The RZZ Complex and the Spindle Assembly Checkpoint

Cell Structure and Function, 2009
The conserved protein Rod is found in various organisms. It is localized on the kinetochores or spindle microtubules during cell division. Rod is required for proper chromosome segregation during both mitosis and meiosis. The effects of rod mutations are similar for both equational and reductional divisions, giving rise to anaphases with lagging ...

Spindle assembly checkpoint activation and silencing at kinetochores

Seminars in Cell & Developmental Biology, 2021
The spindle assembly checkpoint (SAC) is a surveillance mechanism that promotes accurate chromosome segregation in mitosis. The checkpoint senses the attachment state of kinetochores, the proteinaceous structures that assemble onto chromosomes in mitosis in order to mediate their interaction with spindle microtubules.

A screen for selective killing of cells with chromosomal instability induced by a spindle checkpoint defect. [PDF]

PLoS ONE, 2012
The spindle assembly checkpoint is crucial for the maintenance of a stable chromosome number. Defects in the checkpoint lead to Chromosomal INstability (CIN), which is linked to the progression of tumors with poor clinical outcomes such as drug ...

Advances in 3D Bioprinting for Breast Cancer Modeling: Tumor Microenvironment, Metastasis, and Drug Screening

Advanced Healthcare Materials, EarlyView.
Three‐dimensional bioprinting transforms breast cancer modeling from simple constructs into spatially organized, multicellular, perfused, and patient‐derived platforms. This review shows how bioinks, cellular composition, architecture, and flow govern tumor behavior and drug response, while revealing why complexity alone is insufficient without ...

Investigation into how mitotic spindle checkpoint function is compromised by Sv40 large T antigen. [PDF]

, 2005
The viral oncoprotein Simian virus 40 large T antigen (LT) efficiently immortalises primary rodent cells and occasionally transforms them to tumourigenicity.

Dual pathway spindle assembly increases both the speed and the fidelity of mitosis [PDF]

, 2011
Roughly half of all animal somatic cell spindles assemble by the classical prophase pathway, in which the centrosomes separate ahead of nuclear envelope breakdown (NEBD).

scTIDE: Deciphering Critical Transitions Through Cell‐Perturbed Manifold Graphs and Optimal Transport Conditional Flow Matching

Advanced Science, EarlyView.
scTIDE identifies single‐cell tipping points by combining manifold‐based graph representations with optimal‐transport conditional flow matching, which preserves intrinsic topology and models distributional dynamics. It supports critical‐transition detection at individual‐cell resolution, prediction of unseen cells, and dimensionality reduction and ...

Functional characterization of PICH, a DNA-dependent ATPase required for faithful chromosome segregation during mitosis [PDF]

, 2010
PICH (Plk1-interacting checkpoint helicase), a DNA-dependent ATPase, was identified as a binding partner and substrate of Plk1. During mitosis, PICH localizes to the centromere/KTs of condensed mitotic chromosomes and to ultra-fine DNA bridges (UFBs ...

Genetic Ablation and Multi‐Omics Profiling Reveal CEP55 as a Key Driver of Tumorigenesis in Diverse Cancer Models

Advanced Science, EarlyView.
Genetic ablation of Cep55 in Pten‐deficient mouse models delays tumorigenesis. Integrated multi‐omics analyses (proteomics, phosphoproteomics, and spatial transcriptomics) reveal that CEP55 regulates oncogenic signaling (RAS/ERK, PI3K/AKT), integrin/FAK‐mediated adhesion, extracellular matrix (ECM) remodeling, and endocytosis.

Loss of APC induces polyploidy as a result of a combination of defects in mitosis and apoptosis [PDF]

, 2007
Mutations in the adenomatous polyposis coli (APC) tumor suppressor gene initiate a majority of colorectal cancers. Acquisition of chromosomal instability is an early event in these tumors.
