| 中文摘要: |
| 自然界中生物体的生命活动、生活习性都存在着一定的周期性变化。生物昼夜节律的产生是以内源性的生物钟系统为基础
的。生物钟不仅易受到外界环境的影响，而且可以通过调控一系列特定的下游基因的表达，影响生物体的生理生化过程。巨核细
胞是生成血小板的前体细胞，经过分化、增殖、成熟和裂解，最终生成血小板。血小板是一种没有细胞核的特殊细胞，在生理性止
血和器官修复上发挥着重要作用，同时参与血栓等多种疾病的发生。近几年借助现代分子生物学和细胞生物学手段，证实了哺乳
动物的巨核细胞和血小板的生成呈现明显的周期性的变化，利用生物钟基因缺失模型进一步发现了生物钟基因对巨核细胞和血
小板的影响。本文概述了生物节律对巨核细胞和血小板的影响，为进一步研究巨核细胞的发育和血小板生成机制提供了参考。 |
| 英文摘要: |
| The activity and habit of organisms in nature exhibit circadian rhythms. The circadian rhythms in physiology and
behavior are controlled by internal circadian clock. The circadian clock is composed of several genes by transcription/translation-based
feedback loop. The circadian clock is not only affected by external environment, but also can regulate several downstream genes
expression, thus affecting the organism's physiological and biochemical processes. Megakaryocytes are precursor cells of platelet, which
generate platelets after differentiation, proliferation, maturation and fragmentation. Platelets are anucleate cells which play essential roles
in hemostasis and organ repair, participate in thrombosis and various diseases. In recent years, megakarycoytes and platelet formation
show significant circadian changes, and clock gene can affect megakaryocytes and platelet formation using gene knock-out animal
models. This article reviews the recent progress in the influence of circadian clock on megakarycytes and platelet, and provides evidences
to further understand the megakaryocyte development and the mechanism of platelet formation. |
