Project description:This SuperSeries is composed of the following subset Series: GSE19566: Genomic profiling of gastric carcinoma in situ by array-based comparative genomic hybridization GSE19574: Genomic profiling of gastric adenomas by array-based comparative genomic hybridization Refer to individual Series
Project description:In this study, we investigated CNAs of 20 gastric CIS (Vienna category 4.2) and 20 adenomas, including 7 low-grade adenomas (LGA; Vienna category 3) and 13 high-grade adenomas (HGA; Vienna category 4.1), by 244k oligonucleotide-based array comparative genomic hybridization (array CGH). 20 gastric carcinoma in situ (CIS) vs. 20 controls. The supplementary file 'GSE19566_aberrations.txt' file contains a summary of the aberrations in the gastric CISs as determined by the ADM-2 algorithm.
Project description:In this study, we investigated amplifications and deletions of 49 gastric cancer cell lines by 244k oligonucleotide-based array comparative genomic hybridization.
