The syncytial Drosophila embryo as a mechanically excitable medium [PDF]
Mitosis in the early syncytial Drosophila embryo is highly correlated in space and time, as manifested in mitotic wavefronts that propagate across the embryo. In this paper we investigate the idea that the embryo can be considered a mechanically-excitable medium, and that mitotic wavefronts can be understood as nonlinear wavefronts that propagate ...

Kinesins relocalize the chromosomal passenger complex to the midzone for spindle disassembly. [PDF]
Mitotic spindle disassembly after chromosome separation is as important as spindle assembly, yet the molecular mechanisms for spindle disassembly are unclear.

A Wee1 checkpoint inhibits anaphase onset [PDF]
Cdk1 drives both mitotic entry and the metaphase-to-anaphase transition. Past work has shown that Wee1 inhibition of Cdk1 blocks mitotic entry. Here we show that the budding yeast Wee1 kinase, Swe1, also restrains the metaphase-to-anaphase transition by preventing Cdk1 phosphorylation and activation of the mitotic form of the anaphase-promoting complex/

Nur1 dephosphorylation confers positive feedback to mitotic exit phosphatase activation in budding yeast. [PDF]
Substrate dephosphorylation by the cyclin-dependent kinase (Cdk)-opposing phosphatase, Cdc14, is vital for many events during budding yeast mitotic exit.

Cell cycle: Oiling the gears of anaphase [PDF]
The anaphase-promoting complex (APC) or cyclosome directs the ubiquitination and destruction of proteins that control specific steps in mitosis. Recent studies show that APC activity requires WD40 domain proteins, and that one of these proteins is part of the checkpoint control that ensures accurate chromosome segregation.

Dual targeting of AKT and mTOR using MK2206 and RAD001 reduces tumor burden in an intracardiac colon cancer circulating tumor cell xenotransplantation model. Analysis of AKT isoform‐specific knockdowns in CTC‐MCC‐41 reveals differentially regulated proteins and phospho‐proteins by liquid chromatography coupled mass spectrometry. Circulating tumor cells

Mitotic Exit Function of Polo-like Kinase Cdc5 Is Dependent on Sequential Activation by Cdk1
To complete mitosis, Saccharomyces cerevisiae needs to activate the mitotic phosphatase Cdc14. Two pathways contribute to Cdc14 regulation: FEAR (Cdc14 early anaphase release) and MEN (mitotic exit network).

Bub1 is a fission yeast kinetochore scaffold protein, and is sufficient to recruit other spindle checkpoint proteins to ectopic sites on chromosomes. [PDF]
The spindle checkpoint delays anaphase onset until all chromosomes have attached in a bi-polar manner to the mitotic spindle. Mad and Bub proteins are recruited to unattached kinetochores, and generate diffusible anaphase inhibitors.

Contrasting roles of condensin I and condensin II in mitotic chromosome formation [PDF]
© 2012. Published by The Company of Biologists LtdIn vertebrates, two condensin complexes exist, condensin I and condensin II, which have differing but unresolved roles in organizing mitotic chromosomes.

Spatial control of the anaphase-telophase transition [PDF]
The ultimate goal of mitosis is to physically separate the entire set of duplicated chromosomes in order to propagate the genetic information during cell division. The perpetuation of a faithful maintenance of the genome integrity can only be guaranteed by the existence of multiple cell cycle checkpoints.1 In particular, mitosis is a highly regulated ...
