The Crosstalk Between CRL5 and APC/C E3 Ligases Regulates Metastasis and Chemosensitivity of Cancer Cells

open access: yesAdvanced Science, EarlyView.
This study uncovers a previously unknown crosstalk between two major ubiquitin ligases, CRL5 and APC/C. The authors identify APC11 as a binding partner of CUL5, showing that their interaction regulates neddylation, substrate stability, and mitotic progression.

Meiotic behavior of small chromosomes in maize

open access: yesFrontiers in Plant Science, 2013
The typical behavior of chromosomes in meiosis is that homologous pairs synapse, recombine and then separate at anaphase I. At anaphase II, sister chromatids separate.

Giant cell formation produced by laser microbeam irradiation of chromatin in Chinese hamster cells [PDF]

open access: yes, 1981
A pulsed laser microbeam of wavelength 532 nm was used to produce visible small lesions in the nucleoplasm or in the cytoplasm of V79 Chinese hamster cells.

TopBP1/Dpb11 binds DNA anaphase bridges to prevent genome instability

open access: yesJournal of Cell Biology, 2014
TopBP1/Dpb11 prevents accumulation of anaphase chromatin bridges by stimulating the Mec1/ATR kinase and suppressing homologous recombination.

A theoretical model of anaphase

open access: yesMathematical Biosciences
This paper develops a theory for anaphase in cells. After a brief description of microtubules, the mitotic spindle and the centrosome, a mathematical model for anaphase is introduced and developed in the context of the cell cytoplasm and liquid crystalline structures.

The Anaphase-Promoting Complex/Cyclosome Is Required for Anaphase Progression in Multinucleated Ashbya gossypii Cells [PDF]

open access: yesEukaryotic Cell, 2007
ABSTRACT Regulated protein degradation is essential for eukaryotic cell cycle progression. The anaphase-promoting complex/cyclosome (APC/C) is responsible for the protein destruction required for the initiation of anaphase and the exit from mitosis, including the degradation of securin and B-type cyclins.

Nampt-mediated spindle sizing secures a post-anaphase increase in spindle speed required for extreme asymmetry

open access: yesNature Communications, 2020
Meiotic cell division in oocytes is asymmetric and requires microtubule spindle migration after anaphase-onset. Here, the authors show that Nampt, an enzyme of the Nicotinamide adenine dinucleotide (NAD) biosynthetic pathway, contributes to post-anaphase

Dynamic SUMO remodeling drives a series of critical events during the meiotic divisions in Caenorhabditis elegans. [PDF]

open access: yesPLoS Genetics, 2018
Chromosome congression and segregation in C. elegans oocytes depend on a complex of conserved proteins that forms a ring around the center of each bivalent during prometaphase; these complexes are then removed from chromosomes at anaphase onset and ...

Meiotic cellular rejuvenation is coupled to nuclear remodeling in budding yeast. [PDF]

open access: yes, 2019
Production of healthy gametes in meiosis relies on the quality control and proper distribution of both nuclear and cytoplasmic contents. Meiotic differentiation naturally eliminates age-induced cellular damage by an unknown mechanism.

The meiosis-specific Cdc20 family-member Ama1 promotes binding of the Ssp2 activator to the Smk1 MAP kinase. [PDF]

open access: yes, 2018
Smk1 is a meiosis-specific MAP kinase (MAPK) in budding yeast that is required for spore formation. It is localized to prospore membranes (PSMs), the structures that engulf haploid cells during meiosis II (MII).
