心理药物可以引起代谢副作用. 这项研究发现了表观遗传变化,特别是DNA甲基化变化,与这些药物治疗的患者的体重增加有关,为治疗机制提供了新的见解.
科学领域:
- 表观遗传学 在表观遗传学中,表观遗传学是指表观遗传学.
- 心理药理学 心理药理学
- 代谢健康 代谢健康
背景情况:
- 心理药物的代谢副作用阻碍了成功的患者治疗.
- 表观遗传修饰,特别是DNA甲基化,越来越被认为是生物过程中至关重要的.
- 了解这些变化对于管理与治疗有关的不良影响至关重要.
研究的目的:
- 为了研究与精神药物治疗相关的DNA甲基化变化.
- 评估早期代谢变化 (体重增加) 和DNA甲基化之间的关系.
- 探索潜在的表观遗传机制背后的心理药物诱导的体重增加.
主要方法:

- 纵向研究设计,在基线和治疗1个月后进行测量.
- 对79名开始服用诱导体重增加的精神药物的患者进行分析.
主要成果:
- 在治疗1个月后,观察到DNA甲基化总体增加.
- 在整个队列中,在52个位点发现了显著的甲基化变化.
- 一个特定的位点 (cg12209987) 显示甲基化增加与显著的体重增加相关.
- 门德尔的随机化表明了基线甲基化 (cg11622362) 对血糖的潜在因果作用.
结论:
- 心理药物治疗会诱导显著的表观遗传变化,包括DNA甲基化变化.
- 这些表观遗传修饰可能在调解药物诱导的体重增加中发挥作用.

Phase II Reactions: Methylation Reactions
The mechanism of methylation unfolds in two stages. The first stage sees a methyltransferase enzyme facilitating the transfer of a methyl group from S-adenosylmethionine (SAM) to the substrate, forming S-adenosylhomocysteine (SAH). The second stage involves further metabolism of SAH into homocysteine, which can be recycled...
