Biological contexts for DNA charge transport chemistry [PDF]

open access: yes, 2008
Many experiments have now shown that double helical DNA can serve as a conduit for efficient charge transport (CT) reactions over long distances in vitro. These results prompt the consideration of biological roles for DNA-mediated CT.

Antibiotic Remodeling of the Gut Microbiota Impairs Host Resistance to Secondary Infection

open access: yesiMetaMed, EarlyView.
Gut microbial dynamics induced by four antibiotics, revealed distinct taxonomic and functional shifts. Vancomycin‐perturbed bacteriomes were proven to promote pathogen resistance to antibiotic treatment. Metronidazole‐treated mice showed pronounced Salmonella translocation to hepatic tissue, and altered Enterococcus avium populations modulated host ...

Nei-like 1 (NEIL1) excises 5-carboxylcytosine directly and stimulates TDG-mediated 5-formyl and 5-carboxylcytosine excision [PDF]

open access: yes, 2017
Thymine DNA glycosylase (TDG) and Nei-like 1 (NEIL1) have both been implicated in the base excision repair step of active DNA demethylation. The robust glycosylase activity of TDG on DNA substrates containing 5-formylcytosine (5fC) or 5-carboxylcytosine (

Epigenetic Regulation in the Pathogenesis of Renal Inflammation: Insights and Therapeutic Potentials

open access: yesiNew Medicine, EarlyView.
ABSTRACT Renal inflammation is a common pathological process in various kidney diseases, often initiated by factors such as toxins, ischemia, or autoimmune reactions. This inflammatory response can result in structural damage and a rapid decline in renal function.

Pa-AGOG, the founding member of a new family of archaeal 8-oxoguanine DNA-glycosylases [PDF]

open access: yes, 2017
Oxidative damage represents a major threat to genomic stability, as the major product of DNA oxidation, 8-oxoguanine (GO), frequently mispairs with adenine during replication.

Monitoring regulation of DNA repair activities of cultured cells in-gel using the comet assay [PDF]

open access: yes, 2014
Base excision repair (BER) is the predominant cellular mechanism by which human cells repair DNA base damage, sites of base loss and DNA single strand breaks of various complexity, that are generated in their thousands in every human cell per day as a ...

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

SUVH1, a Su(var)3-9 family member, promotes the expression of genes targeted by DNA methylation. [PDF]

open access: yes, 2015
Transposable elements are found throughout the genomes of all organisms. Repressive marks such as DNA methylation and histone H3 lysine 9 (H3K9) methylation silence these elements and maintain genome integrity.

Iron Physiology and Its Impact on Atopic Diseases: An EAACI Taskforce Report

open access: yesAllergy, EarlyView.
ABSTRACT Iron is essential for oxygen transport, energy metabolism, and immune regulation. Yet iron deficiency is the most common micronutrient disorder across all age groups, affecting nearly one quarter of the global population. Iron deficiency triggers nutritional immunity, a host defense mechanism that withholds and redistributes iron, contributing

An AP endonuclease functions in active DNA demethylation and gene imprinting in Arabidopsis [corrected]. [PDF]

open access: yesPLoS Genetics, 2015
Active DNA demethylation in plants occurs through base excision repair, beginning with removal of methylated cytosine by the ROS1/DME subfamily of 5-methylcytosine DNA glycosylases.
