A Prion‐Like Domain in EBV EBNA1 Promotes Phase Separation and Enables SRRM1 Splicing

Advanced Science, EarlyView.
This study discoveries that EBV EBNA1 behaves as a prion‐like protein, verified using cell‐based assays and the Saccharomyces cerevisiae Sup35p prion identification system. The prion‐like domain of EBNA1 drives liquid–liquid phase separation. EBNA1 interacts with the splicing factor SRSF1 to regulate the expression of the SRRM1 splicing isoforms ...

Radiation Exposure Induced Blood–Brain Barrier Injury via Mitochondria‐Mediated Sterile Inflammation

Advanced Science, EarlyView.
This work describes a blood–brain barrier (BBB) microphysiological system (MPS) to explore the responses of BBB to radiation exposure. Following radiation exposure, obvious BBB comprise and brain endothelial injuries are detected. Mechanism study shows radiation induced significant sterile inflammation via mitochondrial dysfunction and cGAS‐STING ...

Cell-Cycle Kinases Coordinate the Resolution of Recombination Intermediates with Chromosome Segregation

Cell Reports, 2013
Homologous recombination leads to the formation of DNA joint molecules (JMs) that must be resolved to allow chromosome segregation, but how resolution is temporally coupled with chromosome segregation is unknown.

Structural Variations Associated with Adaptation and Coat Color in Qinghai‐Tibetan Plateau Cattle

Advanced Science, EarlyView.
This study reveals the landscape of structural variants in Qinghai‐Tibetan Plateau cattle through long‐read sequencing. Discoveries include metabolic and oxygen‐regulation gene variants, along with a 2‐Mb KIT‐containing inversion and translocations responsible for cattle gray coat. These findings highlight the significant role of structural variants in

A companion to the preclinical common data elements for rodent genetic epilepsy models. A report of the TASK3‐WG1B: Paediatric and genetic models working group of the ILAE/AES joint translational TASK force

Epilepsia Open, EarlyView., 2022
Abstract Rodent models of epilepsy remain the cornerstone of research into the mechanisms underlying genetic epilepsy. Reproducibility of experiments using these rodent models, occurring across a diversity of laboratories and commercial vendors, remains an issue impacting the cost‐effectiveness and scientific rigor of the studies performed.

Segregating Chromosomes in the Mammalian Oocyte [PDF]

Current Biology, 2018
Chromosome segregation errors in human oocytes lead to aneuploid embryos that cause infertility and birth defects. Here we provide an overview of the chromosome-segregation process in the mammalian oocyte, highlighting mechanistic differences between oocytes and somatic cells that render oocytes so prone to segregation error.

MatP regulates the coordinated action of topoisomerase IV and MukBEF in chromosome segregation

Nature Communications, 2016
The Escherichia coli SMC complex, MukBEF, forms clusters of molecules that interact with the decatenase topisomerase IV and which are normally associated with the chromosome replication origin region (ori).

Antagonistic Ghd7‐OsNAC42 Complexes Modulate Carbon and Nitrogen Metabolism to Achieves Superior Quality and High Yield in Rice

Advanced Science, EarlyView.
The complex centered on Ghd7 binds to numerous carbon and nitrogen metabolism genes on the genome through the corresponding motifs and transactivates the transcriptional expression of these carbon and nitrogen metabolism genes. With the assistance of OsNAC42 and other unknown Ghd7‐interacting proteins, this complex can regulate different metabolic ...

Resolving Chromosome Segregation in Bacteria

Microbial Physiology, 2006
Bacterial chromosomes are evenly distributed between daughter cells, however no equivalent eukaryotic mitotic apparatus has been identified yet. Nevertheless, an advance in our understanding of the dynamics of the bacterial chromosome has been accomplished in recent years by adopting fluorescence microscopy techniques to visualize living bacterial ...
