Cell Cycle‐Specific Regulation of Centrosome Clustering Dynamics in Cancer Cells by the Multifunctional Kinesin HSET

Advanced Science, Volume 13, Issue 26, 8 May 2026.
CDK5RAP2 associates with the kinesin HSET and forms co‐condensates. HSET motors drive the directional transport of CDK5RAP2 condensates toward microtubule minus ends. During mitosis, HSET self‐assembly further stabilizes clustered centrosomes, thereby enabling pseudo‐bipolar spindle formation in cancer cells with supernumerary centrosomes. Upon mitotic

Mild replication stress causes premature centriole disengagement via a sub-critical Plk1 activity under the control of ATR-Chk1

Nature Communications, 2023
A tight synchrony between the DNA and centrosome cycle is essential for genomic integrity. Centriole disengagement, which licenses centrosomes for duplication, occurs normally during mitotic exit. We recently demonstrated that mild DNA replication stress

Serum Proteomic Analysis Using Gel‐Based Liquid Chromatography Tandem Mass Spectrometry Reveals Differences Between Canine Oral Malignancies and Non‐Malignant Conditions

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
This study establishes a GeLC‐MS/MS‐based serum proteomics workflow for canine oral oncology to differentiate malignancies from non‐malignant conditions. Comprehensive protein profiling, pathway analysis and protein–drug interaction mapping reveal candidate biomarkers and insights into the pathogenesis of canine oral cancers.

Centrin-2 Is Required for Centriole Duplication in Mammalian Cells [PDF]

Current Biology, 2002
Centrosomes are the favored microtubule-organizing framework of eukaryotic cells. Centrosomes contain a pair of centrioles that normally duplicate once during the cell cycle to give rise to two mitotic spindle poles, each containing one old and one new centriole. However, aside from their role as an anchor point for pericentriolar material and as basal

PLK4 is a potential therapeutic target in nonmelanoma skin cancers: Evidence from molecular and in vivo studies

Photochemistry and Photobiology, Volume 102, Issue 3, Page 560-576, May/June 2026.
Exposure to solar ultraviolet radiation is the main etiologic driver of nonmelanoma skin cancers (NMSCs), including basal cell (BCC) and cutaneous squamous cell carcinomas (cSCC), which are the most prevalent types of cancers in the US. In this study, we demonstrate that the serine/threonine kinase Polo‐like kinase 4 (PLK4) is overexpressed in NMSCs ...

Phase separation of Polo-like kinase 4 by autoactivation and clustering drives centriole biogenesis

Nature Communications, 2019
Regulation of centriole duplication is essential for normal chromosome segregation and the maintenance of genomic stability, and Polo-like kinase 4 (Plk4) is a known regulator with unclear mechanisms.

Integrity of the Pericentriolar Material Is Essential for Maintaining Centriole Association during M Phase.

PLoS ONE, 2015
A procentriole is assembled next to the mother centriole during S phase and remains associated until M phase. After functioning as a spindle pole during mitosis, the mother centriole and procentriole are separated at the end of mitosis.

NuSAP Safeguards Centriole Integrity to Mediate CEP57‐CEP152 Torus Recruitment for Proper Engagement

Advanced Science, Volume 13, Issue 19, 2 April 2026.
This study reveals a novel role for the microtubule stabilizer NuSAP at centrioles. NuSAP depletion destabilizes the centriole's tubulin structure, causing premature disengagement, PCM defects, and mis‐localization of the CEP57‐CEP63‐CEP152 complex. By reinforcing centriole architecture, NuSAP enables early CEP57 loading and initiates a newly proposed ...

9-fold symmetry is not essential for centriole elongation and formation of new centriole-like structures

Nature Communications
As daughter centrioles assemble during G2, they recruit conserved Ana3/RTTN followed by its partner Rcd4/PPP1R35. Together, this contributes to the subsequent recruitment of Ana1/CEP295, required for the centriole’s conversion to a centrosome.

Revisiting Centrioles in Nematodes—Historic Findings and Current Topics

Cells, 2018
Theodor Boveri is considered as the “father” of centrosome biology. Boveri’s fundamental findings have laid the groundwork for decades of research on centrosomes.
