Tau acetylation at K331 has limited impact on tau pathology in vivo

open access: yesFEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Specialized interfaces of Smc5/6 control hinge stability and DNA association

open access: yesNature Communications, 2017
Structural Maintenance of Chromosomes (SMC) complexes maintain genome integrity by regulating the segregation of chromosomes. Here, Altet al. describe the structure of the heterodimeric Smc5/6-hinge from fission yeast and define functional features ...

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Centromere protection requires strict mitotic inactivation of the Bloom syndrome helicase complex

open access: yesNature Communications
The BTRR (BLM/TOP3A/RMI1/RMI2) complex resolves DNA replication and recombination intermediates to maintain genome stability. Alongside PICH, they target mitotic DNA intertwinements, known as ultrafine DNA bridges, facilitating chromosome segregation ...

Somatic PMK-1/p38 signaling links environmental stress to germ cell apoptosis and heritable euploidy

open access: yesNature Communications, 2022
Here the authors show that elimination of germ cells carrying damaged genomes is regulated by intestinal stress signalling in nematodes. Failure of the intestinal signalling results in stress-induced aneuploidy indicating that environmental stress ...

Multi-Platform Next-Generation Sequencing of the Domestic Turkey (Meleagris gallopavo): Genome Assembly and Analysis [PDF]

open access: yes, 2010
A synergistic combination of two next-generation sequencing platforms with a detailed comparative BAC physical contig map provided a cost-effective assembly of the genome sequence of the domestic turkey (Meleagris gallopavo).

Entschlüsselung des Mechanismus von RIF1 zur Aufrechterhaltung der DNA-Replikations-assoziierten Genomstabilität

open access: yes, 2021
Timely and accurate genome duplication is essential to maintain genome integrity and cell survival. DNA replication-associated damage is one of the leading causes of genome instability and a precursor for carcinogenesis.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

ATR Activates the S-M Checkpoint during Unperturbed Growth to Ensure Sufficient Replication Prior to Mitotic Onset

open access: yesCell Reports, 2013
Cells must accurately replicate and segregate their DNA once per cell cycle in order to successfully transmit genetic information. During S phase in the presence of agents that cause replication stress, ATR-dependent checkpoints regulate origin firing ...
