Frozen tumour samples of 131 gastric cancer patients [array CGH]. Homo sapiens

We sought to illustrate molecular subtypes associated with clinical prognosis and to identify genetic aberrations for potential targeted therapeutics through comprehensive whole-genome analysis of 131 Chinese gastric cancer tissue specimens using whole-genome array CGH. Overall design: We profiled 131 Chinese gastric cancer genomes using Agilent 244K array CGH technology. 70 samples Among them were further profiled by Affymetrix Hu133Plus2 arrays for mRNA expression.
