Inhibition of MRN activity by a telomere protein motif

open access: yesNature Communications, 2021
Telomeres suppress the DNA damage response at chromosome ends. Here the authors show that in budding yeast the activity of the MRX complex in DNA repair and DNA damage signaling is inhibited by telomeric protein Rif2 via a short motif at the N-terminus.

Mind the replication gap

open access: yesRoyal Society Open Science, 2021
Unlike bacteria, mammalian cells need to complete DNA replication before segregating their chromosomes for the maintenance of genome integrity. Thus, cells have evolved efficient pathways to restore stalled and/or collapsed replication forks during S ...

Stability of non-localized responses for damaging materials [PDF]

open access: yesVietnam Journal of Mechanics, 2008
This work is devoted to the analysis of the stability of the homogeneous states of a bar made of a brittle strain softening material submitted to a tensile loading. We distinguish two types of damage models: local damage models and gradient damage models. We show that a local damage model necessarily leads to the unstability of the homogeneous response

Vibration and buckling of open TWBs with local weakening [PDF]

open access: yes, 2017
Free vibration and Ljapounov stability of compressed open thin-walled beams with a cross-section reduction are studied by a in-house finite differences numerical code, based on a refined direct beam model and allowing for investigating elastic stability ...

A nucleotide resolution map of Top2-linked DNA breaks in the yeast and human genome

open access: yesNature Communications, 2019
Topoisomerase 2 (Top2) is known to resolve DNA topological stress through double strand breaks (DSBs), yet Top2 inhibition has been reported to result in a significant amount of single-strand breaks (SSBs).

Allocation Rules and the Stability of Mass Tort Class Actions [PDF]

open access: yes, 2018
This paper studies the effects of allocation rules on the stability of mass tort class actions. I analyze a two-stage model in which a defendant faces multiple plaintiffs with heterogeneous damage claims.

Ensuring the Stability of the Genome: DNA Damage Checkpoints [PDF]

open access: yesThe Scientific World JOURNAL, 2001
The cellular response to DNA damage is vital for the cell s ability to maintain genomic integrity. Checkpoint signalling pathways, which induce a cell cycle arrest in response to DNA damage, are an essential component of this process. This is reflected by the functional conservation of these pathways in all eukaryotes from yeast to mammalian cells ...

PLK1 facilitates chromosome biorientation by suppressing centromere disintegration driven by BLM-mediated unwinding and spindle pulling

open access: yesNature Communications, 2019
The kinase PLK1 has important roles during cell division, including mitotic entry and bipolar spindle formation. Here, the authors show that PLK1 also functions in centromere protection, with loss leading to DNA unwinding by Bloom’s syndrome helicase and

Prophase-Specific Perinuclear Actin Coordinates Centrosome Separation and Positioning to Ensure Accurate Chromosome Segregation

open access: yesCell Reports, 2020
Summary: Centrosome separation in late G2/ early prophase requires precise spatial coordination that is determined by a balance of forces promoting and antagonizing separation. The major effector of centrosome separation is the kinesin Eg5.
