Project description:Organophosphorus compounds induce cardiotoxicity through currently unknown mechanisms, which need to be unraveled by a comprehensive and systematic approach such as genome-wide gene expression analysis. We used microarrays to study gene expression changes in human cardiomyocytes after exposure to VX, and identified pathways underlying these changes. Human cardiomyocytes were exposed to sublethal concentrations (0, 0.1, 10 μM) of VX. RNA were extracted at different timepoints (0, 6, 24, 72 h) after VX exposure and hybridized to Affymetrix microarrays. Four biological repeats were used for each condition.
Project description:Chemical warfare nerve agents (CWNA) are potent cholinesterase inhibitors that may also have non-cholinesterase effects. Several in vivo studies have shown that exposure to CWNA compounds induces damage in the brain and heart. Underlying mechanisms of this damage are a critical area of research for the development of medical countermeasures. This study utilized microRNA (miRNA) analysis to evaluate potential direct cellular effects of the nerve agent VX (o-ethyl-s-[2 (diisopropylamino) ethyl]) on human (iPSC)-derived neurons and iPSC-derived cardiomyocytes. iPSC-derived cardiomyocytes were treated with VX at concentrations of 0µM (saline control), 0.1µM or 100µM for either 1 hour or 6 hours. Total RNA was then isolated and processed for miRNA microarray analysis using Affymetrix miRNA 2.0 GeneChips

Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.

Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression.
Project description:Organophosphorus compounds induce hepatotoxicity through currently unknown mechanisms, which need to be unraveled by a comprehensive and systematic approach such as genome-wide gene expression analysis. We used microarrays to study gene expression changes in human hepatocytes after exposure to VX, and identified pathways underlying these changes. Human hepatocytes were exposed to sublethal concentrations (0, 0.1, 10 μM) of VX. RNA were extracted at different timepoints (0, 6 h) after VX exposure and hybridized to Affymetrix microarrays. Four biological repeats were used for each condition.
