Background Irisin is an exercise-linked myokine produced by cleavage of the membrane precursor fibronectin type III domain-containing protein 5 (FNDC5) in skeletal muscle, brain, and other tissues. Recently, irisin has been identified as a key molecule for exercise-induced neuroprotection mouse models Alzheimer’s disease (AD). However, role FNDC5/irisin AD pathology not yet comprehensively expl...

The myokine irisin is supposed to be cleaved from a transmembrane precursor, FNDC5 (fibronectin type III domain containing 5), and to mediate beneficial effects of exercise on human metabolism. However, evidence for irisin circulating in blood is largely based on commercial ELISA kits which are based on polyclonal antibodies (pAbs) not previously tested for cross-reacting serum proteins. We hav...

Background: Fibronectin type III domain-containing 5 proteins (Fndc5), an exercise hormone, formerly known as peroxisomal protein that was cloned in 2002. Transcript profile analysis of Fndc5 revealed high degree of expression in heart, skeletal muscle and brain. Our recent studies indicated a significant increase (approximately 10 folds) in mRNA level of Fndc5 when mouse embryonic stem cells w...

BACKGROUND To investigate the impact of common variants of FNDC5 on type 2 diabetes and clinical traits related to glucose metabolism in a large Chinese population sample. METHODS Three tagging single nucleotide polymorphisms within the region of the FNDC5 gene were selected and genotyped in 6822 participants. Detailed clinical investigations and biochemistry measurements were carried out in ...

Obesity and obesity-related diseases including insulin resistance metabolic syndrome (MetS) pose a great risk for cardiovascular development. Skeletal muscle as an endocrine organ has pivotal role on secreting physiological factors such hormones myokines. Irisin that is one of these miyokines also known hormone secreted mainly from tissue in response to exercise. It dependent fibronectin type I...

Background. The accumulation of excess triglyceride in the liver and a decrease in brown adipose tissue is related to the fatty liver disease. Regular physical activity can take part in regulating fat oxidation and inhibiting fat accumulation by creating and releasing some myokines. Nevertheless, the effectiveness of each training method in this regard is still not certain. Objective(s). This ...

Background. Irisin is the result of the proteolysis of fibronectin type III domain-containing protein 5, the levels of which are determined by physical activity. Objective(s). This study aims to identify changes in FNDC5 gene expression and the heart muscle irisin levels in male rats following 8 weeks resistance and endurance training. Methods. Fifteen male rats (10-12 weeks old and 331.8&plu...
