Effect of the GSTM1 genotype on the biomarkers of exposure to polycyclic aromatic hydrocarbons: Meta-analysis

International Journal of Occupational Medicine and Environmental Health, 2017
The role of glutathione S-transferase Mu 1 (GSTM1) in the biomonitoring of polycyclic aromatic hydrocarbons (PAHs) is not clear. Our purpose has been to evaluate the influence of GSTM1 genotypes on 1-hydroxypyrene (1-OHP), deoxyribonucleic acid (DNA ...

MLH1 p.His112Arg Variant Is Associated With Increased Cancer Susceptibility

International Journal of Cancer, EarlyView.
ABSTRACT Lynch syndrome, a prevalent hereditary cancer predisposition, is frequently caused by pathogenic variants in the MutL homolog 1 (MLH1) mismatch repair gene. However, a significant proportion of MLH1 missense variants remain classified as variants of uncertain significance (VUS), creating clinical ambiguity.

Hematological and Genotoxic Effects of Subchronic Oral Exposure to a Mancozeb‐Based Fungicide in Female Mice

Journal of Applied Toxicology, EarlyView.
ABSTRACT The extensive use of pesticides in modern agriculture has raised increasing concerns regarding the potential biological effects of repeated exposure to pesticide residues and commercial formulations. Mancozeb is a widely used ethylene‐bis‐dithiocarbamate fungicide; however, information on its hematological and genotoxic effects following ...

Giemsa versus acridine orange staining in the fish micronucleus assay and validation for use in water quality monitoring [PDF]

, 2011
This study concerns a comparative analysis of the acridineorange and Giemsastaining procedures for the fish erythrocyte micronucleusassay. The goal was to optimize the assay in the context of field watermonitoring. Fish (Carassius carassius) were exposed

Dual Genotoxic and Antigenotoxic Effects of 3‐Benzoylcoumarins in Mammalian Cells

Journal of Applied Toxicology, EarlyView.
ABSTRACT Coumarins are phenolic compounds widely recognized for their diverse pharmacological activities and have attracted increasing attention as potential chemopreventive agents. In the present study, four known 3‐benzoylcoumarin derivatives [(1), (2), (3), and (4)] were evaluated for their cytotoxic, mutagenic, and antigenotoxic effects in Chinese ...

High‐Content Screening Comparison of 1R6F Cigarette Smoke Extract and Selected Heated Tobacco and Electronic Vapour Product Aerosol Extracts in Endothelial and Bronchial Epithelial Cell Models

Journal of Applied Toxicology, EarlyView.
ABSTRACT Cigarettes induce oxidative stress and DNA damage, processes that contribute to cardiovascular and pulmonary disease. High content screening (HCS) is an increasingly valuable tool for comparative toxicology because it enables simultaneous quantification of multiple mechanistic endpoints at single‐cell resolution. In this study, HCS was used to

Cytotoxic and Genotoxic Effects in Buccal Cells of Sandstone Quarry Workers

Journal of Applied Toxicology, EarlyView.
ABSTRACT Mineral extraction poses significant occupational health risks, particularly from respirable crystalline silica exposure. Sandstone quarrying generates substantial dust, yet evidence of its genotoxic effects remains limited. This study investigated cytogenotoxic damage in sandstone quarry workers from southern Brazil using the buccal ...

Evaluation of Genotoxicity by Micronucleus Assay in vitro and by Allium cepa Test in vivo

Bio-Protocol, 2019
The in vitro and in vivo genotoxicity of new metallodrugs either as Small Bioactive Molecules (SBAMs) or Conjugates of Metals with Drugs (CoMeDs) is evaluated by the micronucleus test and the Allium cepa assay, respectively.

Ionic liquids: structure–toxicity relationships, predictive toxicology, and sustainable design

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract Ionic liquids (ILs) have often been described as green alternatives to conventional solvents because of their negligible vapor pressure and highly tunable properties. However, low volatility does not necessarily translate into environmental safety, as their biological and ecological effects are strongly influenced by molecular structure.
