Insights into mitotic checkpoint by integrating CRISPR and RNAi

Molecular & Cellular Oncology, 2019
Our recent study of the mitotic checkpoint protein BUB1 (budding uninhibited by benzimidazoles 1) revealed several apparent BUB1 knock-out cell lines expressing low levels of BUB1 protein sufficient to support spindle assembly checkpoint activity.

DNA damage activates the SAC in an ATM/ATR-dependent manner, independently of the kinetochore. [PDF]

PLoS Genetics, 2008
The DNA damage checkpoint and the spindle assembly checkpoint (SAC) are two important regulatory mechanisms that respond to different lesions. The DNA damage checkpoint detects DNA damage, initiates protein kinase cascades, and inhibits the cell cycle ...

SUMOylation inhibits FOXM1 activity and delays mitotic transition [PDF]

, 2014
The forkhead box transcription factor FOXM1 is an essential effector of G2/M-phase transition, mitosis and the DNA damage response. As such, it is frequently deregulated during tumorigenesis. Here we report that FOXM1 is dynamically modified by SUMO1 but

Development of Styryl‐Modified 3,4‐Dihydropyrimidin‐2(1H)‐ones as Potential Antitumor Agents

ChemMedChem, Volume 21, Issue 7, 14 April 2026.
Styryl‐modified 3,4‐dihydropyrimidin‐2(1H)‐ones (DHPMs), designed from the Eg5 inhibitor monastrol, show markedly enhanced antiproliferative activity in HeLa and MCF‐7 cancer cells. Lead compounds 16 and 17 trigger apoptosis through cell‐line‐specific pathways and downregulate c‐Myc, emerging as promising anticancer candidates.

USP9X Limits Mitotic Checkpoint Complex Turnover to Strengthen the Spindle Assembly Checkpoint and Guard against Chromosomal Instability

Cell Reports, 2018
Summary: Faithful chromosome segregation during mitosis depends on the spindle assembly checkpoint (SAC), which delays progression through mitosis until every chromosome has stably attached to spindle microtubules via the kinetochore.

Role of the Putative Zinc Finger Domain of Saccharomyces cerevisiae DNA Polymerase epsilon in DNA Replication and the S/M Checkpoint Pathway [PDF]

, 1998
It has been proposed that C-terminal motifs of the catalytic subunit of budding yeast polymerase (pol) epsilon (POL2) couple DNA replication to the S/M checkpoint (Navas, T. A., Zheng, Z., and Elledge, S. J. (1995) Cell 80, 29-39).

Mitotic cell death induction by targeting the mitotic spindle with tubulin-inhibitory indole derivative molecules [PDF]

, 2017
Tubulin-targeting molecules are widely used cancer therapeutic agents. They inhibit microtubule-based structures, including the mitotic spindle, ultimately preventing cell division.

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 ...

ULK1 phosphorylates Mad1 to regulate spindle assembly checkpoint

Nucleic Acids Research, 2019
AbstractThe spindle assembly checkpoint (SAC) ensures the fidelity of chromosome segregation during mitosis. Here, we show that ULK1, a serine/threonine kinase that plays a key role in initiation of autophagy, also has an important function in the activation of SAC.

Cellular response upon proliferation in the presence of an active mitotic checkpoint

Life Science Alliance, 2019
Cells that replicate with an active mitotic checkpoint remain capable to mount multiple times an efficient arrest, are bigger than unperturbed cells, rely more heavily on Cdh1, and have an altered protein expression profile. Eukaryotic cells treated with
