背景:骨质疏松被认为是一种以骨组织质量和密度降低为特征的骨骼疾病。定期体育锻炼被广泛认为可以保持和增强骨骼健康,但详细的分子机制仍不清楚。Irisin,运动过程中肌肉产生的一个因素,影响骨骼和肌肉。自2012年发现以来,irisin已被发现可促进骨骼生长并减少骨骼吸收,在肌肉锻炼和骨骼健康之间建立切实的联系。因此,irisin预防骨质疏松症的机制引起了极大的科学兴趣。
目的:本研究旨在阐明运动之间的多方面关系,irisin,骨骼健康。专注于艾瑞辛,运动过程中释放的肌肉衍生因子,我们试图了解它在促进骨骼生长和抑制吸收中的作用。通过综述目前关于irisin在骨质疏松症中的研究文章,我们的综述提供了对现有的研究的影响irisin骨质疏松症,探索其与关键信号通路的相互作用及其对各种细胞死亡机制和炎症的影响。我们的目标是揭示艾瑞辛的分子基础,在运动过程中分泌,可以作为骨质疏松症的治疗策略。
■Irisin,在运动过程中分泌,在桥接肌肉功能与骨骼健康中起着至关重要的作用。它不仅促进骨生长,而且抑制骨吸收。具体来说,Irisin促进成骨细胞增殖,分化,矿化主要通过ERK,p38和AMPK信号通路。同时,它通过JNK调节破骨细胞的分化和成熟,Wnt/β-catenin和RANKL/RANK/OPG信号通路。这篇综述进一步探讨了irisin在骨质疏松症及其参与多种细胞死亡机制中的深远意义。包括细胞凋亡,自噬,铁性凋亡,和焦亡。
BACKGROUND: Osteoporosis is recognized as a skeletal disorder characterized by diminished bone tissue quality and density. Regular physical exercise is widely acknowledged to preserve and enhance bone health, but the detailed molecular mechanisms involved remain unclear.
Irisin, a factor derived from muscle during exercise, influences bone and muscle. Since its discovery in 2012,
irisin has been found to promote bone growth and reduce bone resorption, establishing a tangible link between muscle exertion and bone health. Consequently, the mechanism by which irisin prevents osteoporosis have attracted significant scientific interest.
OBJECTIVE: This study aims to elucidate the multifaceted relationship between exercise, irisin, and bone health. Focusing on
irisin, a muscle-derived factor released during exercise, we seek to understand its role in promoting bone growth and inhibiting resorption. Through a
review of current research article on
irisin in osteoporosis, Our
review provides a deep dive into existing research on influence of irisin in osteoporosis, exploring its interaction with pivotal signaling pathways and its impact on various cell death mechanisms and inflammation. We aim to uncover the molecular underpinnings of how irisin, secreted during exercise, can serve as a therapeutic strategy for osteoporosis.
UNASSIGNED: Irisin, secreted during exercise, plays a vital role in bridging muscle function to bone health. It not only promotes bone growth but also inhibits bone resorption. Specifically, Irisin fosters osteoblast proliferation, differentiation, and mineralization predominantly through the ERK, p38, and AMPK signaling pathways. Concurrently, it regulates osteoclast differentiation and maturation via the JNK, Wnt/β-catenin and RANKL/RANK/OPG signaling pathways. This
review further delves into the profound significance of
irisin in osteoporosis and its involvement in diverse cellular death mechanisms, including apoptosis, autophagy, ferroptosis, and pyroptosis.
