A Comprehensive Study to Compare Different Compound Representations for Predicting Carcinogenicity In Vivo

Journal of Applied Toxicology, EarlyView.
ABSTRACT Carcinogenicity evaluation is a critical component of chemical risk assessment, yet traditional in vivo testing remains time consuming, costly, and ethically challenging. Computational approaches based on machine learning offer promising alternatives, but the relative contributions of different molecular representation strategies for ...

A Metabolomics Investigation of Non-genotoxic Carcinogenicity in the Rat

, 2016
Non-genotoxic carcinogens (NGCs) promote tumor growth by altering gene expression, which ultimately leads to cancer without directly causing a change in DNA sequence. As a result NGCs are not detected in mutagenesis assays.

Controlling Growth of Ultrasmall Sub‐10 nm Silver Nanoparticles From Cotinus coggygria Scop. Extract and Evaluation of Its In Vitro Anti‐Breast Cancer, Antioxidant and Antimicrobial Activity

Journal of Applied Toxicology, EarlyView.
ABSTRACT This study highlights the potential use of Cotinus coggygria Scop. plant extract in a single‐step synthesis of biocompatible and ultrasmall AgNPs for in vitro applications. Herein, microscopic analyses revealed that AgNP exposure did not induce appreciable morphological changes in CRL‐4010 cells, whereas MCF‐7 and MDA‐MB‐231 cells exhibited ...

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 ...

Cellular Toxicity of Short‐ and Long‐Term Exposures to Polystyrene Nanoplastics and Microplastics in Fish Skin Cell Derived From Fathead Minnow (Pimephales promelas)

Journal of Applied Toxicology, EarlyView.
ABSTRACT The ubiquitous presence of microplastics and nanoplastics (MNPs) is raising concerns about their impact on the health of humans and other living organisms. Due to its tiny size, this particle can accumulate and circulate in the body after uptake, resulting in a variety of harmful outcomes on the organism, such as increased oxidative stress and

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 ...

Potential Neuroendocrine Disruption by Benzodiazepines and Its Impact on Male Fertility

Journal of Applied Toxicology, EarlyView.
ABSTRACT Neuroactive substances have emerged as potent endocrine disruptors affecting male reproductive health through central and peripheral mechanisms. Among these, benzodiazepines, which are widely used for the management of anxiety, insomnia, epilepsy, and neuromuscular disorders, are known as GABA A (gamma‐aminobutyric acid type A) receptor ...

Bisphenol M Induces Dose‐Dependent Hepatic Injury and Fibrotic Remodeling in Female Mice

Journal of Applied Toxicology, EarlyView.
ABSTRACT The safety of bisphenol analogs as alternatives to bisphenol A (BPA) is increasingly concerning. This study investigated the hepatotoxic effects of bisphenol M (BPM), a widely used BPA substitute, in 6‐week‐old female BALB/c mice exposed to 2.5, 5, and 10 mg/kg/day intraperitoneally for 14 days. Hepatic changes were assessed via histopathology,
