科学家揭示急性运动后分子层面的全身改变

美国斯坦福大学医学院Michael P. Snyder、Francois Haddad等研究人员合作报道了急性运动后分子层面的全身改变。相关论文于2020年5月28日发表在《细胞》杂志上。

在36个志愿者运动前后,研究人员对血浆和外周血单个核细胞(包括代谢组、脂质组、免疫组、蛋白质组和转录组)进行了纵向多组学分析。时间序列分析揭示了成千上万的分子变化和生物过程的精心编排,涉及能量代谢、氧化应激、炎症、组织修复和生长因子反应以及调节途径。
 
在胰岛素抵抗的参与者中,大多数的这些过程被抑制,而某些过程则被逆转。最后,研究人员发现了参与心肺运动反应的生物途径,并建立了预测模型,从而揭示了静息血液峰值耗氧量的潜在生物标志物。
 
据了解,急性体育锻炼会导致代谢、心血管和免疫途径的若干变化。尽管以前的研究已经报道了这些途径中的某些变化,但是对急性运动的全系统分子反应尚未得到充分表征。

Abstract: Acute physical activity leads to several changes in metabolic, cardiovascular, andimmune pathways. Although studies have examined selected changes in these pathways,the system-wide molecular response to an acute bout of exercise has not been fullycharacterized. We performed longitudinal multi-omic profiling of plasma and peripheralblood mononuclear cells including metabolome, lipidome, immunome, proteome, and transcriptomefrom 36 well-characterized volunteers, before and after a controlled bout of symptom-limitedexercise. Time-series analysis revealed thousands of molecular changes and an orchestratedchoreography of biological processes involving energy metabolism, oxidative stress,inflammation, tissue repair, and growth factor response, as well as regulatory pathways.Most of these processes were dampened and some were reversed in insulin-resistantparticipants. Finally, we discovered biological pathways involved in cardiopulmonaryexercise response and developed prediction models revealing potential resting blood-basedbiomarkers of peak oxygen consumption.
