Insights

Centrosomes, crucial for cell division, are implicated in genetic instability when defective. Tumor suppressors at centrosomes regulate their function, highlighting a link between centrosome control and genetic stability.

Area of Science:

  • Cell Biology
  • Genetics

Background:

  • Centrosomes function as microtubule organizing centers and spindle poles during mitosis.
  • Centrosome defects are linked to genetic instability.
  • Mammalian centrosome regulators are often predicted from model systems.

Purpose of the Study:

  • Investigate the role of centrosomes in cellular processes beyond mitosis.
  • Explore the connection between centrosome defects and genetic instability.
  • Identify regulators of mammalian centrosome function.

Main Methods:

  • Review of recent research on centrosome function.
  • Analysis of genetic instability associated with centrosome defects.
  • Identification of known tumor suppressors localized at centrosomes.

Main Results:

  • Centrosomes are involved in multiple cellular processes.
  • Centrosome dysfunction leads to genetic instability.
  • Several known tumor suppressors localize to centrosomes.
  • These tumor suppressors influence centrosome duplication and function.

Conclusions:

  • Control of centrosome function is critical for maintaining genetic stability.
  • The localization and function of tumor suppressors at centrosomes are key to this regulation.

Centrosome Duplication02:25

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).
To ensure that each daughter cell receives a centrosome after cell division, centrosome duplication...

Centrioles and Centrosomes01:13

Centrioles and Centrosomes

Most animal cells comprise a pair of centrioles together called a centrosome. The cell duplicates its centrosome and contains two centrosomes side-by-side, which begin to move apart during the prophase. As the centrosomes migrate to two different sides of the cell, microtubules start extending from each centrosome toward the other end. The mitotic spindle is composed of the centrosomes and their emerging microtubules.
Near the end of the prophase, also called late prophase or "prometaphase,"...

Cancer-Critical Genes II: Tumor Suppressor Genes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

Loss of Tumor Suppressor Gene Functions

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
