Specialisation of meiotic kinetochores revealed through a synthetic spindle assembly checkpoint strategy [PDF]

eLife
Meiosis creates haploid gametes through two sequential M phases. While many studies have focused on meiosis I, the molecular events which drive and define meiosis II are largely unknown.

Metaphase Spindle Assembly

Biology, 2017
A microtubule-based bipolar spindle is required for error-free chromosome segregation during cell division. In this review I discuss the molecular mechanisms required for the assembly of this dynamic micrometer-scale structure in animal cells.

Automated Cytogenetic Biodosimetry at Population-Scale

Radiation, 2021
The dicentric chromosome (DC) assay accurately quantifies exposure to radiation; however, manual and semi-automated assignment of DCs has limited its use for a potential large-scale radiation incident.

Cytogenetic of Brachyura (Decapoda): testing technical aspects for obtaining metaphase chromosomes in six mangrove crab species

Caryologia, 2020
Brachyura is one of the most specious infra-order belonging to Decapoda and it plays a central role from an ecological and economic point of view. Despite its importance, cytogenetic studies on Brachyura (Decapoda) are extremely limited due to the ...

Ca2+ Release by IP3 Receptors Is Required to Orient the Mitotic Spindle

Cell Reports, 2020
Summary: The mitotic spindle distributes chromosomes evenly to daughter cells during mitosis. The orientation of the spindle, guided by internal and external cues, determines the axis of cell division and thereby contributes to tissue morphogenesis ...

The turtle and the rabbit story in a modern (PI3)key

Molecular & Cellular Oncology, 2018
Mitosis is a complex process controlling proper distribution of chromosomes and preventing genomic instability, a typical hallmark of cancer. We recently reported that that a class II isoform of Phosphoinositide 3-kinase (PI3K), PI3K-C2α, is involved in ...
