  • Andrew Lane Lab

    The Lane laboratory is focused on understanding molecular mechanisms underlying chronic rhinosinusitis and particularly the pathogenesis of nasal polyps.  Diverse techniques in molecular biology, immunology, physiology, and engineering are utilized to study epithelial cell innate immunity, olfactory loss, the sinus microbiome, and drug delivery to the nose and sinus cavities. Ongoing work explores how epithelial cells participate in the immune response and contribute to chronic sinonasal inflammation. The lab creates and employs transgenic mouse models of chronic sinusitis to support research in this area. Collaborations are in place with the School of Public Health to explore mechanisms of anti-viral immunity in influenza and rhinovirus, and with the University of Maryland to characterize the bacterial microbiome of the nose and sinuses in health and disease.

  • Becker Lab

    The main focus of the Becker lab has been on the mechanisms and consequences of post-ischemic myocardial inflammation.

    Genomic control of platelet function:

    Aggregation of blood platelets initiates clotting in coronary arteries, the main cause of heart attacks. Our laboratory conducts experiments to understand how genes control platelet function. Through funding by the National Heart Lung and Blood Institute, we have performed candidate gene analysis, linkage studies, whole genome association studies, and now whole genome sequencing in about 2000 healthy subjects from families with early onset coronary artery disease. The subjects are siblings or offspring of an individual identified with coronary artery disease before age 60 in the GeneSTAR Research Program (Genetic Studies of Atherosclerosis Risk). We have identified a large number of common and rare genetic variants associated with platelet aggregation, and although some variants are located in genes known to be important in... the biology of platelet function, most are in non-protein coding regions of genes (introns) or in intergenic regions of the genome. To understand better how these variants influence platelet function, we created pluripotent stem cells from blood mononuclear cells in 257 genotyped GeneSTAR subjects and then transformed the stem cells to megakaryocytes, the source of platelets in the bone marrow. We have determined the entire transcriptome of these megakaryocytes to measure gene expression levels in an effort to functionally link genetic variation with platelet function. We are also interested in epigenetic effects which regulate the amount of gene transcription and resulting protein formation. We have done similar transcriptomic and proteomic studies in blood platelets as we have in stem cell-derived megakaryocytes.

    Our goal is to identify new therapeutic targets for drug development to control excessive platelet aggregation and reduce the risk of heart attack in susceptible individuals. We also hope to use the genetic information to predict who is at greatest risk for platelet aggregation or bleeding, and tailor treatment to effectively apply individualized precision medicine.

    The Becker laboratory also extends its cardiovascular work well beyond platelet function, as noted on the GeneSTAR Research Program website.

  • Chirag Parikh Lab

    Dr. Parikh's research focuses on the translation and validation of novel biomarkers for the diagnosis and prognosis of acute kidney injury. Progress in kidney diseases has been hamstrung by significant heterogeneity within the current disease definitions, which are largely based on serum creatinine. Dr. Parikh's research has addressed this critical challenge by developing biomarkers of renal tubular injury, repair, and inflammation to dissect this heterogeneity. He has assembled multicenter longitudinal prospective cohorts for translational research studies across several clinical settings of acute kidney injury and chronic kidney disease for the efficient translation of novel biomarkers.

    His research is dedicated to the process of applying discoveries generated in the laboratory and in preclinical experiments, the development of clinical studies, and the design of clinical trials. Dr. Parikh's studies have refined the clinical definition in perioperative acute kidney injury and hep...atorenal syndrome, developed strategies to reduce kidney discard in deceased donor transplantation, and advanced regulatory approvals of kidney injury biomarkers. He has also developed biomarkers to identify rapid progressors of early diabetic kidney disease before derangements in serum creatinine. Dr. Parikh's research goal is to translate our understanding of pathophysiological mechanisms into clinical practice and improve the outcomes in patients with kidney disease.

    Dr. Parikh has also been the recipient of numerous honors, including the 2017 Young Investigator Award from the American Society of Nephrology.

  • John Schroeder Lab

    The John Schroeder Lab focuses on understanding the role human basophils and mast cells play in allergic reactions, as it relates not only to their secretion of potent inflammatory mediators (e.g., histamine and leukotriene C4) but also to their production of pro-inflammatory cytokines. We have long utilized human cells rather than cell lines in order to address the parameters, signal transduction and pharmacological aspects underlying clinically relevant basophil and mast cell responses. As a result, the lab has established protocols for rapidly isolating large numbers of basophils at high purity from human blood and for growing culture-derived mast cells/basophils from human progenitor cells. A variety of assays and techniques are also in place for concurrently detecting cytokines and mediators following a wide range of stimuli. These have facilitated the in vitro testing of numerous anti-allergic drugs for inhibitory activity on basophil and mast cell activation. The lab also studie...s counter-regulation between the IgE and innate immune receptors on human immature dendritic cell subtypes. view more

  • The Hackam Lab for Pediatric Surgical, Translational and Regenerative Medicine

    David Hackam’s laboratory focuses on necrotizing enterocolitis (NEC), a devastating disease of premature infants and the leading cause of death and disability from gastrointestinal disease in newborns.

    The disease strikes acutely and without warning, causing sudden death of the small and large intestines. In severe cases, tiny patients with the disease are either dying or dead from overwhelming sepsis within 24 hours. Surgical treatment to remove most of the affected gut results in lifelong short gut (short bowel) syndrome.

    The Hackam Lab has identified a critical role for the innate immune receptor toll-like receptor 4 (TLR4) in the pathogenesis of necrotizing enterocolitis. The lab has shown that TLR4 regulates the development of the disease by tipping the balance between injury and repair in the stressed intestine of the premature infant. Developing an Artificial Intestine A key goal is to create, in the laboratory, new intestines made from patients’ own cells, which can then ...be implanted into the patient to restore normal digestive function. This innovative design could transform child development and quality of life in necrotizing enterocolitis survivors without the risks of conventional donor transplant. view more

  • The Ramanathan Lab

    Chronic rhinosinusitis (CRS) is a leading cause of morbidity globally and is the single most common self-reported chronic health condition and accounts for billions of dollars in health care costs and lost work days annually. Exposure to air pollutants is thought to be a critical modifier of CRS susceptibility. Despite marked reductions in air pollution levels in the United States, the fine particulate component of air pollution (PM2.5) and ultrafine pollutants secondary to traffic continue to remain a recalcitrant issue globally and in the United States. The Ramanathan Lab focuses on studying the role of air pollution (PM2.5) in CRS. In collaboration with scientists at the Bloomberg School of Public Health, we have utilized a state of the art air pollution exposure system to develop a novel mouse model of air pollution induced rhinosinusitis that mimics many of the features of CRS in humans. Our lab uses transgenic mouse models and novel immunologic/genomic techniques to study the mec...hanisms by which PM2.5 causes eosinophilic inflammation and sinonasal epithelial barrier dysfunction. We are also interested in the role of the antioxidant transcription factor, Nrf2, which has shown to stabilize the epithelial barrier and reduce eosinophilia in PM induced rhinosinusitis as a potential therapeutic target. view less

  • William G. Nelson Laboratory

    Normal and neoplastic cells respond to genome integrity threats in a variety of different ways. Furthermore, the nature of these responses are critical both for cancer pathogenesis and for cancer treatment. DNA damaging agents activate several signal transduction pathways in damaged cells which trigger cell fate decisions such as proliferation, genomic repair, differentiation, and cell death. For normal cells, failure of a DNA damaging agent (i.e., a carcinogen) to activate processes culminating in DNA repair or in cell death might promote neoplastic transformation. For cancer cells, failure of a DNA damaging agent (i.e., an antineoplastic drug) to promote differentiation or cell death might undermine cancer treatment.

    Our laboratory has discovered the most common known somatic genome alteration in human prostatic carcinoma cells. The DNA lesion, hypermethylation of deoxycytidine nucleotides in the promoter of a carcinogen-defense enzyme gene, appears to result in inactivation of th...e gene and a resultant increased vulnerability of prostatic cells to carcinogens.
    Studies underway in the laboratory have been directed at characterizing the genomic abnormality further, and at developing methods to restore expression of epigenetically silenced genes and/or to augment expression of other carcinogen-defense enzymes in prostate cells as prostate cancer prevention strategies.

    Another major interest pursued in the laboratory is the role of chronic or recurrent inflammation as a cause of prostate cancer. Genetic studies of familial prostate cancer have identified defects in genes regulating host inflammatory responses to infections.
    A newly described prostate lesion, proliferative inflammatory atrophy (PIA), appears to be an early prostate cancer precursor. Current experimental approaches feature induction of chronic prostate inflammation in laboratory mice and rats, and monitoring the consequences on the development of PIA and prostate cancer.
