Summary
Supernumerary centrosomes (excess centrosomes) can alter primary cilium number and cell signaling. This review explores how extra centrosomes contribute to cilia-related diseases.
Area of Science:
- Cell Biology
- Molecular Biology
- Genetics
Background:
- The centrosome is a key microtubule-organizing center in animal cells, influencing cytoskeleton organization and primary cilium assembly.
- Centrosomes and cilia are crucial for cell signaling, motility, and sensory functions.
- Precise regulation of centrosome and cilium number is vital; defects cause ciliopathies and potentially cancer.
Purpose of the Study:
- To review recent findings linking centrosome amplification to alterations in cilium number and signaling.
- To discuss the role of supernumerary centrosomes in cilia-related disease phenotypes.
Main Methods:
- Literature review of recent research findings.
- Analysis of studies investigating centrosome number regulation and cilia function.
- Synthesis of data connecting centrosome amplification to disease.
Main Results:
- Centrosome amplification is linked to changes in primary cilium number and signaling capacity.
- Supernumerary centrosomes may contribute to the pathogenesis of ciliopathies.
- Dysregulation of centrosome number is implicated in genome instability and tumor formation.
Conclusions:
- Supernumerary centrosomes represent a critical factor in understanding cilia-related diseases.
- Further research into the centrosome-cilium-disease axis is warranted.
- Targeting centrosome amplification could offer therapeutic strategies for ciliopathies.

Microtubules in Signaling
The primary cilium, made up of microtubules, acts as antennae on the cell surfaces for relaying external stimuli into the cells. These fine hair-like structures are present, generally one per cell. These are non-motile cilia in a 9+0 microtubules arrangement, where the central pair of microtubules are absent. The primary cilia arise from the basal body embedded in the cell membrane. Intraflagellar transport (IFT) carries requisite proteins from the cytoplasm to the cilium because the primary...
Mechanism of Ciliary Motion
The ciliary structures were first seen in 1647 by Antonie Leeuwenhoek while observing the protozoans. In lower organisms, these appendages are responsible for cell movement, while in higher organisms, these appendages help in the movement of the extracellular fluids within the body cavities.
The cilia are made up of microtubules in a 9+2 arrangement, with nine microtubule doublet ring bundles, surrounding a pair of central singlet microtubule bundles. The doublet microtubule bundles are...

Microtubules in Cell Motility
Microtubules are thick hollow cylindrical proteins that help form the cytoskeleton. Microtubules have varied roles in the cell. These filaments help form cellular appendages like cilia and flagella, which are responsible for locomotion. The cilia arise from basal bodies, separated from the main body by a membrane-like structure forming the transition zone. This zone is the gate for the entry of lipids and proteins, creating a unique composition of lipids and proteins in the ciliary membrane and...
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.

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).
