概括
在长时间的清醒和咖啡因摄入期间,COMT rs4680基因型会影响胰岛素类生长因子1 (IGF-1) 水平. 咖啡因会影响IGF-1的动力学和恢复,但不会影响或皮质醇的反应,不管是COMT或ADORA2A基因变异.
科学领域:
- 神经科学是一个神经科学.
- 遗传学 是一个遗传学.
- 内分泌学 在内分泌学.
背景情况:
- 像COMT和ADORA2A这样的基因会影响认知功能和咖啡因反应.
- COMT rs4680的多态性与记忆和IGF-1水平有关.
- 了解在压力期间对神经营养因子的遗传影响至关重要.
研究的目的:
- 为了研究长时间清醒期间IGF-1,和皮质醇的动力学.
- 为了检查咖啡因与安慰剂对这些激素的影响.
- 要确定这些反应是否被COMT rs4680和ADORA2A rs5751876多态度调节.
主要方法:
- 37名健康参与者经历了长时间的清醒,并接受了可控的咖啡因或安慰剂摄入.
- 血液样本在37小时的多个时间点收集,并在恢复睡眠后收集.
- 分析了荷尔蒙度 (IGF-1,,皮质醇) 和遗传多态性 (COMT,ADORA2A).
主要成果:
- 在安慰剂组中,IGF-1水平在清醒期间增加,特别是在COMT A/A基因型的个体中.
- 咖啡因降低了IGF-1反应和康复后的休息水平,以COMT基因型依赖的方式.
- 在清醒状态下下降,咖啡因减轻了这种影响,独立于COMT/ADORA2ASNP;皮质醇也下降了,不受咖啡因或基因型的影响.
结论:
- COMT rs4680的多态性在调节IGF-1对睡眠剥夺和咖啡因反应方面发挥着重要作用.
- 咖啡因对IGF-1动态的影响受COMT基因型的影响.
- 没有观察到ADORA2ASNP对所研究的荷尔蒙反应有显著影响.

Insufficient Sleep and Sleep Deprivation
186
Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.

Substance Use Disorders Affecting Sleep
199
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.

Management of Insomnia
284
The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...

Sedatives and Hypnotics Drugs: Miscellaneous Agents
205
Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...

Insomnia
111
Insomnia is a prevalent sleep disorder characterized by difficulty falling asleep, frequent awakenings during the night, and waking up too early without being able to return to sleep. People with insomnia often experience these disruptions at least three nights a week for at least one month. Chronic insomnia, which lasts for at least three months, can lead to increased anxiety, which in turn can worsen sleep difficulties, creating a cycle of sleeplessness and stress.

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...
