Circadian Rhythms and Gene Regulation

4.1K
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...

  • 循环节律是指循环节律的节奏.
  • 行为神经科学 行为神经科学

背景情况:

  • 食物引诱振荡器 (FEO) 控制食物预测活动 (FAA),但其位置和机制仍然难以捉摸.
  • 由于技术限制,将FAA与其他昼夜节律区分开来是具有挑战性的.

研究的目的:

  • 调查FEO的位置和属性.
  • 了解食物预期背后的分子机制.

主要方法:

  • 使用养实验装置版本3 (FED3) 来监测小鼠的鼻行为.
  • 操纵的食物可用性时间表和光暗周期.
  • 研究期间1/2/3三重淘汰赛小鼠缺乏功能性上神核 (SCN).

主要成果:

  • 鼠标表现出预期的鼻行为,即使没有食物可用.
  • 预期性行为随着光暗周期的转变而变化,独立于餐点的时间.
  • 在具有非功能性SCN的小鼠中,食物预测活性持续存在.

结论:

  • 预期食物是由一个新的,外SCN光可引振振荡器控制的.
  • 这种振荡器与SCN中的主要昼夜节律起器不同.
  • 这些发现挑战了现有的昼夜计时模型.
