The immunological consequences of radiation-induced DNA damage.
(WILEY, 2019-04-01)
Historically, our understanding of the cytotoxicity of radiation has centred on tumour cell-autonomous mechanisms of cell death. Here, tumour cell death occurs when a threshold number of radiation-induced non-reparable ...
WDR5, BRCA1, and BARD1 Co-regulate the DNA Damage Response and Modulate the Mesenchymal-to-Epithelial Transition during Early Reprogramming.
(CELL PRESS, 2019-04-09)
Differentiated cells are epigenetically stable, but can be reprogrammed to pluripotency by expression of the OSKM transcription factors. Despite significant effort, relatively little is known about the cellular requirements ...
A comprehensive model for the proliferation-quiescence decision in response to endogenous DNA damage in human cells.
(NATL ACAD SCIENCES, 2018-03-06)
Human cells that suffer mild DNA damage can enter a reversible state of growth arrest known as quiescence. This decision to temporarily exit the cell cycle is essential to prevent the propagation of mutations, and most ...
Quantitative Cell Cycle Analysis Based on an Endogenous All-in-One Reporter for Cell Tracking and Classification.
(CELL PRESS, 2017-05-30)
Cell cycle kinetics are crucial to cell fate decisions. Although live imaging has provided extensive insights into this relationship at the single-cell level, the limited number of fluorescent markers that can be used in ...
ATMIN Is a Tumor Suppressor Gene in Lung Adenocarcinoma.
(AMER ASSOC CANCER RESEARCH, 2019-10-15)
Tumor cells proliferate rapidly and thus are frequently subjected to replication stress and the risk of incomplete duplication of the genome. Fragile sites are replicated late, making them more vulnerable to damage when ...
HSP90 inhibition sensitizes head and neck cancer to platin-based chemoradiotherapy by modulation of the DNA damage response resulting in chromosomal fragmentation.
(BIOMED CENTRAL LTD, 2017-01-31)
BACKGROUND: Concurrent cisplatin radiotherapy (CCRT) is a current standard-of-care for locally advanced head and neck squamous cell carcinoma (HNSCC). However, CCRT is frequently ineffective in patients with advanced ...
Radiosensitization by the ATR Inhibitor AZD6738 through Generation of Acentric Micronuclei.
(AMER ASSOC CANCER RESEARCH, 2017-01-01)
AZD6738 is an orally active ATR inhibitor (ATRi) currently in phase I clinical trials. We found in vitro growth inhibitory activity of this ATRi in a panel of human cancer cell lines. We demonstrated radiosensitization by ...
Removal of H2A.Z by INO80 promotes homologous recombination.
(WILEY, 2015-08-01)
The mammalian INO80 remodelling complex facilitates homologous recombination (HR), but the mechanism by which it does this is unclear. Budding yeast INO80 can remove H2A.Z/H2B dimers from chromatin and replace them with ...
DNA damage during S-phase mediates the proliferation-quiescence decision in the subsequent G1 via p21 expression.
(NATURE PUBLISHING GROUP, 2017-03-20)
Following DNA damage caused by exogenous sources, such as ionizing radiation, the tumour suppressor p53 mediates cell cycle arrest via expression of the CDK inhibitor, p21. However, the role of p21 in maintaining genomic ...
Active mRNA degradation by EXD2 nuclease elicits recovery of transcription after genotoxic stress.
(NATURE PORTFOLIO, 2023-01-20)
The transcriptional response to genotoxic stress involves gene expression arrest, followed by recovery of mRNA synthesis (RRS) after DNA repair. We find that the lack of the EXD2 nuclease impairs RRS and decreases cell ...
