Microarray gene expresion analysis for early and advanced gastric adenocarcinoma vs normal adjacent tissue.
The study aimed to understand gradual biological variations during gastric tumorigenesis, and to identify the candidate genes that are involved in tumor progression and metastasis. cDNA microarray data were obtained from 10 pair of cancerous and normal adjacent tissue from gastric adenocarcinoma patients. As a results, we found that 136 genes were up-regulated and 96 genes were down-regulated by at least four-fold in tumor tissue. The analysis of gene clusters revealed a complex remodelling of n...

Deep data QC
metadata only · no data-level QC for this typeStandardized, field-standard QC computed by touching the data — every metric states how it was obtained
No quantitative QC rubric exists for this data type yet, so it is deliberately left unscored — this is an honest "not applicable", not a poor rating.
