Project description:Human SH-SY5Y neuroblastoma cells treated with paraquat, a neurotoxic herbicide which both catalyzes the formation of reactive oxygen species (ROS) and induces mitochondrial damage in animal models was profiled using Affimetrix Exon 1.0 ST GeneChips® Human SH-SY5Y neuroblastoma cells was compared with respect to Human SH-SY5Y neuroblastoma cells treated with Paraquat. Parqaut treatment was done as described by Maracchioni, A., Totaro, A., Angelini, D.F., Di Penta, A., Bernardi, G., Carri, M.T., and Achsel, T. (2007) J Neurochem 100, 142-153

Project description:The deposition of unconjugated bilirubin (UCB) in selected regions of the brain results in irreversible neuronal damage, or Bilirubin Encephalopathy (BE). Although UCB impairs a large number of cellular functions, the basic mechanisms of neurotoxicity have not yet been fully clarified. While cells can accumulate UCB by passive diffusion, cell protection may involve multiple mechanisms including the extrusion of the pigment as well as pro-survival homeostatic responses that are still unknown. The effects of UCB treatment to SH-SY5Y neuroblastoma cell line were examined by high-density oligonucleotide microarrays. 230 genes were induced after 24 hours. A Gene Ontology (GO) analysis showed that a large group of UCB-induced genes were components of the ER stress response. Independent experimental validation of molecular events crucial for the ER stress response is presented. The results show that UCB exposure induces the ER stress response as a major intracellular homeostatic response in neuroblastoma cells in vitro. Our finding may provide valuable information for new therapeutic strategies in the treatment of BE. Experiment Overall Design: We used high-density oligonucleotide microarrays to analyze the gene expression profile of human neuroblastoma SH-SY5Y cells upon UCB treatment. Three replicates of UCB-treated cells were analyzed. As controls, we used three replicates of the same cells treated with DMSO only (the solvent used for UCB treatment).

Project description:Mitochondrial dysfunction has been directly or indirectly implicated in the pathogenesis of a number of neurodegenerative disorders including Parkinson's disease, Alzheimer's disease and Amyotrophic Lateral Sclerosis (ALS). We used exon-sentive microarrays to characterize the responses to different mitochondrial perturbations in cellular models. We examined human SH-SY5Y neuroblastoma cells treated with paraquat, a neurotoxic herbicide which both catalyzes the formation of reactive oxygen species (ROS) and induces mitochondrial damage in animal models, and SH-SY5Y cells stably expressing the mutant SOD1(G93A) protein, one of the genetic causes of ALS. We identified a common set of genes that have a deregulated transcription and alternative splicing in both models. Noticeably, pathway analysis revealed that the expression of a subset of genes involved in neuritogenesis and axon guidance is perturbed, suggesting that alterations of axonal function may descend directly from mitochondrial damage and be responsible for neurodegenerative conditions. This SuperSeries is composed of the SubSeries listed below.
