TDP-43 levels in the brain tissue of ALS cases with and without C9ORF72 or ATXN2 gene expansions

Abstract excerpt

Objective To assess the amount of phosphorylated and nonphosphorylated TAR DNA-binding protein 43 (TDP-43) in the motor brain regions of cases of amyotrophic lateral sclerosis (ALS) with and without repeat expansions in the ATXN2 or C9ORF72 genes. Methods The 45-kDa phosphorylated form of TDP-43 and 43-kDa nonphosphorylated form of TDP-43 were quantified by immunoblot in postmortem brain tissue from the motor...
