High-intensity interval training (treadmill) effects in myokines and endoplasmic reticulum stress of calf muscles in obese mice

Int. j. morphol; 41 (2), 2023
SUMMARY: Obesity is commonly associated with chronic tissue inflammation and skeletal muscle dysfunction. The study aimed to investigate the effects of High-Intensity Interval training (HIIT) on myokines and endoplasmic reticulum (ER) stress of diet- induced obese (DIO) mice. Three-month-old C57BL/6 male...

Activación de sensores del estrés del retículo endoplásmico por dietas asociadas a enfermedades metabólicas y COVID-19

El retículo endoplásmico es un organelo abundante, dinámico y sensor de energía. Sus abundantes membranas, rugosa y lisa, se encuentran distribuidas en diferentes proporciones dependiendo del linaje y requerimiento celular. Su función es llevar a cabo la síntesis de proteínas y lípidos, y es el a...

Pin1 aggravates renal injury induced by ischemia and reperfusion in rats via Nrf2/HO-1 mediated endoplasmic reticulum stress

Acta cir. bras; 37 (1), 2022
Purpose: To investigate the role of peptidyl-prolyl cis/trans isomerase 1 (Pin1) on renal ischemia-reperfusion (I/R) injury and underlying mechanism. Methods: By establishing the in vitro and in vivo models of renal I/R, the role of Pin1 was explored by using molecular assays. Results: In renal I/R, en...

LncRNA MALAT1 aggravates oxygen-glucose deprivation/reoxygenation-induced neuronal endoplasmic reticulum stress and apoptosis via the miR-195a-5p/HMGA1 axis

Biol. Res; 54 (), 2021
BACKGROUND: This study aimed to investigate the potential role and molecular mechanism of lncRNA metastasis associated lung adenocarcinoma transcript 1 (MALAT1) in cerebral ischemia/reperfusion injury. RESULTS: Using an oxygen-glucose deprivation/reoxygenation (OGD/R) cell model, we determined that the e...

La respuesta a proteínas mal plegadas como blanco terapéutico en la enfermedad de Alzheimer

Rev. méd. Chile; 148 (2), 2020
The clinical features of Alzheimer's disease (AD), for example the progressive memory loss, are produced by neuronal loss and synaptic dysfunction. These events have been associated with histopathological alterations in AD brain, including the presence of amyloid plaques and neurofibrillary tangles. Rece...

Glutamine protects intestine against ischemia-reperfusion injury by alleviating endoplasmic reticulum stress induced apoptosis in rats

Acta cir. bras; 35 (1), 2020
Abstract Purpose Glutamine, as an essential part of enteral nutrition and parenteral nutrition agent, has been widely recognized to be a kind of important intestinal mucosa protectant in clinical practice and experimental research. However, the mechanisms of its protective effects are still not fully u...

Psoralen inhibits malignant proliferation and induces apoptosis through triggering endoplasmic reticulum stress in human SMMC7721 hepatoma cells

Biol. Res; 52 (), 2019
BACKGROUND: Psoralen is a coumarin-like and coumarin-related benzofuran glycoside, which is a commonly used traditional Chinese medicine to treat patients with kidney and spleen-yang deficiency symptom. Psoralen has been reported to show estrogen-like activity, antioxidant activity, osteoblastic prolifer...

α-Linolenic acid prevents hepatic steatosis and improves glucose tolerance in mice fed a high-fat diet

Clinics; 73 (), 2018
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 un...

Adiponectin is protective against endoplasmic reticulum stress-induced apoptosis of endothelial cells in sepsis

Braz. j. med. biol. res; 51 (12), 2018
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...
