Intestinal secretory cell ER stress and inflammation.

Data from animal models and human inflammatory bowel diseases have implicated the ER (endoplasmic reticulum) stress pathway in intestinal inflammation. We have characterized the development of inflammation in Winnie mice in which ER stress arises due to a single missense mutation in the MUC2 mucin produced by intestinal goblet cells. This model has allowed us to explore the genesis of inflammat...

Hyperthermia Induces the ER Stress Pathway

BACKGROUND The ER chaperone GRP78/BiP is a homolog of the Hsp70 family of heat shock proteins, yet GRP78/BiP is not induced by heat shock but instead by ER stress. However, previous studies had not considered more physiologically relevant temperature elevation associated with febrile hyperthermia. In this report we examine the response of GRP78/BiP and other components of the ER stress pathway ...

Chrysotile induces ER stress in macrophages

Though the mechanisms for fibrosis development remain largely unknown, recent evidence indicates that endoplasmic reticulum (ER) stress and activation of the unfolded protein response (UPR) may act as an important fibrotic stimulus in diseased lungs. ER stress is observed in lungs of patients with idiopathic pulmonary fibrosis. In this study we evaluated if ER stress and the UPR was present in ...

Palmitate induces ER stress in myotubes

Endoplasmic reticulum (ER) stress is proposed as a novel link between elevated fatty acids levels, obesity and insulin resistance in liver and adipose tissue. However, it is unknown whether ER stress also contributes to lipid-induced insulin resistance in skeletal muscle, the major tissue responsible of insulin-stimulated glucose disposal. Here, we investigated the possible role of ER stress in...

IKKα controls ATG16L1 degradation to prevent ER stress during inflammation

Inhibition of the IκB kinase complex (IKK) has been implicated in the therapy of several chronic inflammatory diseases including inflammatory bowel diseases. In this study, using mice with an inactivatable IKKα kinase (IkkαAA/AA), we show that loss of IKKα function markedly impairs epithelial regeneration in a model of acute colitis. Mechanistically, this is caused by compromised secretion of c...
