BACKGROUND The endoplasmic reticulum plays an important role in many cellular processes, which includes protein synthesis, folding and post-translational processing of newly synthesized proteins. It is also the site for quality control of misfolded proteins and entry point of extracellular proteins to the secretory pathway. Hence at any given point of time, endoplasmic reticulum contains two di...

Triple negative breast cancer (TNBC) is a that aggressive with short survival rate. In comparison to other subtypes, TNBC tumors are bigger, more chemo resistant, highly proliferative, and usually abundant in stem immune cells. These modifications functionally dependent on high-quality endoplasmic reticulum mitochondrial pool. Endoplasmic health monitored enhanced regular basis via dynamics. Th...

Obesity and elevated cytokine secretion result in a chronic inflammatory state and may cause the insulin resistance observed in type 2 diabetes. Recent studies suggest a key role for endoplasmic reticulum stress in hepatocytes and adipocytes from obese mice, resulting in reduced insulin sensitivity. To address the hypothesis that thiazolidinediones, which improve peripheral insulin sensitivity,...

Spinal and bulbar muscular atrophy is an X-linked degenerative motor neuron disease caused by an abnormal expansion in the polyglutamine encoding CAG repeat of the androgen receptor gene. There is evidence implicating endoplasmic reticulum stress in the development and progression of neurodegenerative disease, including polyglutamine disorders such as Huntington's disease and in motor neuron di...

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...

The disruption of endoplasmic reticulum function leads to an accumulation of unfolded proteins, which results in endoplasmic reticulum stress. In the present study, we investigated the effect of vanadate on such stress. Endoplasmic reticulum stress increased glucose-regulated protein 78 (GRP78) and CCAAT/enhancer-binding protein homologous protein (CHOP) expressions in glial cell cultures. We f...

background: the ultrastructural analysis of cultured follicles could direct us to understand subcellular changes during in vitro culture. objective: this study was done to verify the ultrastructural characteristics of in vitro cultured mouse isolated preantral follicles in co-culture system in the presence and absence of leukemia inhibitory factor (lif) materials and methods: mechanically isola...

Endoplasmic reticulum stress has been linked to insulin resistance in multiple tissues but the role of endoplasmic reticulum stress in skeletal muscle has not been explored. Endoplasmic reticulum stress has been reported to increase tribbles 3 expression in multiple cell lines. Here, we report that high-fat feeding in mice, and obesity and type 2 diabetes in humans significantly increases tribb...
