Investigating the Role of TDP-43 in Polyglutamine Toxicity
EF 2012-13
Résumé
Mutations in TDP-43 (TAR DNA-binding Protein) and FUS (Fused in Sarcoma) have been identified in patients with Amyotrophic Lateral Sclerosis (ALS) and Frontotemporal dementia, while TDP-43 and FUS protein accumulations are observed in a growing number of neurodegenerative including Huntington's Disease (HD). My preliminary data shows that reducing TDP-43 and FUS activity rescues toxicity in worm and mammalian polyglutamine (polyQ) models. Based on my genetic analyses with worms the mechanism may rest with (1) Increased proteotoxic stress within the Endoplasmic Reticulum (ER) and/or (2) Inappropriate regulation of TDP-43/FUS target RNAs. I request support to investigate the molecular basis of TDP-43, FUS and huntingtin toxicity in primary neuronal culture from CAG140 knock-in mice.
