel strategies to prevent muscle loss and disability in people with diabetes. view more

  • Samuel R. Denmeade Laboratory

    Lab Website

    The main research goals of my laboratory are: (1) to identify and study the biology of novel ca...ncer selective targets whose enzymatic function can be exploited for therapeutic and diagnostic purposes; (2) to develop methods to target novel agents for activiation by these cancer selective targets while avoiding or minimizing systemic toxicity; (3) to develop novel agents for imaging cancer sites at earliest stages. To accomplish these objectives the lab has originally focused on the development of prodrugs or protoxins that are inactive when given systemically via the blood and only become activated by tumor or tissue specific proteases present within sites of tumor. Using this approach, we are developing therapies targeted for activation by the serine proteases prostate-specific antigen (PSA), human glandular kallikrein 2 (hK2) and fibroblast activation protein (FAP) as well as the membrane carboxypeptidase prostate-specific membrane antigen (PSMA). One such approach developed in the lab consists of a potent bacterial protoxin that we have reengineered to be selectively activated by PSA within the Prostate. This PSA-activated toxin is currently being tested clinically as treatment for men with recurrent prostate cancer following radiation therapy. In a related approach, a novel peptide-cytotoxin prodrug candidate that is activated by PSMA has been identified and is this prodrug candidate is now entering early phase clinical development. In addition, we have also identified a series of potent inhibitors of PSA that are now under study as drug targeting and imaging agents to be used in the treatment and detection of prostate cancer.
