Project description:To characterize genomic instability in esophageal squamous cell carcinoma, we examined loss of heterozygosity, copy number loss, and copy number gain in ESCC patients from a high-risk region of China.
Project description:To characterize genomic instability in esophageal squamous cell carcinoma, we examined loss of heterozygosity, copy number loss, and copy number gain in ESCC patients from a high-risk region of China. Affymetrix SNP arrays were performed according to the manufacturer's directions on DNA extracted from microdissected esophageal squamous cell carcinoma samples or peripheral blood samples. Tumor DNA samples were normalized individually to the set of 102 peripheral blood samples. Copy number variations and loss of heterozygosity were determined by a paired analysis of tumor and blood DNA from the same individual.
Project description:Analysis of primary esophageal squamous cell carcinoma (ESCC) from 71 patients in japan. Integrative analysis of gene expression profiles and genomic alterations obtained from array-CGH and NGS provided us new insight into the pathogenesis of ESCC
Project description:To understand the difference of protein expression between paired esophageal squamous cell carcinoma (ESCC) and adjacent normal tissues, we collected 10 paired ESCC and normal tissues from surgical resected specimems for high-throughput proteomic experiments. From comparative analysis, the dysregulated signaling pathways in ESCC could be uncovered.
Project description:Copy number analysis of primary esophageal squamous cell carcinoma (ESCC) from 40 patients in Japan. Integrative analysis of gene expression profiles and genomic alterations obtained from array-CGH and NGS provided us new insight into the pathogenesis of ESCC.
Project description:Our aim is to identify frequent genomic aberrations both in ESCC and esophageal dysplasia, and to discover important copy number-driving genes and microRNAs in ESCC. We carried out array-based comparative genomic hybridization (array CGH) on 59 ESCC resection samples and 16 dysplasia biopsy samples. Expression of genes at 11q13.3 was analyzed by real-time PCR and immunohistochemistry (IHC). Integrated analysis was performed to identify genes or microRNAs with copy number-expression correlations. Two group experiment, esophageal dysplasia vs. esophageal squamous cell carcinoma. Biological replicates: 16 dysplasias vs. 59 carcinomas
Project description:This study was designed to identify genes aberrantly expressed in esophageal squamous cell carcinoma (ESCC) cells. Three esophageal squamous cell carcinoma-derived cell lines and one normal human esophageal squamous cell line were analyzed.
Project description:Genomic instability plays an important role in human cancers. We previously characterized genomic instability in esophageal squamous cell carcinomas (ESCC) in terms of loss of heterozygosity (LOH) and copy number (CN) changes in tumors. In the current study we focus on biallelic loss and its relation to expression of mRNA and miRNA in ESCC using results from 500K SNP, mRNA, and miRNA arrays in 30 cases from a high-risk region of China. 30 matched tumors and normal tissue
Project description:SAGE libraries made of squamous esophagus tissue, primary cell culture or esophageal squamous cell carcinoma Keywords: SAGE analysis of different tissues squamous esophagus biopsy was taken from 1 male metaplastic Barrett's esophagus patient. primary cell culture was from 1 male Barrett's esophagus patient. Esophageal squamous cell carcinoma was from a patient known to have ESCC
