Absence of genotoxic effects of the chalcone (E)-1-(2-hydroxyphenyl)-3-(4-methylphenyl)-prop-2-en-1-one) and its potential chemoprevention against DNA damage using in vitro and in vivo assays. [PDF]

PLoS ONE, 2017
The chalcone (E)-1-(2-hydroxyphenyl)-3-(4-methylphenyl)-prop-2-en-1-one), or 2HMC, displays antileishmanial, antimalarial, and antioxidant activities. The aim of this study was to investigate the cytotoxic, genotoxic, mutagenic, and protective effects of

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 ...

CDK4/6 inhibitor-induced bone marrow micronuclei might be caused by cell cycle arrest during erythropoiesis

Genes and Environment
Background A micronucleus test is generally used to evaluate the genotoxic potential of chemicals. Exaggerated erythropoiesis, as occurs following bleeding, may induce an unexpected increase in micronucleus frequency.

CYTOKINESIS-BLOCK MICRONUCLEUS ASSAY IN HUMAN GLIOMA CELLS EXPOSED TO RADIATION

Image Analysis and Stereology, 2011
Biological tests are efficient in reflecting the biological influences of several types of generally harmful exposures. The micronucleus assay is widely used in genotoxicity studies or studies on genomic damage in general.

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
