TDP-43 nuclear loss in FTD/ALS causes widespread alternative polyadenylation changes
bioRxiv the preprint server for biology(2024)
Abstract
In frontotemporal dementia and amyotrophic lateral sclerosis, the RNA-binding protein TDP-43 is depleted from the nucleus. TDP-43 loss leads to cryptic exon inclusion but a role in other RNA processing events remains unresolved. Here, we show that loss of TDP-43 causes widespread changes in alternative polyadenylation, impacting expression of disease-relevant genes (e.g., ELP1, NEFL, and TMEM106B ) and providing evidence that alternative polyadenylation is a new facet of TDP-43 pathology.
