Histone variant H2A.Z cooperates with EBNA1 to maintain Epstein-Barr virus latent epigenome

open access: yesmBio
Chromatin structure plays a central role in the regulation of Epstein-Barr virus (EBV) latency. The histone variant H2A.Z.1 has been implicated in chromatin structures associated with the initiation of transcription and DNA replication.

Suppression of Nucleotide Metabolism Underlies the Establishment and Maintenance of Oncogene-Induced Senescence

open access: yesCell Reports, 2013
Oncogene-induced senescence is characterized by a stable cell growth arrest, thus providing a tumor suppression mechanism. However, the underlying mechanisms for this phenomenon remain unknown.

The three-dimensional structure of Epstein-Barr virus genome varies by latency type and is regulated by PARP1 enzymatic activity

open access: yesNature Communications, 2022
Genome folding in the nucleus plays an important role in regulating gene expression. Here the authors show that 3D genome architecture also plays an important role for gene expression adaptability for the Epstein-Barr Virus (EBV), a virus that is ...

Neuropeptide Y—Graphene Oxide Complexes Inhibit Amygdala NPY‐Receptor Expressing Glutamatergic Pathways and Selectively Remove Aversive Memory In Vivo

open access: yesAdvanced Science, EarlyView.
A graphene oxide nanocarrier presents neuropeptide Y specifically to NPY receptor‐expressing pathways in the amygdala, whose activation selectively suppresses aversive memory formation, without modulating anxiety responses. This circuit‐restricted drug release strategy may impact future design of neuropsychiatric therapies with limited off‐target ...

Bioadhesive‐Integrated 3D‐Printed Multilayer Scaffolds Secure a Mechanically‐Stable Osteoimmune Niche for Enhanced Bone Augmentation

open access: yesAdvanced Science, EarlyView.
A 3D‑printed multilayer adhesive scaffold, firmly anchored to bone defects by simple finger pressing, suppresses micromotion and secures mechanical stability of the osteogenic niche. This stabilization likely contributes to the enhanced bone augmentation by fostering a pro‑regenerative mechano‐immune profile—characterized by M2‑like macrophage ...

SWI/SNF catalytic subunits’ switch drives resistance to EZH2 inhibitors in ARID1A-mutated cells

open access: yesNature Communications, 2018
The mechanism of resistance to EZH2 inhibitors in cancers with inactivating SWI/SNF mutations is unknown. Here, the authors demonstrate that the switch of the SWI/SNF catalytic subunits from SMARCA4 to SMARCA2 drives resistance to EZH2 inhibitors in ...

Decitabine disrupts EBV genomic epiallele DNA methylation patterns around CTCF binding sites to increase chromatin accessibility and lytic transcription in gastric cancer

open access: yesmBio, 2023
Epstein-Barr virus (EBV) is associated with 10% of human gastric carcinomas, which are distinguished by a CpG island methylator phenotype. In gastric carcinoma tumors and cell lines, the EBV genome also exhibits a high degree of 5-methyl cytosine (5mC ...

Unravelling the Distinct Phenotype and Mechanosensitive Properties of Different Tendon Cell Populations

open access: yesAdvanced Science, EarlyView.
Tendon interfascicular and fascicular matrix cells are isolated and cultured, revealing distinct phenotypes and mechanosensitive responses. Interfascicular matrix cells exhibit marked stiffness‐dependent phenotypic plasticity, whereas fascicular matrix cells remain comparatively stable.

Clonal dynamics shaped by diverse drug-tolerant persister states in melanoma resistance

open access: yesMolecular Cancer
Background Most advanced melanomas initially respond to targeted therapy but eventually relapse. Increasing evidence suggests that drug-tolerant persister cells can adopt a reversible drug-refractory state and represent a key driver of therapeutic ...

Differences in the evolution of the ischemic penumbra in stroke-prone spontaneously hypertensive and Wistar-Kyoto rats [PDF]

open access: yes, 2009
<p><b>Background and Purpose:</b> Stroke-prone spontaneously hypertensive rats (SHRSP) are a highly pertinent stroke model with increased sensitivity to focal ischemia compared with the normotensive reference strain (Wistar-Kyoto rats ...
