Project description:This SuperSeries is composed of the following subset Series: GSE19182: Gene expression profiling of differentiated HNECs stimulated by IL4, IL13, IFNalpha, IFNbeta, IFNgamma and controls GSE19187: Nasal epithelium gene expression profiling in child respiratory allergic disease Refer to individual Series
Project description:The aim of this study was to identify differences in the NK-cell response towards Leishmania mexicana lipophosphoglycan (LPG) between patients with localized (LCL) and diffuse (DCL) cutaneous leishmaniasis through gene expression profiling, in an attempt to pinpoint alterations in the signaling pathways responsible for the NK-cell dysfunction in patients with DCL. To determine the gene expression profiling in non stimulated and LPG-stimulated NK cells we include samples of controls, LCL and DCL patients. We performed microarrays (Human Gene 1.0 ST, Affymetrix) to identify differentially expressed transcripts between non stimulated and LPG-stimulated NK cells between controls, LCL and DCL samples.
Project description:RATIONALE: Studying the genes expressed in samples of tissue from patients with cancer may help doctors identify biomarkers related to cancer.
PURPOSE: This laboratory study is using gene expression profiling to evaluate normal tissue and tumor tissue from patients with colon cancer that has spread to the liver, lungs, or peritoneum.
Project description:Skeletal muscle is the key site of peripheral insulin resistance in type 2 diabetes. Insulin-stimulated glucose uptake is decreased in differentiated diabetic myotubes in keeping with a retained genetic/epigenetic defect of insulin action. Microarray analysis was used to investigate differences in gene expression with differentiation in diabetic cultures compared to controls.
