Epigenome signatures during gastric carcinogenesis based on next generation sequencing [Affymetrix]. Homo sapiens

Because gastric cancer cells already had genetic and epigenetic alterations which can affect the gastric carcinogenesis, we tried to characterize genetic and epigenetic changes during gastric carcinogenesis. To do this, we performed SNP array. Overall design: Copy number alteration profiles of gastric mucosa, intestinal metaplasia, and gastric cancer cells were generated by SNP6.0 Array.
