Targeting endoplasmic reticulum stress in liver disease

Fa-Ling Wu et al. Expert Rev Gastroenterol Hepatol. 2016 Sep.

Abstract

Introduction: The accumulation of unfolded protein in the endoplasmic reticulum (ER) initiates an unfolded protein response (UPR) via three signal transduction cascades, which involve protein kinase RNA-like ER kinase (PERK), inositol requiring enzyme-1α (IRE1α) and activating transcription factor-6α (ATF6α). An ER stress response is observed in nearly all physiologies related to acute and chronic liver disease and therapeutic targeting of the mechanisms implicated in UPR signaling have attracted considerable attention.

Areas covered: This review focuses on the correlation between ER stress and liver disease and the possible targets which may drive the potential for novel therapeutic intervention. Expert Commentary: We describe pathways which are involved in UPR signaling and their potential correlation with various liver diseases and underlying mechanisms which may present opportunities for novel therapeutic strategies are discussed.

Keywords: Endoplasmic reticulum stress; acute-on-chronic liver failure; alcoholic liver disease; drug-induced liver injury; hepatocellular carcinoma; nonalcoholic fatty liver disease; therapeutic target.
