Disruption of protein homeostasis plays an essential role in neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS). One strategy for restoring protein homeostasis and protecting neurons is to de-repress autophagy by disrupting the inhibitory BECN1/BCL2 complex, which has been shown to improve healthspan and lifespan in mice. We screened small molecule BH3 mimetics using an induced pluripotent stem cell (iPSC)-based model of ALS with a FUS mutation and identified obatoclax rescued neurons at by reducing cytoplasmic FUS levels, restoring protein homeostasis, and reducing degeneration.
