53BP1 and USP28 mediate p53-dependent cell cycle arrest in response to centrosome loss and prolonged mitosis

open access: yeseLife, 2016
Mitosis occurs efficiently, but when it is disturbed or delayed, p53-dependent cell death or senescence is often triggered after mitotic exit. To characterize this process, we conducted CRISPR-mediated loss-of-function screens using a cell-based assay in

PartMitosis: A Partially Supervised Deep Learning Framework for Mitosis Detection in Breast Cancer Histopathology Images

open access: yesIEEE Access, 2020
Detection of mitotic tumor cells per tissue area is one of the critical markers of breast cancer prognosis. The aim of this paper is to develop a method for the automatic detection of mitotic figures from breast cancer histological slides using a ...

PREEParing for Mitosis [PDF]

open access: yesDevelopmental Cell, 2013
Reporting in Developmental Cell, Schlaitz et al. (2013) show that endoplasmic reticulum (ER) membrane exclusion from the mitotic spindle is an active process requiring REEP membrane proteins. REEP protein depletion results in ER membrane retention on the spindle and chromosomes, leading to defects in chromosome segregation and nuclear envelope assembly.

Investigation of FEAR and MEN pathway homologs in multinucleate cells [PDF]

open access: yes, 2011
The cell cycle is a sequence of events enabling a cell to replicate and proliferate. Common landmark events in most eukaryotic cell cycles are duplication of the DNA, mitosis, and cell separation.

The Biochemistry of Mitosis [PDF]

open access: yesCold Spring Harbor Perspectives in Biology, 2015
In this article, we will discuss the biochemistry of mitosis in eukaryotic cells. We will focus on conserved principles that, importantly, are adapted to the biology of the organism. It is vital to bear in mind that the structural requirements for division in a rapidly dividing syncytial Drosophila embryo, for example, are markedly different from those

Mitosis Detection in Breast Histopathology Images Using a Self-Attention-Enhanced Faster R-CNN Framework

open access: yesIEEE Access
At present, mitosis detection in breast histopathology images is a critical issue for breast cancer grading. Due to the breast tissue having a complex structure, and mitosis and non-mitosis cells being similar to each other, traditional methods for ...

Fcp1 phosphatase controls Greatwall kinase to promote PP2A-B55 activation and mitotic progression

open access: yeseLife, 2015
During cell division, progression through mitosis is driven by a protein phosphorylation wave. This wave namely depends on an activation-inactivation cycle of cyclin B-dependent kinase (Cdk) 1 while activities of major protein phosphatases, like PP1 and ...

Mitosis sans Mitosis: The Mitotic Oscillator in Differentiation [PDF]

open access: yesDevelopmental Cell, 2017
Differentiation and proliferation are usually considered to be antagonistic partners in development. However, in a recent issue of Science, Al Jord et al. (2017) show that key regulators of the mitotic cycle are redeployed in differentiating multiciliated cells to promote ciliogenesis without mitotic progression.

Cigarette smoke condensate induces centrosome clustering in normal lung epithelial cells

open access: yesCancer Medicine, 2023
Background Unlike normal cells, cancer cells frequently have multiple centrosomes that can cluster to form bipolar mitotic spindles and allow for successful cell division.

An unmet actin requirement explains the mitotic inhibition of clathrin-mediated endocytosis [PDF]

open access: yes, 2014
Clathrin-mediated endocytosis (CME) is the major internalisation route for many different receptor types in mammalian cells. CME is shut down during early mitosis, but the mechanism of this inhibition is unclear.
