Proteasome Dysfunction Activates Autophagy and the Keap1-Nrf2 Pathway

Abstract excerpt

The ubiquitin-proteasome system and autophagy are crucially important for proteostasis in cells. These pathways are interdependent, and dysfunction in either pathway causes accumulation of ubiquitin-positive aggregates, a hallmark of human pathological conditions. To elucidate in vivo compensatory action(s) against proteasomal dysfunction, we developed mice with reduced proteasome activity in their livers. The...
