Low Levels of Specific microRNA Linked to Nerve Cell Damage and ALS Progression in Early Study

Lower-than-usual levels of a molecule called miR126-5p — a type of microRNA, with a role in producing proteins — led to neuron degeneration and disease progression in a mouse model of amyotrophic lateral sclerosis (ALS), in part by working to raise levels of toxic molecules, a study reports. Its researchers…
