FNDC5 (fibronectin domain-containing [protein] 5) was initially discovered and characterized by two groups in 2002. In 2011 FNDC5 burst into prominence as the parent of irisin, a small protein containing the fibronectin type III domain. Irisin was proposed to be secreted by skeletal muscle cells in response to exercise, and to circulate to fat tissue where it induced a transition to brown fat. ...
FNDC5/irisin, has recently been identified as a novel protein that stimulates the "browning" of white adipose by inducing thermogenesis via increased uncoupling protein 1 (UCP1). We tested the hypothesis that high fat diet-induced prediabetic mice would exhibit increased FNDC5 and this effect would be attenuated by chronic exercise. C57BL/6 mice were randomized into three groups for the 4 week ...
AIMS Recent studies have revealed the relationship between irisin and insulin signaling, while positive associations of muscle FNDC5 with insulin resistance is observed. However, the functional mechanism of irisin on muscle insulin resistance is still obscure. This study aims to investigate the effect of irisin on muscle insulin action. METHODS Diabetic mouse model was established by high fat...
هدف از پژوهش حاضر بررسی تاثیر 8 هفته تمرین مقاومتی بر میزان پروتئین آیریزین پلاسما و بیان ژن های fndc5 عضله نعلی وucp1 بافت چربی زیر جلدی شکمی موش های صحرایی نر بود. 16 سر موش صحرایی نژاد اسپراگ دولی(میانگین وزن 2/22±5/211 گرم و سن 8 هفتگی) به طور تصادفی به دو گروه 8تایی کنترل و تمرین مقاومتی تقسیم شدند. گروه تمرینی به مدت 8 هفته و هفته ای 3 جلسه روی نردبان های مخصوص به ارتفاع 2/1 متر با حمل یک...
Irisin was recently identified as a putative myokine that is induced by exercise. Studies suggest that it is produced by cleavage of the FNDC5 (fibronectin domain-containing protein 5) receptor; irisin corresponds to the extracellular receptor ectodomain. Data suggesting that irisin stimulates white-to-brown fat conversion have led to the hypothesis that it does so by binding an unknown recepto...
AIMS/HYPOTHESIS Recently, the novel myokine irisin was described to drive adipose tissue 'browning', to increase energy expenditure, and to improve obesity and insulin resistance in high fat-fed mice. Here, we assessed whether common single nucleotide polymorphisms (SNPs) in the FNDC5 locus, encoding the irisin precursor, contribute to human prediabetic phenotypes (overweight, glucose intoleran...
The discovery of irisin as an exercise-regulated myokine inducing browning of WAT has gained interest as a potential new strategy to combat obesity and its associated disorders, such as type 2 diabetes. However, there are inconsistencies regarding the relevance of irisin in humans. The regulation of FNDC5 mRNA expression by exercise and contraction could not be reproduced by a number of human s...
Exercise can improve cognitive function and the outcome of neurodegenerative diseases, like Alzheimer's disease. This effect has been linked to the increased expression of brain-derived neurotrophic factor (BDNF). However, the underlying molecular mechanisms driving the elevation of this neurotrophin remain unknown. Recently, we have reported a PGC-1α-FNDC5/irisin pathway, which is activated by...
Fibronectin type III domain-containing 5 (FNDC5) is a skeletal muscle membrane-bound precursor to the myokine irisin. Irisin is involved in stimulating adipose tissue to become more metabolically active in order to produce heat. The purpose of this study was to determine the effects of exercise in a hot (33 °C), cold (7 °C), and room temperature (RT, 20 °C) environment on the skeletal muscle ge...
