Expression data from olfactory epithelium of Harlequin mutant mice compared to littermate controls. Mus musculus

Microarray analysis of gene expression in the olfactory epithelium of Harlequin mouse as a model of oxidative-stress induced neurodegeneration of olfactory sensory neurons Keywords: comparison of gene expression level in unperturbed tissue of mutant vs. control mouse Overall design: Olfactory epithelium from Harlequin mutant mice and littermate control mice was microdissected for RNA extraction and hybridization on Affymetrix microarrays. We compared levels of gene expression in 6-month old mice to begin to identify mechanisms of oxidative-stress induced neurodegeneration and to correlate the cellular changes that we observed in the olfactory epithelium by using histology and immunohistochemistry with gene expression changes.
