Expression data from esophageal squamous cell carcinoma patients. Expression data from esophageal squamous cell carcinoma patients

we conducted microarray experiments of 28 stage I-III ESCC patients based on Affymetrix Gene Chip Human Genome U133 plus 2.0 Array, performed enrichment analysis of differentially expressed genes (DEGs) as well as gene set enrichment analysis of all valid genes. Moreover, we summarized the secreted protein-encoding DEGs as well as esophagus-specific DEGs, hoping to offer some hints for early diagnosis and target for more efficacious treatment for ESCC in near future. Overall design: In total, there were 84 paired normal tissues, paratumor tissues, and tumor tissues from 28 ESCC patients were chosen to perform microarray analysis.
