急性炼通过N6-甲基氨酸 (m6A) 修饰诱导白色脂肪组织 (WAT) 变色,由代谢物β-基酸盐 (BHBA) 驱动. BHBA增强了热生成并改善了代谢平衡,提供了一个新的治疗点.
科学领域:
- 代谢适应的过程
- 表观遗传学 在表观遗传学中,表观遗传学是指表观遗传学.
- 脂肪组织生物学 脂肪组织生物学
背景情况:
- 定期炼有助于白色脂肪组织 (WAT) 和代谢适应.
- 急性运动的影响和N6-甲基氨酸 (m6A) 在这些适应中的作用尚未完全理解.
研究的目的:
- 为了研究一次性急性运动对WAT代谢和运动的影响.
- 阐明m6A修饰在运动诱导的WAT适应中的作用.
主要方法:
- 慢性和急性运动的小鼠模型.
- 代谢表型化和转录组测序的WAT.
- 在急性运动后的WAT中探索m6A修饰和目标基因.
主要成果:
- 急性炼可提高WAT中的m6A修饰的调节,诱导糖溶性色脂肪 (g-色脂肪) 的形成.
- 运动后分泌的代谢物beta-hydroxybutyrate (BHBA) 升高调节了WAT m6A的修饰.
- BHBA增强了CREBBP的m6A依赖翻译,增加了染色质的可访问性,并促进了beiging基因转录.
- 药理上升的BHBA模仿运动效应,并改善肥胖的代谢平衡.
结论:
- 代谢物在急性运动后通过m6A介导的染色质可访问性对WAT代谢适应起着至关重要的作用.
- 这项研究从营养表观遗传学的角度确定了调节WAT代谢的新疗法标.

Chromatin Modification in iPS Cells
Compact chromatin makes reprogramming difficult. Enzymes, such as histone demethylases and acetyltransferases, are often added during reprogramming to loosen the chromatin, making the DNA more accessible to transcription factors. Molecules that inhibit histone...
