Mitotic clustering of pulverized chromosomes from micronuclei [PDF]

open access: yes, 2023
Complex genome rearrangements can be generated by the catastrophic pulverization of missegregated chromosomes trapped within micronuclei through a process known as chromothripsis1–5. As each chromosome contains a single centromere, it remains unclear how

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

open access: yesJournal 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 ...

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

open access: yesJournal 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 ...

DNA replication occurs in all lamina positive micronuclei, but never in lamina negative micronuclei [PDF]

open access: yesMutagenesis, 2011
A micronucleus is a small nucleus-like structure found in the cytoplasm of dividing cells that suffered from genotoxic stress. It is generally hypothesised that micronuclei content is eventually lost from cells, though the mechanism of how this occurs is unknown.

Determination of micronuclei.

open access: yes, 2019
Nuclei were detected using DAPI staining. Percentage of micronucleated cells was enumerated according to DAPI staining. Cadmium treatment promotes micronuclei formation compared to untreated cells.

Cytotoxic and Genotoxic Effects in Buccal Cells of Sandstone Quarry Workers

open access: yesJournal 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 ...

Radiation-Induced Chromosomal Aberrations and Immunotherapy: Micronuclei, Cytosolic DNA, and Interferon-Production Pathway

open access: yesFrontiers in Oncology, 2018
Radiation-induced chromosomal aberrations represent an early marker of late effects, including cell killing and transformation. The measurement of cytogenetic damage in tissues, generally in blood lymphocytes, from patients treated with radiotherapy has ...

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

open access: yesJournal 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.
