Different from mitosis, the female meiosis undergoes asymmetric division that produces haploid oocytes and polar body, which is essential for retaining maternal components to support subsequent fertilization and embryo development. However, the underlying mechanisms are still largely unknown.

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.

Analysis of a Spindle Pole Body Mutant Reveals a Defect in Biorientation and Illuminates Spindle Forces [PDF]
The spindle pole body (SPB) is the microtubule organizing center in Saccharomyces cerevisiae. An essential task of the SPB is to ensure assembly of the bipolar spindle, which requires a proper balancing of forces on the microtubules and chromosomes. The SPB component Spc110p connects the ends of the spindle microtubules to the core of the SPB.

Two New Cases Expand the Phenotypic Spectrum of TUBG1 Missense Variants
ABSTRACT The gamma‐tubulin ring complex (γ‐TuRC) plays a role in coordinating centrosome and spindle pole body formation during cell division. TUBG1 encodes a critical component of the γ‐TuRC. Pathogenic TUBG1 variants can cause a range of alterations in cortical gyral patterning, microcephaly, and other neurological manifestations.

Interaction of CK1δ with γTuSC ensures proper microtubule assembly and spindle positioning. [PDF]
Casein kinase 1δ (CK1δ) family members associate with microtubule-organizing centers (MTOCs) from yeast to humans, but their mitotic roles and targets have yet to be identified.

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 ...

An Extended, Boolean Model of the Septation Initiation Network in S.Pombe Provides Insights into Its Regulation. [PDF]
Cytokinesis in fission yeast is controlled by the Septation Initiation Network (SIN), a protein kinase signaling network using the spindle pole body as scaffold.
