[HTML][HTML] Spindle assembly checkpoint activation and silencing at kinetochores

P Lara-Gonzalez, J Pines, A Desai - Seminars in cell & developmental …, 2021 - Elsevier
The spindle assembly checkpoint (SAC) is a surveillance mechanism that promotes
accurate chromosome segregation in mitosis. The checkpoint senses the attachment state of …

Triggering mitosis

A Crncec, H Hochegger - FEBS letters, 2019 - Wiley Online Library
Entry into mitosis is triggered by the activation of cyclin‐dependent kinase 1 (Cdk1). This
simple reaction rapidly and irreversibly sets the cell up for division. Even though the core …

The SNHG1-centered ceRNA network regulates cell cycle and is a potential prognostic biomarker for hepatocellular carcinoma

L Zhou, Q Zhang, H Deng, S Ou, T Liang… - The Tohoku Journal of …, 2022 - jstage.jst.go.jp
Hepatocellular carcinoma (HCC) is one of the most common and lethal types of cancer. This
study aimed to identify the expression regulatory network and a prognostic signature of …

MPS1 localizes to end-on microtubule-attached kinetochores to promote microtubule release

D Hayward, E Roberts, U Gruneberg - Current Biology, 2022 - cell.com
In eukaryotes, the spindle assembly checkpoint protects genome stability in mitosis by
preventing chromosome segregation until incorrect microtubule-kinetochore attachment …

Orchestration of the spindle assembly checkpoint by CDK1‐cyclin B1

D Hayward, T Alfonso‐Pérez, U Gruneberg - FEBS letters, 2019 - Wiley Online Library
In mitosis, the spindle assembly checkpoint (SAC) monitors the formation of microtubule‐
kinetochore attachments during capture of chromosomes by the mitotic spindle. Spindle …

Cyclin A triggers Mitosis either via the Greatwall kinase pathway or Cyclin B

N Hégarat, A Crncec… - The EMBO …, 2020 - embopress.org
Two mitotic cyclin types, cyclin A and B, exist in higher eukaryotes, but their specialised
functions in mitosis are incompletely understood. Using degron tags for rapid inducible …

MAD1-dependent recruitment of CDK1-CCNB1 to kinetochores promotes spindle checkpoint signaling

T Alfonso-Pérez, D Hayward, J Holder… - Journal of Cell …, 2019 - rupress.org
Cyclin B–dependent kinase (CDK1-CCNB1) promotes entry into mitosis. Additionally, it
inhibits mitotic exit by activating the spindle checkpoint. This latter role is mediated through …

Cyclin B1 scaffolds MAD 1 at the kinetochore corona to activate the mitotic checkpoint

LA Allan, M Camacho Reis, G Ciossani… - The EMBO …, 2020 - embopress.org
Cyclin B: CDK 1 is the master kinase regulator of mitosis. We show here that, in addition to
its kinase functions, mammalian Cyclin B also scaffolds a localised signalling pathway to …

UHRF1 promotes spindle assembly and chromosome congression by catalyzing EG5 polyubiquitination

X Qi, Y Liu, Y Peng, Y Fu, Y Fu, L Yin, X Li - Journal of Cell Biology, 2023 - rupress.org
UHRF1 is an epigenetic coordinator bridging DNA methylation and histone modifications.
Additionally, UHRF1 regulates DNA replication and cell cycle, and its deletion induces G1/S …

Cyclin B1-Cdk1 facilitates MAD1 release from the nuclear pore to ensure a robust spindle checkpoint

M Jackman, C Marcozzi, M Barbiero, M Pardo… - Journal of Cell …, 2020 - rupress.org
How the cell rapidly and completely reorganizes its architecture when it divides is a problem
that has fascinated researchers for almost 150 yr. We now know that the core regulatory …
