Structural and biochemical analysis of the UvrA binding module of the bacterial transcription repair coupling factor Mfd [PDF]

, 2006
The Mfd (mutation frequency decline) protein is responsible for connecting the cellular processes of transcription and DNA repair in bacteria. Mfd, also termed transcription-repair coupling factor (TRCF), recognizes arrested transcription elongation ...

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer

Molecular Oncology, EarlyView.
Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.

RA-risk synovium exhibits DNA damage coupled with impaired DNA repair in fibroblasts

RMD Open
Objectives Understanding the molecular changes in the preclinical synovium is crucial for identifying factors that drive arthritis development. Persistent DNA damage in tissues is known to drive a senescent microenvironment, genomic instability and ...

Epigenetic heterogeneity and plasticity in therapy‐induced tumor states through single‐cell multi‐omics

Molecular Oncology, EarlyView.
Single‐cell multi‐omics reveals epigenetic heterogeneity across therapy‐adaptive tumor states, including quiescent/dormant, drug‐tolerant persister, and EMT‐like phenotypes. By linking regulatory features with state‐associated biomarkers, these approaches inform biomarker‐guided therapeutic strategies for evolving tumors.

Inhibition of cyclin‐dependent kinases 12/13 using CT7439 as a treatment for colorectal cancer with CDK12 upregulation

Molecular Oncology, EarlyView.
The proposed mechanism of action for the CDK12/13 inhibitor and cyclin K degrader, CT7439. CDK12/13 inhibition interrupts transcription elongation, leading to increased DNA damage that results in cell death. This agent is a potentially novel treatment option for patients with colorectal cancer. Created in BioRender. Cyclin‐dependent kinase (CDK) 12 and

Quantification of complex DNA damage by ionising radiation: An experimental and theoretical approach

, 2000
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Ionising radiation potentially produces a broad spectrum of damage in DNA including single and double strand breaks (ssb and dsb) and base damages.

Direct Involvement of Retinoblastoma Family Proteins in DNA Repair by Non-homologous End-Joining.

, 2015
Deficiencies in DNA double-strand break (DSB) repair lead to genetic instability, a recognized cause of cancer initiation and evolution. We report that the retinoblastoma tumor suppressor protein (RB1) is required for DNA DSB repair by canonical non ...

DNA Damage and Repair

, 2020
DNA can be damaged by both environmental factors and normal metabolic processes or replication errors. While some lesions result from single-stranded or double-stranded breaks in the DNA sequence, in most cases, the DNA sequences have been chemically modified.

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

FEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Characterisation of XPD from Sulfolobus acidocaldarius : an iron-sulphur cluster containing DNA repair helicase

, 2007
DNA is constantly damaged by a variety of exogenous and endogenous sources. To maintain the integrity of the genome, different DNA repair mechanisms have evolved, which deal with different kinds of DNA damage.
