A Cohesin-Based Partitioning Mechanism Revealed upon Transcriptional Inactivation of Centromere.

PLoS Genetics, 2016
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 ...

ZSL Orchestrates Synaptonemal Complex Assembly as a Central Region Scaffold to Ensure Synapsis Fidelity and Crossover Control in Polyploid Meiosis

Advanced Science, EarlyView.
A central molecular adaptor, ZSL, is identified that links transverse filaments ZYP1 to central element SCEP1/2 to drive synaptonemal complex assembly in Brassica napus. Loss of ZSL abolishes synaptonemal complex formation, disrupts meiotic chromosome segregation, and markedly increases crossovers, providing mechanistic insight into meiotic fidelity ...

In Vivo Imaging of the Segregation of the 2 Chromosomes and the Cell Division Proteins of Rhodobacter sphaeroides Reveals an Unexpected Role for MipZ

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.

Species Dependent Toxicity Comparison Outcome

Advanced Science, EarlyView.
By quantitatively assessing and comparing toxicity responses across different animal species and material compositions, our data reveal that toxicity rankings among different materials may be reversed across species. ABSTRACT Toxicity comparison plays a crucial role in material selection across diverse application fields.

p53 Prohibits Propagation of Chromosome Segregation Errors that Produce Structural Aneuploidies

Cell Reports, 2017
Summary: The presence of an abnormal karyotype has been shown to be profoundly detrimental at the cellular and organismal levels but is an overt hallmark of cancer.

Multi‐Omics Insights Into the Mechanisms of Early Muscle Fiber Difference and Transformation Between Lean‐Type and Chinese Indigenous Pigs

Advanced Science, EarlyView.
Multi‐omics analyses uncover breed‐specific cis‐regulatory landscapes and higher‐order chromatin architectural differences that underlie early postnatal muscle fiber divergence in pigs. A super‐enhancer upstream of PPP3CB recruits MEF2C to activate PPP3CB transcription, while the PPP3CB–MEF2C positive feedback loop promotes oxidative muscle fiber ...

Loop-extruders alter bacterial chromosome topology to direct entropic forces for segregation

Nature Communications
Entropic forces have been argued to drive bacterial chromosome segregation during replication. In many bacterial species, however, specifically evolved mechanisms, such as loop-extruding SMC complexes and the ParABS origin segregation system, contribute ...

Histone Marks Direct Chromosome Segregation [PDF]

Cell, 2015
Germline stem cells divide asymmetrically, producing a self-renewing stem cell and a differentiating progenitor. Xie et al. now show that this depends on two asymmetric events that together partition a genome copy, carrying the old histones to the stem cell daughter and a copy with new, unmarked histones to the differentiating daughter.
