1. Isolated and Combined Remethylation Disorders: Biochemical and Genetic Diagnosis and Pathophysiology
Abstract Genetic defects affecting the remethylation pathway cause hyperhomocysteinemia. Isolated remethylation defects are caused by mutations of the 5, 10-methylenetetrahydrofolate reductase (MTHFR), methionine synthase reductase(MTRR), methionine synthase(MTR), and MMADHC genes, and combined remethylation defects are the result of mutations in genes invol

2. Adiponectin is protective against endoplasmic reticulum stress-induced apoptosis of endothelial cells in sepsis
Endoplasmic reticulum (ER) stress is a critical molecular mechanism involved in the pathogenesis of sepsis. Hence, strategies for alleviating this stress may be essential for preventing cardiovascular injuries under sepsis. Adiponectin is secreted by adipocytes and its levels are decreased in sepsis. The purpose of this study was to investigate the protectiv

3. α-Linolenic acid prevents hepatic steatosis and improves glucose tolerance in mice fed a high-fat diet
OBJECTIVES: Dietary omega-3 fatty acids have been efficacious in decreasing serum cholesterol levels and reducing the risk of cardiovascular disease. However, the metabolic and molecular changes induced by the omega-3 fatty acid α-linolenic acid (ALA), which is found in linseed oil, are not fully understood. In this study, we showed a correlation between A

4. Comparison of endoplasmic reticulum stress and mitochondrial biogenesis responses after 12 weeks of treadmill running and ladder climbing exercises in the cardiac muscle of middle-aged obese rats
The purpose of the present study was to compare the influence of aerobic exercise (AE) lasting 12 weeks to that of resistance exercise (RE) of the same duration on endoplasmic reticulum (ER) stress and mitochondrial biogenesis in the cardiac muscle of middle-aged obese rats. Obesity was induced in thirty 50-week-old male Sprague Dawley rats over 6 weeks by a

5. Impact of propofol on renal ischemia/reperfusion endoplasmic reticulum stress
Abstract Purpose: To investigate the protective mechanisms of propofol (Pro) on renal ischemia/reperfusion (I/R) injury by studying its impact on renal I/R endoplasmic reticulum stress. Methods: Eighteen male Sprague-Dawley rats (SD rats) were randomly divided into three groups: the I/R group, the Pro pretreatment group, and the control group, and corresp

6. Hypothalamic endoplasmic reticulum stress of overtrained mice after recovery
Abstract AIMS knowing the relationship between endoplasmic reticulum (ER) stress and inflammation and based on the fact that downhill running-based overtraining (OT) model increases hypothalamus levels of some pro-inflammatory cytokines, we verified the effects of three OT protocols on the levels of BiP, pIRE-1 (Ser734), pPERK (Thr981), pelF2alpha (Ser52),

7. Endoplasmic reticulum stress and renal lesion in mice with combination of high-fat diet and streptozotocin-induced diabetes
ABSTRACT PURPOSE : To investigate in the kidney the pathologic changes and expression of GRP78 and CHOP in the Kunming (KM) mice with combination of high-fat diet and streptozotocin-induced diabetes. METHODS : Sixty two male KM mice were randomly divided into a normal control (NC) group (n=20) and a high-fat diet (HFD) group (n=42). After a four-week dieta

8. Inibição do estresse do retículo endoplasmático restaura o conteúdo de ABCA-1 e o efluxo de colesterol em macrófagos tratados com albumina modificada por glicação avançada / Inhibition of endoplasmic reticulum stress restores the ABCA-1 protein level and cholesterol efflux in advanced glycated albumin-treated macrophages
Produtos de glicação avançada (AGE) prejudicam o metabolismo de lipoproteínas e o transporte reverso de colesterol, o que contribui para a aterosclerose no diabete melito (DM). Em particular, a albumina modificada por AGE (albumina-AGE) reduz a remoção de colesterol por diminuir o conteúdo do receptor ABCA-1 em macrófagos. Isto se vincula ao insulto

9. Indução do promotor GmNAC6 por elicitores de estresses e mapeamento de regiões reguladoras / Induction of the promoter GmNAC6 by elicitors of stress and mapping of regulatory regions
NAC domain-containing proteins are unique to plants and comprise a large gene family of transcriptional factors implicated in diverse aspects of plant development and stress responses. The GmNAC6 was recently identified as a downstream component of the ER (endoplasmic reticulum) stress- and osmotic stress-induced NRP (N-rich proteins)-mediated cell death sig

10. Disfunção na resposta ao estresse do retículo endoplasmático em linfócitos de pacientes com transtorno de humor bipolar
Bipolar disorder (BD) is a severe chronic psychiatric disorder that has been related to several cellular dysfunctions, such as an impaired endoplasmic reticulum (ER) stress response. We aimed to evaluate the unfolded protein response (UPR) and the outcome of this cellular process in cultured lymphocytes from patients with BD and healthy subjects, assessing i

11. A expressão deficiente das chaperonas GRP78 e GRP94 conecta a sinalização de TLR4 com o estresse de retículo endoplasmático / Chaperone insuficiency of GRP78 and GRP94 links TLR4 signaling to endoplasmic reticulum stress
TLR4 activation and the induction of endoplasmic reticulum stress (ERS) are two of the most important mechanisms connecting excessive fat with insulin resistance. Recently, it was shown that activation of TLR4 can, per se, induce ERS, suggesting that TLR4 is a primary event in the induction of the cellular stress that contributes to increased inflammatory ge

12. Análises moleculares das vias de sinalização de morte celular originadas no retículo endoplasmático / Molecular analyses of cell death pathways signalling originated in the endoplasmic reticulum
Abiotic and biotic stresses are responsible for major losses in agricultural productivity world wise. Therefore, the understanding of mechanisms of plant stress response and adaptation to such conditions should provide the foundation for engineering plant stress tolerance and hence maximizing the yield of crops growing under adverse environmental conditions.
