Endoplasmic reticulum stress regulates inflammation in adipocyte of obese rats via toll-like receptors 4 signaling
Objective(s): To explore whether endoplasmic reticulum (ER) stress regulates inflammation in adipose tissue of obese rats via TLR4 signaling. Materials and Methods: Sprague Dawley rats were randomly divided into four groups, and body weight, food intake, and free fatty acids (FFA) were measured. Real-time PCR and Western blot were used to determine mRNA or protein expression of TLR4, TRAF6, IKK...
متن کاملEndoplasmic reticulum stress induces leptin resistance.
Leptin is an important circulating signal for inhibiting food intake and body weight gain. In recent years, "leptin resistance" has been considered to be one of the main causes of obesity. However, the detailed mechanisms of leptin resistance are poorly understood. Increasing evidence has suggested that stress signals, which impair endoplasmic reticulum (ER) function, lead to an accumulation of...
متن کاملSeawater inhalation induces acute lung injury via ROS generation and the endoplasmic reticulum stress pathway
Seawater (SW) inhalation can induce acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). In the present study, SW induced apoptosis of rat alveolar epithelial cells and histopathological alterations to lung tissue. Furthermore, SW administration increased generation of reactive oxygen species (ROS), whereas pretreatment with the ROS scavenger, N‑acetyl‑L‑cysteine (NAC), signi...
متن کاملDegradation of the endoplasmic reticulum by autophagy during endoplasmic reticulum stress in Arabidopsis.
In this article, we show that the endoplasmic reticulum (ER) in Arabidopsis thaliana undergoes morphological changes in structure during ER stress that can be attributed to autophagy. ER stress agents trigger autophagy as demonstrated by increased production of autophagosomes. In response to ER stress, a soluble ER marker localizes to autophagosomes and accumulates in the vacuole upon inhibitio...
متن کاملEndoplasmic reticulum stress compromises the ubiquitin-proteasome system.
The presence of endoplasmic reticulum (ER) stress and impaired ubiquitin-proteasome system (UPS) activity has been independently implicated in the pathophysiology of conformational diseases. Here, we reveal a link between ER stress and the functionality of the UPS. Treatment of cells with different ER stressors delayed the degradation of an ER reporter substrate and caused a subtle but consiste...
