Spindle mechanics and chromosome segregation
The Minisymposium “Spindle Mechanics and Chromosome Segregation” featured new and exciting findings related to the spindle and chromosomes during mitosis and meiosis. It covered a range of topics including spindle architecture and mechanics, kinetochore–microtubule interactions, chromosome dynamics at mitotic entry and exit, as well as mitotic errors ...

Deregulation of Chromosome Segregation and Cancer [PDF]
The mitotic spindle assembly checkpoint (SAC) is an intricate cell signaling system that ensures the high fidelity and timely segregation of chromosomes during cell division. Mistakes in this process can lead to the loss, gain, or rearrangement of the genetic material. Gross chromosomal aberrations are usually lethal but can cause birth and development

A Cohesin-Based Partitioning Mechanism Revealed upon Transcriptional Inactivation of Centromere. [PDF]
Transcriptional inactivation of the budding yeast centromere has been a widely used tool in studies of chromosome segregation and aneuploidy. In haploid cells when an essential chromosome contains a single conditionally inactivated centromere (GAL-CEN ...

SWI/SNF-like chromatin remodeling factor Fun30 supports point centromere function in S. cerevisiae [PDF]
Budding yeast centromeres are sequence-defined point centromeres and are, unlike in many other organisms, not embedded in heterochromatin. Here we show that Fun30, a poorly understood SWI/SNF-like chromatin remodeling factor conserved in humans ...

Super-Resolution Mapping of Neuronal Circuitry With an Index-Optimized Clearing Agent
Super-resolution imaging deep inside tissues has been challenging, as it is extremely sensitive to light scattering and spherical aberrations. Here, we report an optimized optical clearing agent for high-resolution fluorescence imaging (SeeDB2).

Age-cumulative effect of REC8 reduction on meiotic chromosome segregation errors in mice
Objective: This study aimed to explore the relationship between cohesin subunit REC8 reduction and meiosis chromosome segregation errors in the ovary. Methods: Rec8+/− mice were generated using CRIPSR/Cas9 gene editing.

HIM-10 is required for kinetochore structure and function on Caenorhabditis elegans holocentric chromosomes. [PDF]
Macromolecular structures called kinetochores attach and move chromosomes within the spindle during chromosome segregation. Using electron microscopy, we identified a structure on the holocentric mitotic and meiotic chromosomes of Caenorhabditis elegans ...

Non-random Mis-segregation of Human Chromosomes
Summary: A common assumption is that human chromosomes carry equal chances of mis-segregation during compromised cell division. Human chromosomes vary in multiple parameters that might generate bias, but technological limitations have precluded a ...

Mad2, Bub3, and Mps1 regulate chromosome segregation and mitotic synchrony in Giardia intestinalis, a binucleate protist lacking an anaphase-promoting complex. [PDF]
The binucleate pathogen Giardia intestinalis is a highly divergent eukaryote with a semiopen mitosis, lacking an anaphase-promoting complex/cyclosome (APC/C) and many of the mitotic checkpoint complex (MCC) proteins.
