Abstract

Obesity is a multifactorial metabolic disorder characterized by excessive fat accumulation and associated with numerous health risks, including insulin resistance, cardiovascular disease, and metabolic syndrome. Adipose tissue, particularly subcutaneous (SAT) and visceral (VAT) fat, plays a central role in metabolic regulation, yet its biochemical properties and functions differ significantly. While metabolomics offers a promising approach to studying adipose tissue at a molecular level, significant methodological limitations and inconsistencies in study design undermine the reliability of current findings. Although VAT is frequently characterized by a pro-inflammatory and lipolytic metabolic profile, whereas SAT is more involved in lipid storage and insulin, these generalizations overlook important depot-specific variations and fail to address the heterogeneity within adipose tissue. This critical review evaluates existing metabolomic studies, identifying key discrepancies in lipid metabolism, energy homeostasis, and inflammation-related pathways across VAT and SAT. It highlights the need for improved standardization in metabolomic analyses, greater inclusion of diverse populations, and more robust longitudinal studies. By addressing these issues, future research can provide more precise insights into adipose tissue's role in obesity-related metabolic dysfunction and better inform clinical strategies for obesity management.

从肥胖患者收集的腹部脂肪组织样本的代谢组学——一项重要的综述。
肥胖是一种多因素代谢紊乱,其特征是脂肪过度积累,并与多种健康风险相关,包括胰岛素抵抗、心血管疾病和代谢综合征。脂肪组织,特别是皮下脂肪(SAT)和内脏脂肪(VAT),在代谢调节中起着核心作用,但其生化特性和功能差异很大。虽然代谢组学为在分子水平上研究脂肪组织提供了一种很有前途的方法,但显著的方法局限性和研究设计的不一致性破坏了当前研究结果的可靠性。尽管VAT通常以促炎和脂溶代谢特征为特征,而SAT则更多地涉及脂质储存和胰岛素,但这些概括忽略了重要的储存特异性变化,未能解决脂肪组织内的异质性。这篇重要的综述评估了现有的代谢组学研究,确定了VAT和SAT在脂质代谢、能量稳态和炎症相关途径方面的关键差异。它强调了代谢组学分析需要改进标准化,更多地包括不同的人群,以及更有力的纵向研究。通过解决这些问题,未来的研究可以更准确地了解脂肪组织在肥胖相关代谢功能障碍中的作用,并更好地为肥胖管理的临床策略提供信息。
