DNA Damage, Mutagenesis, and DNA Repair [PDF]

Journal of Nucleic Acids, 2010
This special issue of the Journal of Nucleic Acids is dedicated to DNA damage and two important biological consequences provoked by such damage: lesion repair and lesion-induced mutagenesis. These phenomena have attracted broad interest among a large community of scientists that cross disciplines from mathematics, physics, chemistry, and biology to ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

DNA Repair by Reversal of DNA Damage [PDF]

Cold Spring Harbor Perspectives in Biology, 2013
Endogenous and exogenous factors constantly challenge cellular DNA, generating cytotoxic and/or mutagenic DNA adducts. As a result, organisms have evolved different mechanisms to defend against the deleterious effects of DNA damage. Among these diverse repair pathways, direct DNA-repair systems provide cells with simple yet efficient solutions to ...

Regulation of nucleotide excision repair by UV-DDB: prioritization of damage recognition to internucleosomal DNA [PDF]

, 2011
How tightly packed chromatin is thoroughly inspected for DNA damage is one of the fundamental unanswered questions in biology. In particular, the effective excision of carcinogenic lesions caused by the ultraviolet (UV) radiation of sunlight depends on ...

DNA packaging and polycation length determine DNA susceptibility to free radical damage in condensed DNA [PDF]

, 2023
In nature, DNA exists primarily in a highly compacted form. The compaction of DNA in vivo is mediated by cationic proteins; histone in somatic nuclei and protamines in sperm chromatin.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

The Influence of Single, Tandem, and Clustered DNA Damage on the Electronic Properties of the Double Helix: A Theoretical Study

Molecules, 2020
Oxidatively generated damage to DNA frequently appears in the human genome as the effect of aerobic metabolism or as the result of exposure to exogenous oxidizing agents, such as ionization radiation.

Investigating transcription factor dynamics in health and disease using FRAP

FEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Specialized interfaces of Smc5/6 control hinge stability and DNA association

Nature Communications, 2017
Structural Maintenance of Chromosomes (SMC) complexes maintain genome integrity by regulating the segregation of chromosomes. Here, Altet al. describe the structure of the heterodimeric Smc5/6-hinge from fission yeast and define functional features ...
