Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

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

open access: yes, 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 ...

Base Excision Repair Gene Polymorphisms and Wilms Tumor Susceptibility

open access: yesEBioMedicine, 2018
Base excision repair (BER) is the main mechanism to repair endogenous DNA lesions caused by reactive oxygen species. BER deficiency is linked with cancer susceptibility and premature aging.

Base Excision Repair Variants in Cancer [PDF]

open access: yes, 2017
Base excision repair (BER) is a key genome maintenance pathway that removes endogenously damaged DNA bases that arise in cells at very high levels on a daily basis. Failure to remove these damaged DNA bases leads to increased levels of mutagenesis and chromosomal instability, which have the potential to drive carcinogenesis.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Transcription-coupled nucleotide excision repair and its regulation by the DNA damage checkpoint [PDF]

open access: yes, 2009
Elaborate DNA repair mechanisms have evolved, allowing cells to repair damages in their genomes. Nucleotide excision repair (NER) removes a variety of helix-distorting lesions, including those caused by ultraviolet (UV) irradiation.

The relationship between DNA damage and repair and the occurrence and development of disease

open access: yesFrontiers in Genetics
DNA damage can lead to the development of diseases such as tumors. To counteract this, organisms have evolved various repair mechanisms targeting different types of damage.

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

open access: yesFEBS 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 ...

Transcriptional coupling (Mfd) and DNA damage scanning (DisA) coordinate excision repair events for efficient Bacillus subtilis spore outgrowth

open access: yesMicrobiologyOpen, 2018
The absence of base excision repair (BER) proteins involved in processing ROS‐promoted genetic insults activates a DNA damage scanning (DisA)‐dependent checkpoint event in outgrowing Bacillus subtilis spores.

Structural basis for APE1 processing DNA damage in the nucleosome

open access: yesNature Communications, 2022
AP endonuclease 1 (APE1) processes genomic AP sites during base excision repair. Here, the authors determine the structural mechanism used by APE1 to process nucleosomal AP sites, providing new insight into DNA repair in chromatin.
