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: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:Cancer cells express different sets of receptor type tyrosine kinases. These receptor kinases may be activated through autocrine or paracrine mechanisms. Fibroblasts may modify the biologic properties of surrounding cancer cells through paracrine mechansms. We used microarrays to obtain the global gene expression of human esophageal squamous cell carcinoma cell lines and various esophageal fibroblasts. A total of 22 human esophageal squamous cell carcinoma cell lines and fibroblasts were analyzed. 4 fibroblasts were obtained from surgically resected human esophagus. Cells were cultured under standard conditions, total RNA was extracted and hybridized on Affymetrix microarrays.
