Project description:Profiles of esophageal squamous cell carcinoma and normal esophageal normal epithelium normal cell line. Analysis provides validation of novel microRNA targets prediction algorithms.
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:ESCC tumor tissues possessed a significantly higher expression of CDKL3 than matched adjacent normal tissues. CDKL3 acts as a new oncogene in ESCC cell line TE-1. However, the molecular mechanisms and biological effects of CDKL3 in esophageal squamous cell carcinoma (ESCC) remain unknown. We used microarrays to elucidate the molecular mechanisms through which CDKL3 promotes the proliferation of ESCC cancer cells.
Project description:To identify candidate genes involved in enhanced tumorigenicity and metastasis of CD90+ esophageal tumor-initiating cells. The esophageal squamous carcinoma cell (ESCC) cell line KYSE-140 was sorted into CD90+ and CD90- populations by flow cytometry. Total RNA was analyzed on Affymetrix Human Genome U133 Plus GeneChip 2.0 arrays.
Project description:Chemotherapy resistance adversely impacts the treatment of some individuals with esophageal cancer. Identifying chemotherapy resistance might help tailor clinical treatments. In this study the impact of microRNAs on chemotherapy resistance in esophageal cancer was investigated. We used microarrays to detail the global programme of microRNA expression underlying chemotherapy resistance and identified distinct classes of up-regulated microRNAs in generated chemotherapy resistant cell lines. An in-vitro model of acquired chemotherapy resistance in esophageal adeno- (EAC) and squamous cell carcinoma (SCC) cells was used, and microRNA expression profiles for cisplatin or 5-fluorouracil (FU) resistant variants vs. chemotherapy sensitive controls were compared using microarray. These results were further validated using qRT-PCR techniques (not shown in this submission).
Project description:To identify differentially expressed genes by anti cancer treatments (microRNAs or siRNAs) in human cancer, several cell lines (pancreatic cancer, esophageal cancer, tongue squamous cell carcinoma, hypopharyngeal squamous cell carcinoma and lung squamous cell carcinoma) were subjected to Agilent whole genome microarrays.
Project description:Expression profiles of immortal esophageal squamous cancer cell lines were compared with those of cultured mortal noncancerous esophageal epithelial cells. Keywords: Cell type comparison
