Abstract

The intricate relationship between bile acid metabolism and skeletal muscle function has emerged as a crucial area of research in metabolic health. This review synthesizes current evidence highlighting the fundamental role of bile acids as key signaling molecules in muscle homeostasis and their therapeutic potential in muscle-related disorders. Recent advances in molecular biology and metabolomics have revealed that bile acids, beyond their classical role in lipid absorption, function as essential regulators of muscle mass and function through multiple signaling pathways, particularly via the nuclear receptor FXR and membrane receptor TGR5. Clinical studies have demonstrated significant associations between altered bile acid profiles and muscle wasting conditions, while experimental evidence has elucidated the underlying mechanisms linking bile acid signaling to muscle protein synthesis, energy metabolism, and regeneration capacity. We critically examine the emerging therapeutic strategies targeting bile acid pathways, including receptor-specific agonists, microbiome modulators, and personalized interventions based on individual bile acid profiles. Additionally, we discuss novel diagnostic approaches utilizing bile acid-based biomarkers and their potential in early detection and monitoring of muscle disorders. This review also addresses current challenges in standardization and clinical translation while highlighting promising future directions in this rapidly evolving field. Understanding the bile acid-muscle axis may provide new opportunities for developing targeted therapies for age-related muscle loss and metabolic diseases.

胆汁酸信号在骨骼肌稳态中的作用:从分子机制到临床应用。
胆汁酸代谢与骨骼肌功能之间的复杂关系已成为代谢健康研究的一个重要领域。这篇综述综合了目前的证据,强调了胆汁酸作为肌肉稳态的关键信号分子的基本作用及其在肌肉相关疾病中的治疗潜力。分子生物学和代谢组学的最新进展表明,胆汁酸除了在脂质吸收中的经典作用外,还可以通过多种信号通路,特别是通过核受体FXR和膜受体TGR5,作为肌肉质量和功能的重要调节剂。临床研究已经证明胆汁酸谱的改变与肌肉萎缩状况之间存在显著关联,而实验证据已经阐明了胆汁酸信号传导与肌肉蛋白质合成、能量代谢和再生能力之间的潜在机制。我们仔细研究了针对胆汁酸途径的新兴治疗策略,包括受体特异性激动剂、微生物组调节剂和基于个体胆汁酸谱的个性化干预。此外,我们还讨论了利用胆汁酸生物标志物的新型诊断方法及其在早期检测和监测肌肉疾病方面的潜力。这篇综述还讨论了目前在标准化和临床翻译方面的挑战,同时强调了这一快速发展领域的有希望的未来方向。了解胆汁酸-肌肉轴可能为开发针对年龄相关肌肉损失和代谢性疾病的靶向治疗提供新的机会。

期刊介绍: Frontiers in Endocrinology is a field journal of the "Frontiers in" journal series. In today’s world, endocrinology is becoming increasingly important as it underlies many of the challenges societies face - from obesity and diabetes to reproduction, population control and aging. Endocrinology covers a broad field from basic molecular and cellular communication through to clinical care and some of the most crucial public health issues. The journal, thus, welcomes outstanding contributions in any domain of endocrinology. Frontiers in Endocrinology publishes articles on the most outstanding discoveries across a wide research spectrum of Endocrinology. The mission of Frontiers in Endocrinology is to bring all relevant Endocrinology areas together on a single platform.
