Research Lab Results for neoplasms
Brain Tumor Cancer Genetics LabLab WebsitePrincipal Investigator:
Chetan Bettegowda, M.D., Ph.D.
The lab explores the genetic underpinnings that drive the pathogenesis of a variety of primary ...central nervous system neoplasms. We are interested in exploiting genetic changes for both diagnostic and therapeutic purposes. Our lab is currently working on understanding the extreme responders and extreme clinical phenotypes of brain and spinal cord tumors to identify factors that may modulate responses to therapy. view moreResearch Areas: brain tumor genetics, brain tumor
Braunstein LabLab WebsitePrincipal Investigator:
Evan Braunstein, M.D., Ph.D.
Dr. Braunstein's research focuses on inherited predisposition to hematologic diseases. His labo...ratory studies the inherited genetic changes in DNA that increase susceptibility to disease. Blood cancers such as myeloproliferative neoplasms and myelodysplastic syndromes are traditionally thought to be acquired disorders, however there is increasing evidence that inherited genetic changes play a role. In addition, Dr. Braunstein studies non-malignant blood diseases including atypical hemolytic uremic syndrome (aHUS) and related thrombotic disorders such as APLS, TTP and HELLP syndrome which are caused in part by genetic mutations. His work has identified a germline variants in the ERBB genes that predispose to hematologic malignancies. In addition, his research group found that patients with catastrophic APLS and HELLP syndrome frequently harbor germline mutations in complement regulatory genes. This has led directly to clinical trials designed to test the efficacy of complement inhibition in patients with these disorders. Dr. Braunstein continues to work toward translating the scientific findings from the laboratory into improved care and treatment for patients. view moreResearch Areas: Myeloproliferative neoplasms, complement disorders
GI Biomarkers LaboratoryPrincipal Investigator:
Stephen Meltzer, M.D.
The GI Biomarkers Laboratory studies gastrointestinal cancer and pre-cancer biogenesis and biom...arkers. The lab is led by Dr. Stephen Meltzer, who is known for his research in the molecular pathobiology of gastrointestinal malignancy and premalignancy. Research in the lab has led to several groundbreaking genomic, epigenomic and bioinformatic studies of esophageal and colonic neoplasms, shifting the gastrointestinal research paradaigm toward genome-wide approaches. view moreResearch Areas: gastrointestinal system, translational research in Barrett’s esophagus-associated neoplastic progression, Molecular pathophysiology, biomarkers, cancer, epigenetics, genomics, bioinformatics, biogenesis
GI Early Detection Biomarkers LabPrincipal Investigator:
Stephen Meltzer, M.D.
Dr. Meltzer is an internationally renowned leader in the molecular pathobiology of gastrointest...inal malignancy and premalignancy. He invented molecular methods to detect loss of heterozygosity in tiny biopsies, triggering an avalanche of research on precancerous lesions. He was the first to comprehensively study coding region microsatellite instability, leading to the identification of several important tumor suppressor genes. He performed several groundbreaking genomic, epigenomic and bioinformatic studies of esophageal and colonic neoplasms, shifting the GI research paradigm toward genome-wide approaches. He directed an ambitious nationwide validation study of DNA methylation-based biomarkers for the prediction of neoplastic progression in Barrett’s esophagus.Research Areas: gastrointestinal cancer, gastrointestinal
Dr. Meltzer founded and led the Aerodigestive Cancer and Biomarker Interdisciplinary Programs at the University of Maryland, also becoming associate director for core sciences at that school’s Cancer Center. He currently holds an endowed professorship and is the director of GI biomarker research at Johns Hopkins.
The laboratory group focuses its efforts on the molecular genetics of gastrointestinal cancers and premalignant lesions, as well as on translational research to improve early detection, prognostic evaluation, and treatment of these conditions. Below, some examples of this work are described. view more
Marcia Canto LabPrincipal Investigator:
Marcia Canto, M.D., M.H.S.
Research interests in the Marcia Canto Lab include pancreatic neoplasms, Barrett’s esophagus an...d endomicroscopy. We are also interested in the use of endoscopic ultrasound to identify early-stage pancreatic cancer and its precursors. view moreResearch Areas: endomicroscopy, Esophageal Disorders, pancreatic cancer, endoscopy, Barrett's esophagus
