Scientific Research

Iris Run for Refugees - February 2010

Current research interests of the laboratory include the elucidation of the growth factor-mediated transformation process of the enterochromaffin-like cell (ECL) in the Mastomys model of gastric neoplasia, as well as identification of molecular signatures that delineate gastrointestinal carcinoids. A multidisciplinary team has been established with collaborators from the Departments of Pathology and Mathematics, the HHMI Keck Institute (Affymetrix and Proteomics), and Medical Oncology at Yale University as well as with investigators in Norway, Germany, the United Kingdom and Israel. Established methodologies currently utilized include neuroendocrine cell isolation and enrichment, cell culture and in vitro analysis, Affymetrix gene profiling of rodent and human samples, real-time PCR, tissue microarray construction and analysis, and biostatistical data evaluation.



Mark Kidd, PhD

Laboratory Director

Major interests include the molecular pathobiology of gastric and small intestinal carcinoids. Principal focus is the characterization of molecular signatures that define malignancy.
