Specific detection of fission yeast primary septum reveals septum and cleavage furrow ingression during early anaphase independent of mitosis completion.

PLoS Genetics, 2018
It is widely accepted in eukaryotes that the cleavage furrow only initiates after mitosis completion. In fission yeast, cytokinesis requires the synthesis of a septum tightly coupled to cleavage furrow ingression.

Separase prevents genomic instability by controlling replication fork speed [PDF]

, 2016
Proper chromosome segregation is crucial for preserving genomic integrity, and errors in this process cause chromosome mis-segregation, which may contribute to cancer development.

The checkpoint delaying anaphase in response to chromosome monoorientation is mediated by an inhibitory signal produced by unattached kinetochores

Journal of Cell Biology, 1995
During mitosis in Ptk1 cells anaphase is not initiated until, on average, 23 +/- 1 min after the last monooriented chromosome acquires a bipolar attachment to the spindle--an event that may require 3 h (Rieder, C. L., A. Schultz, R. W.

Ecotoxicological Evaluation of the Antimicrobial Butylparaben in Edaphic Organisms Using Multiple Biomarkers

Environmental Toxicology, EarlyView.
ABSTRACT Butylparaben (BuP) recurrently contaminates soils worldwide, mainly by incorporating sewage sludge into cultivated areas, using wastewater in irrigation, and leaching contaminated soils. However, there are few studies on the ecotoxicological effects of this paraben on edaphic organisms.

Ecotoxicological Evaluation of Organic Sunscreens Used Worldwide, Alone and in Mixture, on Terrestrial Plants

Environmental Toxicology, EarlyView.
ABSTRACT The environmental hazards of sunscreens are discussed worldwide. However, there are few ecotoxicological studies on these compounds alone for edaphic organisms, and none for their mixtures. Avobenzone (1 and 10 ng/L), octocrylene (10 and 100 μg/L), and oxybenzone (2 and 20 μg/L), alone and in binary combinations (between the lowest and the ...

Blocking microtubule deacetylation inhibits anaphase chromosome movements in crane-fly spermatocytes.

PLoS ONE
Chromosome movement speeds during anaphase are regulated by depolymerization of microtubules. Several models describe chromosome movement during cell division but none of them consider post-translational modifications of tubulin, even though such ...

Transcription Factor TCF12‐Mediated Maternal Gene Expressions in Mouse Oocyte Are Prerequisites of Successful Fertilisation and Zygotic Genome Activation

Cell Proliferation, EarlyView.
Maternal TCF12 ensures the competence of fertilisation by controlling the expression of Astl and the proper location of cortical granules. Furthermore, maternal TCF12 maintains the phosphatase activity of PP2A by regulating the expression of Arpp19. Oocyte‐specific deletion of Tcf12 leads to fertilisation defects as well as ZGA failure at the 2‐cell ...

Development of NAFLD‐Specific Human Liver Organoid Models on a Microengineered Array Chip for Semaglutide Efficacy Evaluation

Cell Proliferation, EarlyView.
Microporous array organ chips were integrated with commercially available well plates to develop organoid chip platforms, which enable modelling of hepatic physiology and non‐alcoholic fatty liver disease (NAFLD) pathogenesis, as well as evaluation of semaglutide therapeutics. ABSTRACT Progressive non‐alcoholic fatty liver disease (NAFLD) may culminate

SOX30 Governs Synaptonemal Complex Assembly and Homologous Recombination in Male Meiosis

Cell Proliferation, EarlyView.
The transcription factor SOX30 directly binds promoter regions of SYCE1 and SYCE2 to mediate their transcriptional activation, thereby enabling proper assembly of central elements within the synaptonemal complex. Structural destabilisation of the synaptonemal complex in Sox30 KK spermatocytes triggers synaptic discontinuity, impairs homologous ...
