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).

TRAIP is a regulator of the spindle assembly checkpoint. [PDF]

, 2014
Accurate chromosome segregation during mitosis is temporally and spatially coordinated by fidelity-monitoring checkpoint systems. Deficiencies in these checkpoint systems can lead to chromosome segregation errors and aneuploidy, and promote tumorigenesis.

Titin Is Present in the Elastic Tethers That Connect Separating Anaphase Chromosomes in Crane‐Fly Spermatocytes

Cytoskeleton, EarlyView.
ABSTRACT Elastic tethers connect telomeres of separating chromosomes in anaphase of animal cells. Immunofluorescence staining of titin in crane‐fly spermatocytes, using 4 different antibodies, shows that the giant elastic protein titin seems to be a component of mitotic tethers: titin “strands” extend between separating chromosomes, connecting their ...

A minimal deterministic model reveals integration of spindle assembly and position checkpoints in mitosis

Scientific Reports
The spindle assembly checkpoint (SAC) and spindle position checkpoint (SPOC) are essential surveillance systems that ensure accurate chromosome segregation and proper spindle orientation during mitosis.

How to halve ploidy : lessons from budding yeast meiosis [PDF]

, 2012
Maintenance of ploidy in sexually reproducing organisms requires a specialized form of cell division called meiosis that generates genetically diverse haploid gametes from diploid germ cells.

Intravenous Lipopolysaccharide Challenge in Healthy Participants Reveals Pharmacodynamic Markers in Blood and Bone Marrow for Early‐Phase Oncology Drug Development

Clinical Pharmacology &Therapeutics, EarlyView.
Demonstrating pharmacological effects in early‐phase oncology clinical trials remains challenging, largely due to the lack of robust pharmacodynamic markers. Lipopolysaccharide (LPS) is used as an immune challenge agent in healthy participants to study drugs for autoimmune conditions.

CDK5RAP2 is required for spindle checkpoint function [PDF]

Cell Cycle, 2009
The combination of paclitaxel and doxorubicin is among the most successful chemotherapy regimens in cancer treatment. CDK5RAP2, when mutated, causes primary microcephaly. We show here that inhibition of CDK5RAP2 expression causes chromosome mis-segregation, fails to maintain the spindle checkpoint, and is associated with reduced expression of the ...

Hypoxia Induces a Mitotic Survival Advantage After Radiotherapy in Head and Neck Cancer Cells

International Journal of Cancer, EarlyView.
Hypoxic tumor environments significantly limit radiotherapy effectiveness against cancer, particularly in head and neck squamous cell carcinoma (HNSCC). Here, the authors tracked hypoxic and post‐hypoxic cells using a hypoxia‐fate mapping system in human papillomavirus (HPV)‐positive and HPV‐negative HNSCC models.

An important role for Myb-MuvB and its target gene KIF23 in a mouse model of lung adenocarcinoma [PDF]

, 2016
The conserved Myb-MuvB (MMB) multiprotein complex has an important role in transcriptional activation of mitotic genes. MMB target genes are overexpressed in several different cancer types and their elevated expression is associated with an advanced ...

Cytogenotoxic Effects of Fluopyram in Allium cepa Root Cells Involving Microtubule Disruption

Environmental Toxicology, EarlyView.
ABSTRACT Fluopyram is a next‐generation fungicide widely used in agriculture; however, its persistence in soils and mobility toward aquatic systems have raised concerns regarding potential ecotoxicological risks. This study evaluated the cytogenotoxic effects of a commercial fluopyram‐based pesticide formulation on Allium cepa root meristem cells ...
