Summary
Cytokinetic abscission ensures cell division by cleaving the intercellular bridge. This review details factors regulating this process and its link to tumor formation, proposing new cancer therapy strategies.
Area of Science:
- Cell Biology
- Molecular Biology
- Genetics
Background:
- Cytokinetic abscission is essential for cell division, involving the separation of daughter cells via intercellular bridge cleavage.
- Proper regulation of the cytoskeleton is critical for successful cell separation.
Purpose of the Study:
- To review key scientific discoveries in the activation of the abscission checkpoint.
- To explore factors regulating the timing and execution of cytokinetic abscission.
- To discuss the implications of abscission dysregulation in human diseases, particularly cancer.
Main Methods:
- Literature review of scientific discoveries related to cell division and abscission.
- Analysis of factors influencing the abscission checkpoint, including ICB tension, nuclear pore defects, and DNA replication stress.
- Exploration of the role of midbody proteins in regulating abscission.
Main Results:
- Identified critical factors for abscission checkpoint activation and successful cell separation.
- Detailed the regulatory mechanisms involving cellular contributors and intracellular processes.
- Highlighted the link between abscission dysregulation and tumor formation.
Conclusions:
- Abscission checkpoint activation is crucial for accurate cell division.
- Dysregulation of cytokinetic abscission can lead to cellular defects and cancer.
- Further research into abscission mechanisms may yield novel cancer therapies.

02:19The Spindle Assembly Checkpoint
3.1K
The spindle assembly checkpoint is a molecular surveillance mechanism ensuring the fidelity of chromosome segregation during anaphase. The checkpoint monitors the completion of all the prerequisite steps before chromosome segregation to determine whether the segregation process should proceed or be delayed.
Many proteins function together to control the spindle assembly checkpoint. Mutations affecting these proteins may allow cells to proceed into anaphase prematurely, resulting in the...

02:17Separation of Sister Chromatids
3.6K
At the transition from prophase to metaphase, there is a reduction in cohesion along the chromosomal arms, resulting in the resolution of sister chromatids. However, residual cohesin connections remain to hold the sister chromatids together until the transition from metaphase to anaphase. The residual connection prevents any premature separation of sister chromatids, blocking the risks of aneuploidy within the daughter cells.

02:15The Contractile Ring
6.3K
Contractile rings are composed of microfilaments and are responsible for separating the daughter cells during cytokinesis. Contractile ring assembly proceeds along with other cell cycle events; however, very few mechanistic details are known about the timing and coordination of the contractile rings with the cell cycle.
A small GTPase, RhoA, controls the function and assembly of the contractile ring. RhoA belongs to the Ras superfamily of proteins. The activation of formins by RhoA promotes...

01:28The Cell Cycle Control System
2.7K
The cell cycle regulation directs how a cell proceeds from one phase to the next and begins mitosis. The cell cycle control system includes intracellular regulatory molecules and external triggers. They provide "stop" or "advance" signals and operate at specific cell cycle stages termed checkpoints to ensure that a particular process is completed before the cell advances to the next phase.

00:50Anaphase Promoting Complex
2.8K
The stepwise destruction of specific proteins is necessary for the progression and completion of the cell cycle. Such proteins are ubiquitinated by ubiquitin ligases and then subsequently destroyed by the proteasome. The SCF (Skp1/Cullin/F-box) and the anaphase-promoting complex (APC) are two important ubiquitin ligases involved in cell cycle progression. While SCF is active throughout the cell cycle, APC gets activated during metaphase to anaphase transition. Cdc20 or Cdh1 binds to APC and...

01:27Molecular Factors Affecting Cell Division
3.0K
Several external and internal factors influence the initiation and inhibition of cell division. For instance, the death of nearby cells or the release of human growth hormone (hGH) promotes cell division. In contrast, lack of hGH or crowding of cells can inhibit cell division.
Several proteins function as internal regulators to ensure each cell cycle stage is completed faithfully before proceeding to the next. Regulator molecules may act directly or influence the activity or production of other...
