Gene expression profile in Barrett's esopahgus. Homo sapiens

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) Overall design: 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.
