Evaluation of DNA adduct damage using G-quadruplex-based DNAzyme [PDF]

open access: yesBioactive Materials, 2023
Toxicity assessment is a major problem in pharmaceutical candidates and industry chemicals development. However, due to the lack of practical analytical methods for DNA adduct analysis, the safety evaluation of drug and industry chemicals was severely ...

Protective Effects of Myricetin on Benzo[a]pyrene-Induced 8-Hydroxy-2′-Deoxyguanosine and BPDE-DNA Adduct [PDF]

open access: yesAntioxidants, 2020
Benzo[a]pyrene (B[a]P), a group 1 carcinogen, induces mutagenic DNA adducts. Myricetin is present in many natural foods with diverse biological activities, such as anti-oxidative and anti-cancer activities.

Modulation of benzo[a]pyrene–DNA adduct formation by CYP1 inducer and inhibitor [PDF]

open access: yesGenes and Environment, 2017
Benzo[a]pyrene (BaP) is a well-studied pro-carcinogen that is metabolically activated by cytochrome P450 enzymes. Cytochrome P4501A1 (CYP1A1) has been considered to play a central role in the activation step, which is essential for the formation of DNA ...

DNA adducts-chemical addons

open access: yesJournal of Pharmacy and Bioallied Sciences, 2015
DNA adduct is a piece of DNA covalently bond to a chemical (safrole, benzopyrenediol epoxide, acetaldehyde). This process could be the start of a cancerous cell. When a chemical binds to DNA, it gets damaged resulting in abnormal replication.

Translocation of benzo(a)pyrene reactive metabolites across human mammary epithelial cell membranes. [PDF]

open access: yesPLoS ONE
DNA adducts from benzo(a)pyrene (BaP) and other polycyclic aromatic hydrocarbons (PAH) are related to tumor initiation in many tissues including mammary epithelia.

Development and application of an LC-MS/MS method for urinary DNA adduct profiling in residents of environmentally vulnerable areas

open access: goldEcotoxicology and Environmental Safety
DNA adducts, formed by the covalent binding of reactive electrophiles to DNA, serve as biomarkers of genotoxic exposure and early biological effects. However, non-invasive, high-throughput biomonitoring methods remain underdeveloped. This study developed

Current and Future Methodology for Quantitation and Site-Specific Mapping the Location of DNA Adducts

open access: yesToxics, 2022
Formation of DNA adducts is a key event for a genotoxic mode of action, and their presence is often used as a surrogate for mutation and increased cancer risk.
