Insights

Human NDR kinases regulate centrosome duplication, a key process in cell division. This study reveals NDR

Area of Science:

  • Cell Biology
  • Molecular Biology
  • Cancer Research

Background:

  • Human NDR kinases are implicated in cancer but their specific functions are largely unknown.
  • Centrosome duplication is a critical process for accurate cell division.

Purpose of the Study:

  • To elucidate the function of mammalian NDR kinases in cellular processes.
  • To investigate the role of human NDR in centrosome duplication.

Main Methods:

  • Localization studies of endogenous NDR at centrosomes during the cell cycle.
  • Functional assays using NDR overexpression, kinase-dead mutants, and siRNA-mediated depletion.
  • Investigating the interplay between NDR and Cdk2 activity in centrosome amplification.

Main Results:

  • Human NDR kinase localizes to centrosomes in a cell-cycle-dependent manner.
  • NDR kinase activity is essential for proper centrosome duplication; its overexpression leads to overduplication.
  • NDR-driven centrosome duplication requires Cdk2 activity.

Conclusions:

  • This study identifies the first known function of a mammalian NDR kinase: direct contribution to centrosome duplication.
  • The findings suggest a molecular link between NDR kinases, centrosome overduplication, and cancer development.

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,"...
M-Cdk Drives Transition Into Mitosis02:15

M-Cdk Drives Transition Into Mitosis

Checkpoints throughout the cell cycle serve as safeguards and gatekeepers, allowing the cell cycle to progress in favorable conditions and slow or halt it in problematic ones. This regulation is known as the cell cycle control system.
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.

Attachment of Sister Chromatids02:57

Attachment of Sister Chromatids

As cells progress into mitosis, the nuclear envelope breaks down, and the condensed chromosomes are exposed to the array of bipolar microtubules of the mitotic spindle. The kinetochore, a large, disc-shaped protein complex, is present at the centromere region of the sister chromatids and acts as a binding site for the microtubules.  Usually, the plus-end of a single microtubule is embedded within the kinetochore. However, some kinetochores first establish lateral contact with the side-wall of a...
