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.

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: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:To identify target genes of cancer-related microRNAs in human cancer, several cell lines (bladder cancer, prostate cancer, renal cell carcinoma, esophageal squamous cell carcinoma, and head and neck squamous cell carcinoma) were subjected to Agilent whole genome microarrays.
Project description:Eight different human cancer cell lines were cocultured with human cancer associated fibroblasts (CAF) as spheroid cultures. In another setup UT-SCC-7 cutaneous squamous cell carcinoma cells, together with human skin fibroblasts (SFB) and UT-SCC-2 cells together with gingival fibroblasts (GFB) were cultured as spheroid cocultures. These spheroids were treated with PAD4 or with citrullination buffer only. All spheroids were hypotonically lysed, and the remaining insoluble material was digested to peptides and analysed by LC-MS/MS.
Project description:By using gene chip technology, we can screen esophageal cancer invasion associated genes to understand esophageal squamous carcinoma invasion related mechanisms. Using the Transwell invasion chamber technology to establish human esophageal squamous carcinoma Eca109 and Eca109 - T4 cell lines with different invasion ability. Extracting Eca109 and Eca109-T4 total RNA, reverse transcribed into cDNA probes which labeled with Cy5 and Cy3 fluorescence, then it were hybridized with the Affymetrix gene chip. Using the Genechip- Scanner 3000 scan hybridization signal, and using the SAM 3.0 software analysis and process data.
