Most of the processes that occur in the mind and body follow natural rhythms. Those with a cycle length of about one day are called circadian rhythms. These rhythms are driven by a system of self-sustained clocks and are entrained by environmental cues such as light-dark cycles as well as food intake. In mammals, the circadian clock system is hierarchically organized such that the master clock in the suprachiasmatic nuclei of the hypothalamus integrates environmental information and synchronizes the phase of oscillators in peripheral tissues.The circadian system is responsible for regulating a variety of physiological and behavioral processes, including feeding behavior and energy metabolism. Studies revealed that the circadian clock system consists primarily of a set of clock genes. Several genes control the biological clock, including BMAL1, CLOCK (positive regulators), CRY1, CRY2, PER1, PER2, and PER3 (negative regulators) as indicators of the peripheral clock.Circadian has increasingly become an important area of medical research, with hundreds of studies pointing to the body's internal clocks as a factor in both health and disease. Thousands of biochemical processes from sleep and wakefulness to DNA repair are scheduled and dictated by these internal clocks. Cancer is an example of health problems where chronotherapy can be used to improve outcomes and deliver a higher quality of care to patients.In this article, we will discuss knowledge about molecular mechanisms of the circadian clock and the role of clocks in physiology and pathophysiology of concerns.

探索昼夜节律时钟基因的作用及其与癌症病理生理学的关系。

发生在身心中的大多数过程都遵循自然的节奏。那些周期长度约为一天的昼夜节律。这些节律由一套自持的时钟系统驱动,并受到诸如光暗循环和食物摄入等环境提示的夹带。在哺乳动物中,昼夜节律系统是按层次结构组织的,因此下丘脑上眼睑上核中的主钟整合了环境信息并同步了周围组织中振荡器的相位。昼夜节律系统负责调节各种生理和行为过程,包括进食行为和能量代谢。研究表明,生物钟系统主要由一组时钟基因组成。几种基因控制着生物钟,包括BMAL1,时钟(正调节器),CRY1,CRY2,PER1,PER2和PER3(负调节器)作为外围时钟的指示器。昼夜节律已日益成为医学研究的重要领域,数百项研究都将人体内部时钟视为既影响健康又影响疾病。这些内部时钟安排并指示了从睡眠,清醒到DNA修复的成千上万个生化过程。癌症是健康问题的一个例子,可以使用计时疗法改善结果并为患者提供更高质量的护理。在本文中,我们将讨论有关生物钟的分子机制知识以及生物钟在生理和病理生理中的作用。关注。昼夜节律已日益成为医学研究的重要领域,数百项研究指出人体的内部时钟是健康和疾病的一个因素。这些内部时钟安排并指示了从睡眠,清醒到DNA修复的成千上万个生化过程。癌症是健康问题的一个例子,可以使用计时疗法改善结果并为患者提供更高质量的护理。在本文中,我们将讨论有关生物钟的分子机制知识以及生物钟在生理和病理生理中的作用。关注。昼夜节律已日益成为医学研究的重要领域,数百项研究指出人体的内部时钟是健康和疾病的一个因素。这些内部时钟安排并指示了从睡眠和清醒到DNA修复的成千上万个生化过程。癌症是健康问题的一个例子,可以使用计时疗法改善结果并为患者提供更高质量的护理。在本文中,我们将讨论有关生物钟的分子机制知识以及生物钟在生理和病理生理中的作用。关注。这些内部时钟安排并指示了从睡眠,清醒到DNA修复的成千上万个生化过程。癌症是健康问题的一个例子,可以使用计时疗法改善结果并为患者提供更高质量的护理。在本文中,我们将讨论有关生物钟的分子机制知识以及生物钟在生理和病理生理中的作用。关注。这些内部时钟安排并指示了从睡眠和清醒到DNA修复的成千上万个生化过程。癌症是健康问题的一个例子,可以使用计时疗法改善结果并为患者提供更高质量的护理。在本文中,我们将讨论有关生物钟的分子机制知识以及生物钟在生理和病理生理中的作用。关注。
