Copy number variation analysis of human Barrett's esophagus stem cells (HumanOmniZhongHua-8 v1.1 Beadchip)

ABSTRACT: Barrett’s esophagus confers significant risk of esophageal adenocarcinoma. We have established the cloning system of patient-matched stem cells of Barrett’s esophagus and gastric cardia. Barrett's esophagus (BE) stem cells and gastric cardia (GC) stem cells from 12 patients were cloned. To analyze copy number variation in BE and GC stem cells, we have performed SNP array. It has shown that deletions such as p16 and FHIT in BE stem cells are significantly detected, while amplifications in BE stem cells are not. Also, we found some of BE stem cells did not share these deletions, suggesting emerging of BE does not require specific CNV.

Copy number variation analysis of human Barrett's esophagus stem cells (HumanOmniZhongHua-8 v1.1 Beadchip)

Project description:Barrettâs esophagus confers significant risk of esophageal adenocarcinoma. We have established the cloning system of patient-matched stem cells of Barrettâs esophagus and gastric cardia. Barrett's esophagus (BE) stem cells and gastric cardia (GC) stem cells from 12 patients were cloned. To analyze copy number variation in BE and GC stem cells, we have performed SNP array. It has shown that deletions such as p16 and FHIT in BE stem cells are significantly detected, while amplifications in BE stem cells are not. Also, we found some of BE stem cells did not share these deletions, suggesting emerging of BE does not require specific CNV. SNP array based copy number variation study was performed for BE and GC stem cells from human endoscopic biopsy (12 patients) to assess genomic stability at chromosomal level.

Cell cloning of Barrett's esophagus stem cell, gastric cardia stem cells and normal esophagus stem cells

Project description:Barrett’s esophagus confers significant risk of esophageal adenocarcinoma. We have established the cloning of patient-matched stem cells of Barrett’s, gastric, and esophageal epithelium. Barrett's esophagus stem cells (BE), gastric cardia stem cells (GC) and normal esophagus stem cells (Eso) from 12 patients were cloned (For BE: 12 patients, GC: 12 patients and Eso: 2 patients). Keratin 5 positive and Keratin 7 positive cells were cloned from human fetal esophageal epithelium. Using air liquid interface culture system, stem cells were induced to differentiate into mature epithelial structures.

Gene expression profile in Barrett's esopahgus

Project description:Microarray was used to identify differential gene expression pattern in Barrett's esophagus (BE), compared to the normal adjacent epithelia gastric cardia (GC) and normal squamous esophagus (NE) RNA was extraxted from endoscopic biopsies of BE (n=10), GC (n=10) and NE (n=10, only 8 uploaded). One NE sample was excluded since clustered with BE and all the intestinal markers were positive, indicating sampling error.

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.
