Transcription profiling of mouse olfactory epithelium frpm Harlequin mutants compared to littermate controls


ABSTRACT: Microarray analysis of gene expression in the olfactory epithelium of Harlequin mouse as a model of oxidative-stress induced neurodegeneration of olfactory sensory neurons Experiment 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.

Oxidative stress in the olfactory system is a major factor associated with age-related olfactory impairment, although the mechanisms by which this occurs are not completely understood. The Harlequin mutant mouse (Hq/Y), which carries an X-linked recessive mutation in the Aifm1 gene, is a model of progressive oxidative stress-induced neurodegeneration in the cerebellum and retina. To determine whether the Hq/Y mutant mouse is a suitable model of oxidative stress-associated olfactory aging, we inv  ...[more]
