Exotic mitotic mechanisms [PDF]
The emergence of eukaryotes around two billion years ago provided new challenges for the chromosome segregation machineries: the physical separation of multiple large and linear chromosomes from the microtubule-organizing centres by the nuclear envelope.

Mitofusin 1 Drives Preimplantation Development by Enhancing Chromatin Incorporation of Histone H3.3
MFN1 exerts its function partially through histone H3.3 in early embryos. MFN1 colocalizes with PADI6, and its deficiency results in compromised cytoplasmic lattices and ribosomal subunits, leading to declined H3.3 protein level. This, in turn, hinders the incorporation of H3.3 into the embryonic genome, thereby causing failure of male pronucleus ...

Mitotic regulation by NIMA-related kinases
The NIMA-related kinases represent a family of serine/threonine kinases implicated in cell cycle control. The founding member of this family, the NIMA kinase of Aspergillus nidulans, as well as the fission yeast homologue Fin1, contribute to multiple ...

Dense periodic packings of tori [PDF]
Dense packings of nonoverlapping bodies in three-dimensional Euclidean space are useful models of the structure of a variety of many-particle systems that arise in the physical and biological sciences. Here we investigate the packing behavior of congruent ring tori, which are multiply connected nonconvex bodies of genus 1, as well as horn and spindle ...

LET-99 functions in the astral furrowing pathway, where it is required for myosin enrichment in the contractile ring. [PDF]
The anaphase spindle determines the position of the cytokinesis furrow, such that the contractile ring assembles in an equatorial zone between the two spindle poles.

Early synapsids neurosensory diversity revealed by CT and synchrotron scanning
Abstract Non‐mammaliaform synapsids (NMS) represent the closest relatives of today's mammals among the early amniotes. Exploring their brain and nervous system is key to understanding how mammals evolved. Here, using CT and Synchrotron scanning, we document for the first time three extreme cases of neurosensory and behavioral adaptations that probe ...

The role of gene dosage in budding yeast centrosome scaling and spontaneous diploidization.
Ploidy is the number of whole sets of chromosomes in a species. Ploidy is typically a stable cellular feature that is critical for survival. Polyploidization is a route recognized to increase gene dosage, improve fitness under stressful conditions and ...

Chromosome Oscillations in Mitosis [PDF]
Successful cell division requires a tight regulation of chromosome motion via the activity of molecular motors. Many of the key players at the origin of the forces generating the movement have been identified, but their spatial and temporal organization remains elusive.

A comparison of the distribution of actin and tubulin in the mammalian mitotic spindle as seen by indirect immunofluorescence [PDF]
Rabbit antibodies against actin and tubulin were used in an indirect immunofluorescence study of the structure of the mitotic spindle of PtK1 cells after lysis under conditions that preserve anaphase chromosome movement. During early prophase there is no
