Obesity contributes to the development of type 2 diabetes, but the underlying mechanisms are poorly understood. Using cell culture and mouse models, we show that obesity causes endoplasmic reticulum (ER) stress. This stress in turn leads to suppression of insulin receptor signaling through hyperactivation of c-Jun N-terminal kinase (JNK) and subsequent serine phosphorylation of insulin receptor substrate–1 (IRS-1). Mice deficient in X-box–binding protein–1 (XBP-1), a transcription factor that… Expand
Inflammation and endoplasmic reticulum stress in obesity and diabetes
TLDR
ER stress and the related signaling networks present a critical mechanism underlying obesity-induced JNK activity, inflammatory response and insulin resistance. Expand
Endoplasmic reticulum stress and the c-Jun N-terminal kinase pathway in insulin resistance
Insulin resistance as well as pancreatic β-cell dysfunction is observed in type 2 diabetes. Recently, it has been shown that increase of endoplasmic reticulum (ER) stress and activation of the c-JunExpand
Chemically chaperoning the actions of insulin
TLDR
It is indicated that chemical chaperones improve glucose tolerance and insulin action in a mouse model of type 2 diabetes and offer a potential new target for therapeutic strategies designed to improve insulin action and glucose tolerance in diabetic individuals. Expand
Effects of triglyceride on ER stress and insulin resistance.
TLDR
The results of this study show that triglycerides is a central feature of peripheral insulin resistance, and also suggest that triglyceride-induced ER stress influences insulin resistance. Expand
Endoplasmic reticulum stress, obesity and diabetes.
TLDR
Ways in which ER stress operates as a common molecular pathway in the pathogenesis of obesity and diabetes are discussed. Expand
Deletion of Nck1 attenuates hepatic ER stress signaling and improves glucose tolerance and insulin signaling in liver of obese mice.
TLDR
The Src homology domain-containing adaptor protein Nck1, previously shown to modulate the UPR, is of functional importance in obesity-induced ER stress signaling and inhibition of insulin actions, which secondary to obesity impairs glucose homeostasis and insulin actions. Expand
The role of endoplasmic reticulum stress in hippocampal insulin resistance
TLDR
It is demonstrated for the first time that thapsigargin leads to ER stress and impaired insulin signaling in human hippocampal neurons, which suggests that ER stress may play a role in insulin resistance in the hippocampus. Expand

TLDR
Characterizing the mechanisms contributing to obesity and identifying potential targets for its prevention and treatment will have a great impact on the control of associated conditions, particularly T2D. Expand
The role for endoplasmic reticulum stress in diabetes mellitus.
TLDR
This review addresses the transition from physiology to pathology, namely how and why the physiological UPR evolves to a proapoptotic ER stress response and which defenses are triggered by beta-cells against these challenges. Expand
Chemical Chaperones Reduce ER Stress and Restore Glucose Homeostasis in a Mouse Model of Type 2 Diabetes
TLDR
It is demonstrated that chemical chaperones enhance the adaptive capacity of the ER and act as potent antidiabetic modalities with potential application in the treatment of type 2 diabetes. Expand

A central role for JNK in obesity and insulin resistance
TLDR
It is shown that JNK activity is abnormally elevated in obesity and an absence of JNK1 results in decreased adiposity, significantly improved insulin sensitivity and enhanced insulin receptor signalling capacity in two different models of mouse obesity. Expand
Reversal of Obesity- and Diet-Induced Insulin Resistance with Salicylates or Targeted Disruption of Ikkβ
TLDR
It is shown that high doses of salicylates reverse hyperglycemia, hyperinsulinemia, and dyslipidemia in obese rodents by sensitizing insulin signaling and identifies the IKKβ pathway as a target for insulin sensitization. Expand
Protection from obesity-induced insulin resistance in mice lacking TNF-α function
TLDR
Results indicate that TNF-α is an important mediator of insulin resistance in obesity through its effects on several important sites of insulin action. Expand

Findings suggest a special role for translational control in protecting secretory cells from ER stress in diabetes mellitus and exocrine pancreatic insufficiency. Expand
When translation meets metabolism: multiple links to diabetes.
TLDR
Progress in the understanding of endoplasmic reticulum overload by unfolded proteins has begun to uncover mechanisms leading to pancreatic beta- cell exhaustion, and future advances in this area may lead to identification of the missing links in the pathogenesis of beta-cell failures due to conditions such as hyperinsulinemia, hyperglycemia, and long-term treatment with sulfonylureas, and thus identify novel therapeutic targets for diabetes.
