细胞核的大小和形状受到严格的调控,表明适当的细胞核形态的生理意义,但细胞核大小和形状调控的机制和功能仍然知之甚少。改变的细胞核形态和某些疾病状态之间的相关性早已被观察到,最值得注意的是,许多癌症的诊断和分期是基于细胞核大小的分级增加。在这里,我们回顾了最近的研究调查的机制,调节核的大小和形状,有丝分裂事件如何影响核形态,核的大小和形状在亚核染色质组织和癌症进展的作用。
The size and shape of the nucleus are tightly regulated, indicating the physiological significance of proper nuclear morphology, yet the mechanisms and functions of nuclear size and shape regulation remain poorly understood. Correlations between altered nuclear morphology and certain disease states have long been observed, most notably many cancers are diagnosed and staged based on graded increases in nuclear size. Here we review recent studies investigating the mechanisms regulating nuclear size and shape, how mitotic events influence nuclear morphology, and the role of nuclear size and shape in subnuclear chromatin organization and cancer progression.
