首先,我们可以把一个细胞的周期分为间期interphase以及分裂期celldivision phase. 其中interphase是在做一些准备工作,而celldivision phase则是真正的在分裂 当然,事情并没有这么简单。 每一个phase接下来都可以更细节的分为几个阶段。 Interphase G0/G1phase -A resting phase -Cell perform own function -Some type...

In fact, most of the cells in interphase show a single crystal, originating close to the nucleus. This raises the possibility that the nucleation site of the crystal overlaps with the nucleation site of MTs. MTs nucleate mainly from MT organizing centers located close to the cell center. ...
Eukaryotic chromosomes undergo dramatic compaction and decompaction in the life cycle of a cell, and the dynamic chromosomal structure plays an integral role in a range of nuclear processes such as DNA replication, recombination, repair and gene transcription1,2,3,4,5. In interphase nuclei, differ...

The Cyclin-dependent kinase (CDK) class of serine/threonine kinases has crucial roles in the regulation of cell cycle transition and is mainly involved in the pathogenesis of cancers. The expression of CDKs is controlled by a complex regulatory network c
found in all major kingdoms of eukaryotes. This protein is required for the assembly and function of the meiotic or mitotic spindles during cell division and is localized to microtubule-organizing centers (MTOCs) during interphase or to the spindle poles and centrosomes during mitosis or ...

In addition to the structural roles of A-type lamins, Lamin A/C has been shown to play a role in the regulation of gene expression and cell cycle progression, and alterations in the LMNA gene is cause of human diseases called laminopathies. Dex was found to improve the nucleoplasmic ...
