Endoplasmic reticulum (ER) is the organelle where most secreted and transmembrane proteins fold and mature. Endoplasmic reticulum stress can occur when endoplasmic reticulum cannot fold with various high-rate proteins. Endoplasmic reticulum stress is inherently related to the disturbance of liver homeostasis. Activation of endoplasmic reticulum stress induces ketosis, hepatic fat deposition and insulin resistance in dairy cows, all of which may lead to or further aggravate liver injury in dairy cows. In recent years, more and more attention has been paid to the role and mechanism of endoplasmic reticulum stress in various pathological conditions of dairy cows. Therefore, this paper reviewed the effects of endoplasmic reticulum stress on liver injury in dairy cows, and elucidated the mechanism of endoplasmic reticulum stress on liver injury in dairy cows from three aspects: cow ketosis, fatty liver and insulin resistance.
Key words: dairy cows; endoplasmic reticulum stress; liver injury
