Self‐Assembling Hybrid Hydrogel Reprograms the Stromal Vascular Fraction to Treat Osteoarthritis

Advanced Science, EarlyView.
This study presents a bioinspired injectable hydrogel that enhances the therapeutic potential of stem cell‐rich stromal vascular fraction for treating osteoarthritis. By reprogramming cell behavior through epigenetic modulation, the hydrogel promotes cartilage regeneration and reduces joint damage in a rat model, offering a promising new approach for ...

DNA break site at fragile subtelomeres determines probability and mechanism of antigenic variation in African trypanosomes.

PLoS Pathogens, 2013
Antigenic variation in African trypanosomes requires monoallelic transcription and switching of variant surface glycoprotein (VSG) genes. The transcribed VSG, always flanked by '70 bp'-repeats and telomeric-repeats, is either replaced through DNA double ...

Human Herpesvirus-6 U14 Induces Cell-Cycle Arrest in G2/M Phase by Associating with a Cellular Protein, EDD. [PDF]

PLoS ONE, 2015
The human herpesvirus-6 (HHV-6) infection induces cell-cycle arrest. In this study, we found that the HHV-6-encoded U14 protein induced cell-cycle arrest at G2/M phase via an association with the cellular protein EDD, a mediator of DNA-damage signal ...

Double-strand break repair and homologous recombination in Schizosaccharomyces pombe [PDF]

, 2006
In recent years our understanding of double strand break repair and homologous recombination in Schizosaccharomyces pombe has increased significantly, and the identification of novel pathways and genes with homologues in higher eukaryotes has increased ...

Cdk1 Protein-mediated Phosphorylation of Receptor-associated Protein 80 (RAP80) Serine 677 Modulates DNA Damage-induced G2/M Checkpoint and Cell Survival [PDF]

Journal of Biological Chemistry, 2013
Post-translational phosphorylation plays critical roles in the assembly of signaling and repair proteins in the DNA damage response pathway. RAP80, a component of the BRCA1-A complex, is crucial in cell cycle checkpoint activation and DNA damage repair. However, its molecular mechanism is unclear.

DMAP1 Deficiency Suppresses Lung Cancer Progression by Destabilizing Replication Fork and Activating IFN Signaling‐Mediated Anti‐tumor Immunity

Advanced Science, EarlyView.
Lung cancer remains the leading cause of cancer‐related death. We investigated the role of the epigenetic regulator DMAP1 in NSCLC and found that its loss induces replication stress and DNA damage. This in turn activates type I IFN signaling via the cGAS–STING pathway and transcriptional ISG de‐repression, enhancing anti‐tumor immune responses ...

BET Bromodomain Inhibition Synergizes with PARP Inhibitor in Epithelial Ovarian Cancer

Cell Reports, 2017
Summary: PARP inhibition is known to be an effective clinical strategy in BRCA mutant cancers, but PARP inhibition has not been applied to BRCA-proficient tumors.

RNase H enables efficient repair of R-loop induced DNA damage. [PDF]

, 2016
R-loops, three-stranded structures that form when transcripts hybridize to chromosomal DNA, are potent agents of genome instability. This instability has been explained by the ability of R-loops to induce DNA damage. Here, we show that persistent R-loops

Caffeine Abolishes the Mammalian G2/M DNA Damage Checkpoint by Inhibiting Ataxia-Telangiectasia-mutated Kinase Activity [PDF]

Journal of Biological Chemistry, 2000
Recent evidence indicates that arrest of mammalian cells at the G(2)/M checkpoint involves inactivation and translocation of Cdc25C, which is mediated by phosphorylation of Cdc25C on serine 216. Data obtained with a phospho-specific antibody against serine 216 suggest that activation of the DNA damage checkpoint is accompanied by an increase in serine ...
