  • Susan Hutfless Lab

    The Susan Hutfless Lab uses administrative data to investigate epidemiologic questions about the causes of and treatments for chronic diseases, with a focus on gastrointestinal disorders. Our team has provided epidemiologic expertise to help design and analyze large-dataset studies of cervical cancer, colorectal cancer and mortality related to inflammatory bowel disease (IBD). We also have conducted research on infection-related triggers of Crohn’s disease in susceptible military personnel as well as prenatal and childhood predictors of pediatric-onset IBD.

  • The Burns Lab

    Our research laboratory studies the roles mobile DNAs play in human disease. Our group was one of the first to develop a targeted method for amplifying mobile DNA insertion sites in the human genome, and we showed that these are a significant source of structural variation (Huang et al., 2010). Since that time, our group has continued to develop high throughput tools to characterize these understudied sequences in genomes and to describe the expression and genetic stability of interspersed repeats in normal and malignant tissues. We have developed a monoclonal antibody to one of the proteins encoded for by Long INterspersed Element-1 (LINE-1) and showed its aberrant expression in a wide breadth of human cancers (Rodi? et al., 2014). We have demonstrated acquired LINE-1 insertion events during the evolution of metastatic pancreatic ductal adenocarcinoma and other gastrointestinal tract tumors (Rodi? et al., 2015). We have major projects focused on studying functional consequences of inh...erited sequence variants, and exciting evidence that these predispose to cancer risk and other disease phenotypes. Our laboratory is using a combination of genome wide association study (GWAS) analyses, custom RNA-seq analyses, semi-high throughput gene expression reporter assays, and murine models to pursue this hypothesis. 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

  • Zhiping Li Lab

    The Zhiping Li Lab focuses on the pathogenesis of nonalcoholic fatty liver disease and immune-mediated liver injury. Our active research focuses on the dietary modulation of gut bacteria, liver innate immune system and their regulation on tissue injury and repair. Clinical research from the lab focuses on cirrhotic ascites, liver transplant, hepatocellular carcinoma and immune-mediated liver diseases as well as endoscopic techniques and interventions.

    Research Areas: gastrointestinal system, gut bacteria, nutrition, obesity, pathogenesis, liver diseases

  • Zsuzsanna McMahan Lab

    The Zsuzsanna McMahan Lab conducts translational research that seeks to identify the novel antigens in scleroderma and to define the target tissue in this disease. We are conducting two active clinical research trials, including one that studies skin biopsy specimens as biomarkers of scleroderma and the response to mycophenolate mofetil (MMF or Cellcept). The other study is a gastrointestinal involvement registry that follows patients who are experiencing GERD, small bowel bacterial overgrowth, constipation, fecal incontinence and gastroparesis to see if there is improvement in symptoms after a change in treatment is implemented.
