Iron overload reduces adiponectin receptor expression via a ROS/FOXO1?dependent mechanism leading to adiponectin resistance in skeletal muscle cells

چکیده
Iron overload (IO) is a common yet underappreciated finding in metabolic syndrome (MetS) patients. With the prevalence of MetS continuing to rise, it imperative further elucidate cellular mechanisms leading dysfunction. Adiponectin has many beneficial effects and therapeutic target for treatment cardiovascular diseases. IO positively correlates with reduced circulating adiponectin levels impact on action unknown. Here, we established model L6 skeletal muscle cells found that IO-induced resistance. This was shown via p38 mitogen-activated protein kinase phosphorylation response small molecule receptor (AdipoR) agonist, AdipoRon, presence IO. correlated messenger RNA AdipoR1 its facilitative signaling binding partner, APPL1. caused phosphorylation, nuclear extrusion, thus inhibition FOXO1, known transcription factor regulating expression. The antioxidant N-acetyl cystine attenuated production reactive oxygen species (ROS) by IO, blunted effect FOXO1 removal from nucleus, as well subsequent In conclusion, our study identifies ROS/FOXO1/AdipoR1 axis cause resistance new knowledge provides insight into mechanism potential relevance disease pathophysiology patients

Enhanced adiponectin multimer ratio and skeletal muscle adiponectin receptor expression following exercise training and diet in older insulin-resistant adults.
Circulating adiponectin is reduced in disorders associated with insulin resistance. This study was conducted to determine whether an exercise/diet intervention would alter adiponectin multimer distribution and adiponectin receptor expression in skeletal muscle. Impaired glucose-tolerant older (>60 yr) obese (BMI 30-40 kg/m(2)) men (n = 7) and women (n = 14) were randomly assigned to 12 wk of su...

OBJECTIVE It has been suggested that adiponectin regulates plasma free fatty acid (FFA) clearance by stimulating FFA uptake and/or oxidation in muscle. We aimed to determine changes in plasma adiponectin concentration and adiponectin receptor 1 and 2 mRNA expression in skeletal muscle during and after prolonged exercise under normal, fasting conditions (high FFA trial; HFA) and following pharma...

OBJECTIVE Adiponectin is an adipocyte-derived protein that acts to reduce insulin resistance in the liver and muscle and also inhibits atherosclerosis. Although adiponectin reportedly enhances AMP-activated protein kinase and inhibits tumor necrosis factor-alpha action downstream from the adiponectin signal, the precise physiological mechanisms by which adiponectin acts on skeletal muscles rema...

Background: Endometriosis is a complex disorder in reproductive age women which consist of stromal and epithelial cells implantation outside the uterine cavity. Adiponectin is a member of cytokine family with various metabolic roles and proliferation inhibition of many cancer cells. The aim of the present research was to determine adiponectin effect on human endometriotic stromal cells (ESCs) p...
