Gene expression analysis in a transgenic Caenorhabditis elegans Alzheimer's disease model.

We have engineered transgenic Caenorhabditis elegans animals to inducibly express the human beta amyloid peptide (Abeta). Gene expression changes resulting from Abeta induction have been monitored by cDNA hybridization to glass slide microarrays containing probes for almost all known or predicted C. elegans genes.
