Regulation of AURORA B function by mitotic checkpoint protein MAD2 [PDF]
Cell cycle checkpoint signaling stringently regulates chromosome segregation during cell division. MAD2 is one of the key components of the spindle and mitotic checkpoint complex that regulates the fidelity of cell division along with MAD1, CDC20, BUBR1,

Cytogenetic quantification of KNL1‐labelled kinetochores in Ornithogalum kochii reveals a significant positive scaling relationship between chromosome size and kinetochore size, demonstrating that chromosome–kinetochore scaling operates even across moderate intra‐karyotype size variation.

The Spindle Assembly Checkpoint: Clock or Domino?
In each cell division, the newly duplicated chromosomes must be evenly distributed between the sister cells. Errors in this process during meiosis or mitosis are equally fatal: improper segregation of the chromosome 21 during human meiosis leads to Down syndrome (Conley, Aneuploidy: etiology and mechanisms, pp 35-89, 1985), whereas in somatic cells ...

Precocious activation of APC/C-Cdh1 at pre-anaphase causes genome instability [PDF]
Faithful chromosome segregation and thereby accurate gene transmission are crucial for all organisms. Until proper attachment of the mitotic spindle to the kinetochore is established, the ubiquitin ligase (E3) Cdc20-activated APC/C (anaphase promoting ...

ABSTRACT Equine melanocytic neoplasms (EMN) are aggressive tumours characterised by high metastatic potential and limited therapeutic options available. However, the molecular mechanisms underlying their progression remain poorly understood. This study therefore presents the integrative phosphoproteomic analysis of EMN tissue, with the aim of ...

The equatorial position of the metaphase plate ensures symmetric cell divisions
Chromosome alignment in the middle of the bipolar spindle is a hallmark of metazoan cell divisions. When we offset the metaphase plate position by creating an asymmetric centriole distribution on each pole, we find that metaphase plates relocate to the ...

USP49 deubiquitinase regulates the mitotic spindle checkpoint and prevents aneuploidy
The spindle assembly checkpoint (SAC) is an essential mechanism that ensures the accurate chromosome segregation during mitosis, thus preventing genomic instability.

Mitotic centromere-associated kinesin (MCAK) : a potential cancer drug target [PDF]
The inability to faithfully segregate chromosomes in mitosis results in chromosome instability, a hallmark of solid tumors. Disruption of microtubule dynamics contributes highly to mitotic chromosome instability.

Biomaterial Physical Cues as Gene Regulators for Cellular Agriculture
This review elucidates how biomaterial physical cues—ranging from matrix stiffness to remote electromagnetic fields—serve as extrinsic regulators of gene expression in cellular agriculture. By identifying central mechanotransduction pathways that bridge physical inputs to genetic remodeling, the authors propose the “Material Genome” concept: a ...
