Description of Project:

Mutations in the ubiquitously expressed SOD1 gene are a cause familial ALS. Transgenic mice carrying SOD1G93A mutations develop an adult onset form of lethal motor neuron disease. The proto-oncoprotein c-Jun is involved in neuronal survival and regeneration and its presence at increased levels in the spinal motoneurons of ALS patients and mouse models suggests it may play a role in this neurodegenerative disease. To study the role of c-jun in ALS, we crossed conditional mouse mutants lacking c-jun in the CNS with transgenic SOD1G93A mice. Our preliminary data demonstrates that the deletion of c-jun results in a significant increase in lifespan and reduction in ALS pathology in SODG93A mice. Further investigations will concentrate on the cellular and molecular mechanisms through which c-jun deletion is neuroprotective and in the possible pharmacological interventions against c-jun that may ameliorate ALS pathology.
