The accumulation of TDP-43, a widely expressed nuclear protein that binds both DNA and RNA, causes RNA instability in nerve cells derived from patients with amyotrophic lateral sclerosis (ALS). That leads to disruption of energy and protein production, and eventually causes cells’ death. Those findings were described in the…

Researchers have detailed the structural changes that occur in the protein hnRNPA2 when it is mutated in diseases related to amyotrophic lateral sclerosis (ALS). The study, “Mechanistic View of hnRNPA2 Low-Complexity Domain Structure, Interactions, and Phase Separation Altered by Mutation and…

The active molecule of Petinutin (methsuximide), an anti-epileptic medication, eased motor deficits, extended the lifespan, and showed potent neuroprotective effects in a worm model of amyotrophic lateral sclerosis (ALS), suggesting a potential new treatment strategy for multiple neurodegenerative diseases, a study reports. The study, “α-Methyl-α-phenylsuccinimide ameliorates neurodegeneration…
