严重的情绪障碍与昼夜节律的异常有关,导致睡眠,情绪,体温和激素水平的紊乱。我们提供的证据表明,氯胺酮,一种具有快速抗抑郁作用的药物,影响昼夜分子机制的功能。当这些调节因子在NG 108 -15神经元细胞中异位表达时,氯胺酮调节CLOCK:BMAL 1介导的转录激活。抑制以剂量依赖性方式发生,并在用GSK 3 β拮抗剂SB 21673处理后减弱。我们分析了氯胺酮对昼夜节律基因表达的影响,并观察到Bmal 1,Per 2和Cry 1基因的昼夜节律转录幅度呈剂量依赖性降低。最后,染色质免疫沉淀分析表明,氯胺酮改变了招聘的时钟:BMAL 1复合物的昼夜节律启动子在时间依赖性的方式。我们的研究结果揭示了一个尚未怀疑的氯胺酮的分子作用模式,从而可能建议可能的药理学抗抑郁策略。
Major mood disorders have been linked to abnormalities in circadian rhythms, leading to disturbances in sleep, mood, temperature, and hormonal levels. We provide evidence that ketamine, a drug with rapid antidepressant effects, influences the function of the circadian molecular machinery. Ketamine modulates CLOCK:BMAL1-mediated transcriptional activation when these regulators are ectopically expressed in NG108-15 neuronal cells. Inhibition occurs in a dose-dependent manner and is attenuated after treatment with the GSK3β antagonist SB21673. We analyzed the effect of ketamine on circadian gene expression and observed a dose-dependent reduction in the amplitude of circadian transcription of the Bmal1, Per2, and Cry1 genes. Finally, chromatin-immunoprecipitation analyses revealed that ketamine altered the recruitment of the CLOCK:BMAL1 complex on circadian promoters in a time-dependent manner. Our results reveal a yet unsuspected molecular mode of action of ketamine and thereby may suggest possible pharmacological antidepressant strategies.
