Cell Death and Differentiation
|June 2, 2012
Summary
Cancer cells often have extra centrosomes, which help them divide. Disrupting this centrosome clustering could lead to new cancer treatments that target cancer cells specifically.
Area of Science:
- Cell Biology
- Cancer Research
- Oncology
Background:
- Centrosomes, initially discovered a century ago, are implicated in chromosomal aberrations in cancer cells.
- Historically neglected in cancer research, centrosomes are now recognized as key players in tumorigenesis.
- Most cancer cells exhibit amplified centrosome numbers, unlike normal cells.
Purpose of the Study:
- To investigate the mechanisms of centrosome clustering in cancer cells.
- To explore the potential of targeting centrosome clustering for cancer therapy.
- To propose a model for centrosome clustering and its disruption.
Main Methods:
- Review of seminal research on centrosome biology and cancer.
- Analysis of centrosome amplification and clustering in cancer cells.
- Development of a theoretical model for microtubule dynamics and force balance in centrosome clustering.
Main Results:
- Cancer cells utilize centrosome clustering to form a pseudo-bipolar spindle, enabling mitosis.
- Failure of this clustering leads to multipolar spindles, resulting in mitotic arrest or cell death.
- Targeting centrosome clustering offers a potential strategy for selective cancer chemotherapy.
Conclusions:
- Understanding centrosome clustering is crucial for developing novel cancer therapeutics.
- Perturbing the balance of forces involved in centrosome clustering can selectively induce cancer cell death.
- Exploiting centrosome clustering mechanisms holds promise for non-toxic, efficacious cancer treatments.

Centrosome Duplication
The primary microtubule organizing center (MTOC) in animal cells is the centrosome. A centrosome has two cylindrical centrioles at its core. Each centriole consists of nine sets of three microtubules held together by proteins. The centrioles are positioned at right angles to each other and surrounded by a shapeless protein cloud called the pericentriolar matrix, or pericentriolar material (PCM).

Separation of Sister Chromatids
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.

The Spindle Assembly Checkpoint
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...

Anaphase Promoting Complex
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...
