Gene expression profiling of Barrett's esophagus, adenocarcinoma, esophageal squamous epithelium and squamous cell carcinoma

Project description:The aim of this study is to generate and validate biomarkers to stratify patients with Barrett’s esophagus in terms of risk for developing cancer. We studied gene expression profiling in 69 frozen specimens, consisting of esophageal squamous epithelium from 19 healthy subjects, 20 specimens from patients with Barrett’s esophagus and 21 cases of esophageal adenocarcinoma, 9 cased of esophageal squamous cell carcinoma by whole genome microarray analysis. Laser capture microdissection technique was applied to procure cells from defined regions of Barrett’s esophagus metaplasia and esophageal adenocarcinoma. Microarray results were validated by quantitative real-time polymerase chain reaction (qRT-PCR) in an independent cohort consisting of 42 cases. Furthermore, immunohistochemistry was performed using antibodies to two selected target molecules on a third independent cohort of 36 specimens, consisting of 36 cases. A total of 1176 genes were associated significantly with esophageal adenocarcinoma. The expression pattern of a 4 gene signature with the highest discriminant score based on linear discriminant analysis (GeneSpring GX10.2), was identified and validated by qRT-PCR in independent cohort. Gene expression profiling of 20 specimens of Barrett's esophagus patients, 21 specimens of adenocarcinoma patients and 19 biopsies from patients with normal esophageal squamous epithelium, 9 specimens of squamous cell carcinoma were studied.

GLOBAL CHANGES IN GENE EXPRESSION OF BARRETT'S ESOPHAGUS COMPARED TO NORMAL SQUAMOUS ESOPHAGUS AND GASTRIC CARDIA TISSUES

Project description:Barrett’s esophagus (BE) is a metaplastic precursor lesion of esophageal adenocarcinoma (EA), the most rapidly increasing cancer in western societies. While the prevalence of BE is increasing, the vast majority of EA occurs in patients with undiagnosed BE. Thus, we sought to identify genes that are altered in BE compared to the normal mucosa of the esophagus, and which may be potential biomarkers for the development or diagnosis of BE. We performed gene expression analysis using HG-U133A Affymetrix chips on fresh frozen tissue samples of Barrett’s metaplasia and matched normal mucosa from squamous esophagus (NE) and gastric cardia (NC) in 43 BE patients.

microRNA expression in Barrett's esophagus and esophageal adenocarcinoma

Project description:Barrett's esophagus is a metaplastic condition of the distal esophagus, characterized by the replacement of normal squamous epithelium by columnar epithelium. Patients with BE have an increased risk of developing esophageal adenocarcinoma. MicroRNAs have been implicated to be disease and tissue specific, however limited data of microRNA expression in the esophagus is available. Therefore we evaluated microRNA expression profiles of esophageal adenocarcinoma and compared these with Barrett's esophagus and normal squamous esophagus.
