概括

新型抗糖尿病药物伊梅格林 (imeglimin) 显著影响小鼠细胞中的昼夜时钟,与甲福明不同. 这表明伊梅格林可能会影响生物节奏,这需要进一步的体内研究.

科学领域:

时间生物学时间生物学
药理学药理学是指药理学的学科.
分子生物学分子生物学

背景情况:

伊梅格林是一种新型抗糖尿病药物,其结构与甲福明相似.
在之前的研究中,甲胺已经证明对调节昼夜时钟的影响.
昼夜时钟在调节生理过程中起着至关重要的作用.

研究的目的:

调查伊梅格林对小鼠胚胎纤维细胞 (MEFs) 昼夜振荡器的影响.
为了比较伊梅格林与甲胺对昼夜节律的作用.

主要方法:

具有Bmal1-Emerald luciferase记者的MEFs被用imeglimin,metformin,FK866或载体进行治疗.
对Bmal1-Emerald luciferase表达节奏进行了55小时的监测.
时钟基因mRNA表达水平在32小时内被分析.

主要成果:

伊梅格林显著延长了Bmal1-Emerald luciferase表达节奏的时间和幅度.
甲胺对这些昼夜参数的影响很小.
伊梅格林影响了关键时钟基因 (Bmal1,Per1,Cry1) 的节奏表达,这种效应被FK866.6部分抑制.

Circadian Rhythms and Gene Regulation

Circadian Rhythms and Gene Regulation

The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...
