Chromosome segregation in lymphocyte hybrids [PDF]
Hereditas, 2009 Chromosome segregation was studied in mouse/human and mouse/mouse T-lymphocyte hybrids, and in mouse/human, mouse/rabbit and mouse/rat B-lymphocyte hybrids. Chromosome loss was not random, it was moderate in mouse/mouse and mouse/rat lymphocyte hybrids, but extensive in mouse/human and mouse/rabbit lymphocyte hybrids.

mBio, 2019 Coordinating chromosome duplication and segregation with cell division is clearly critical for bacterial species with one chromosome. The precise choreography required is even more complex in species with more than one chromosome.

Bactofilin-mediated organization of the ParABS chromosome segregation system in Myxococcus xanthus
Nature Communications, 2017 In bacteria, homologs of actin, tubulin, and intermediate filament proteins often act in concert with bacteria-specific scaffolding proteins to ensure the proper arrangement of cellular components. Among the bacteria-specific factors are the bactofilins,

PRC1‐Mediated H2Aub Loop Formation and Function in Arabidopsis
Advanced Science, EarlyView.In the Arabidopsis genome, H2Aub and H3K27me3 marks do not always co‐localize, and some regions are marked exclusively by H2Aub. By using Capture‐Hi‐C, it is found that H2Aub loops are preferentially established between two H2Aub enriched regions.

Advanced Science, EarlyView.Simulated microgravity induces distinct mitochondrial hyperactivation patterns‐elevated OXPHOS and MMP‐which accelerate meiosis without SAC failure but delays MTOC coalescence, leading to spindle defects and meiotic arrest. Prolonging M‐phase restores MTOC assembly and oocyte maturation.

Bacterial Chromosome Organization and Segregation [PDF]
Cold Spring Harbor Perspectives in Biology, 2010 Bacterial chromosomes are generally approximately 1000 times longer than the cells in which they reside, and concurrent replication, segregation, and transcription/translation of this crowded mass of DNA poses a challenging organizational problem. Recent advances in cell-imaging technology with subdiffraction resolution have revealed that the bacterial

Exotic mitotic mechanisms [PDF]
Open Biology, 2012 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.

Meiotic spindle assembly and chromosome segregation in oocytes
Journal of Cell Biology, 2016 Centrosomes play a key role in organizing the microtubule spindle that separates chromosomes during mitosis. Bennabi et al. review how microtubule spindle formation and chromosomal segregation also occur in oocytes during cell division by meiosis despite

YTHDC1 Is Essential for Postnatal Liver Development and Homeostasis
Advanced Science, EarlyView.This study identifies YTHDC1 as a key regulator of postnatal liver development and disease. Hepatocyte‐specific deletion of Ythdc1 impairs hepatocyte maturation, causing liver injury, contributing to nonalcoholic steatohepatitis and hepatocellular carcinoma.

Cdc14 and PP2A Phosphatases Cooperate to Shape Phosphoproteome Dynamics during Mitotic Exit
Cell Reports, 2019 Summary: Temporal control over protein phosphorylation and dephosphorylation is crucial for accurate chromosome segregation and for completion of the cell division cycle during exit from mitosis. In budding yeast, the Cdc14 phosphatase is thought to be a
