Urinary DNA adductomics – A novel approach for exposomics

open access: yesEnvironment International, 2018
The exposome is a concept that encompasses the totality of internal and external environmental exposures, from conception onwards. Evaluation of the exposome, across the lifecourse represents a significant challenge, e.g., methods/technology may simply ...

Dissociation Dynamics of XPC-RAD23B from Damaged DNA Is a Determining Factor of NER Efficiency. [PDF]

open access: yesPLoS ONE, 2016
XPC-RAD23B (XPC) plays a critical role in human nucleotide excision repair (hNER) as this complex recognizes DNA adducts to initiate NER. To determine the mutagenic potential of structurally different bulky DNA damages, various studies have been ...

In vitro DNA/RNA Adductomics to Confirm DNA Damage Caused by Benzo[a]pyrene in the Hep G2 Cell Line

open access: yesFrontiers in Chemistry, 2019
In the development of new chemical substances, genetic toxicity evaluations are a high priority for safety risk management. Evaluation of the possibility of compound carcinogenicity with accuracy and at reasonable cost in the early stages of development ...

The Response of the Replication Apparatus to Leading Template Strand Blocks

open access: yesCells, 2023
Duplication of the genome requires the replication apparatus to overcome a variety of impediments, including covalent DNA adducts, the most challenging of which is on the leading template strand.

Alcohol, Aldehydes, Adducts and Airways

open access: yesBiomolecules, 2015
Drinking alcohol and smoking cigarettes results in the formation of reactive aldehydes in the lung, which are capable of forming adducts with several proteins and DNA.

Recent Studies on DNA Adducts Resulting from Human Exposure to Tobacco Smoke

open access: yesToxics, 2019
DNA adducts are believed to play a central role in the induction of cancer in cigarette smokers and are proposed as being potential biomarkers of cancer risk. We have summarized research conducted since 2012 on DNA adduct formation in smokers.

Sperm DNA oxidative damage and DNA adducts [PDF]

open access: yesMutation Research/Genetic Toxicology and Environmental Mutagenesis, 2015
The objective of this study was to investigate DNA damage and adducts in sperm from coke oven workers who have been exposed to polycyclic aromatic hydrocarbons. A longitudinal study was conducted with repeated measurements during spermatogenesis. Coke-oven workers (n=112) from a coke-oven plant served the PAH-exposed group, while administrators and ...

Formation and Repair of Tobacco Carcinogen-Derived Bulky DNA Adducts

open access: yesJournal of Nucleic Acids, 2010
DNA adducts play a central role in chemical carcinogenesis. The analysis of formation and repair of smoking-related DNA adducts remains particularly challenging as both smokers and nonsmokers exposed to smoke are repetitively under attack from complex ...

The role of reactive oxygen species (ROS) and cytochrome P-450 2E1 in the generation of carcinogenic etheno-DNA adducts

open access: yesRedox Biology, 2014
Exocyclic etheno-DNA adducts are mutagenic and carcinogenic and are formed by the reaction of lipidperoxidation (LPO) products such as 4-hydoxynonenal or malondialdehyde with DNA bases.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
