Effects of dietary fish oil on the depletion of carcinogenic PAH-DNA adduct levels in the liver of B6C3F1 mouse. [PDF]

open access: yesPLoS ONE, 2011
Many carcinogenic polycyclic aromatic hydrocarbons (PAHs) and their metabolites can bind covalently to DNA. Carcinogen-DNA adducts may lead to mutations in critical genes, eventually leading to cancer.

Cryo-EM structure of TFIIH/Rad4–Rad23–Rad33 in damaged DNA opening in nucleotide excision repair

open access: yesNature Communications, 2021
The conserved eukaryotic nucleotide excision repair (NER) pathway protects the genome from a wide variety of environmentally induced DNA lesions. Here, the authors provide insights into how NER is initiated on lesions by determining the cryo-EM structure

Interactions between exposure to environmental polycyclic aromatic hydrocarbons and DNA repair gene polymorphisms on bulky DNA adducts in human sperm. [PDF]

open access: yesPLoS ONE, 2010
BACKGROUND: Nucleotide excision repair (NER) and base excision repair (BER) are the primary mechanisms for repair of bulky adducts caused by chemical agents, such as PAHs.

Mass spectrometric profiling of DNA adducts in the human stomach associated with damage from environmental factors

open access: yesGenes and Environment, 2021
Background A comprehensive understanding of DNA adducts, one of the most plausible origins of cancer mutations, is still elusive, especially in human tissues in clinical settings.

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 ...

Pembentukan 8-OHdG Dari Zat Toksik Pemicu Radikal Bebas

open access: yesPharmaceutical Sciences and Research, 2015
This study was conducted to observe the profile of DNA Adduct (8-OHdG) formation as DNA damage indicators, by using calf thymus DNA incubated with toxic and carcinogenic compounds. The compounds which could trigger free radicals in this research were PAH(

DNA Damage and the Gut Microbiome: From Mechanisms to Disease Outcomes

open access: yesDNA, 2023
Both the number of cells and the collective genome of the gut microbiota outnumber their mammalian hosts, and the metabolic and physiological interactions of the gut microbiota with the host have not yet been fully characterized.

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 ...
