Conversely, robust downregulation of both strands of miR-132 and miR-574 are found only in LCLs derived from patients with likely TDP-43 pathology, but not in LCLs carrying a mutation in SOD1. We could thus show that the known differences between SOD1 and non-SOD1 ALS regarding TDP-43 pathology [9] are also reflected at the level of TDP-43 binding miRNAs, at least in LCLs. This evidence concerns the gene SOD1 and amyotrophic lateral sclerosis.
