[original description: Non-steroidal anti-inflammatory drugs (NSAIDs) are used extensively as therapeutic agents, despite their well-documented gastrointestinal (GI) toxicity. Presently, the mechanisms responsible for NSAID-associated GI damage are incompletely understood. In this study, we used microarray analysis to generate a novel hypothesis about cellular mechanisms that underlie the GI toxicity of NSAIDs. Monolayers of intestinal epithelial; cells (IEC-6) were treated with NSAIDs that either [inhibit] (indomethacin, NS-398) or lack (SC-560) inhibitory effects on intestinal epithelial cell migration. Bioinformatic analysis of array data suggested that NSAIDs with adverse GI effects either decrease the gene expression of the calpains or increase the gene expression of the endogenous calpain inhibitor calpastatin. Calpains have been shown previously to modulate the migration of a variety of cells in different physiological contexts. Our experimental results suggest that the altered expression of calpain genes may contribute to the adverse effects of NSAIDs on intestinal; epithelial restitution. Microarray analysis has generated the novel hypothesis that the GI toxicity of NSAIDs may be attributed in part to drug-induced changes in the expression and activity of calpains. Experiment Overall Design: Monolayers of intestinal epithelial cells (IEC-6) were treated with NSAIDs that either exhibit (indomethacin, NS-398) or lack (SC-560) inhibitory effects on intestinal epithelial cell migration. Samples were then pooled to obtain sufficient material for gene array analysis. The pooled samples were used to hybridize 4 gene array chips for each biological sample.]" Comment[Study Grant Number] "" Comment[Study Funding Agency] "" Study Submission Date "" Study Public Release Date "2009-03-27" Study File Name "s_E-GEOD-7584_study_samples.txt" STUDY DESIGN DESCRIPTORS Study Design Type "unknown_experiment_design_type" "transcription profiling by array" Study Design Type Term Accession Number "" "" Study Design Type Term Source REF "" "" STUDY PUBLICATIONS Study PubMed ID "18281595" Study Publication DOI "10.1124/jpet.107.127720" Study Publication Author List "Raveendran NN, Silver K, Freeman LC, Narvaez D, Weng K, Ganta S, Lillich JD."
