Total RNA was extracted and used to generate Affymetrix expression array profiles. For each racial group collected samples were either controls (no history of BE or EAC) or those with a history of BE (Barrett's Esophagus) and/or EAC (esophageal adenocarcinoma). This allowed us to identify gene with tissue specific expression differences between the two racial groups, as well as those that differed between control and disease groups.2019/02/01GSE77563GSM2054527GSM2054505GSM2054528GSM2054506GSM2054529GSM2054507GSM2054508GSM2054523GSM2054524GSM2054525GSM2054526GSM2054504GSM2054541GSM2054520GSM2054542GSM2054543GSM2054521GSM2054522GSM2054540GSM2054509GSM2054538GSM2054516GSM2054517GSM2054539GSM2054518GSM2054519GSM2054534GSM2054512GSM2054535GSM2054513GSM2054514GSM2054536GSM2054537GSM2054515GSM2054530GSM2054531GSM2054532GSM2054510GSM2054511GSM20545331769277563Homo sapiens[30578782]
