Mechanisms and Assessment of Genotoxicity of Metallic Engineered Nanomaterials in the Human Environment

Biomedicines
Engineered nanomaterials (ENMs) have a broad array of applications in agriculture, engineering, manufacturing, and medicine. Decades of toxicology research have demonstrated that ENMs can cause genotoxic effects on bacteria, mammalian cells, and animals.

Effects of artichoke (Cynara scolymus) leaf and bloom head extracts on chemically induced DNA lesions in Drosophila melanogaster

Genetics and Molecular Biology, 2014
The genotoxicity of bloom head (BHE) and leaf (LE) extracts from artichoke (Cynara scolymus L.), and their ability to modulate the mutagenicity and recombinogenicity of two alkylating agents (ethyl methanesulfonate - EMS and mitomycin C - MMC) and the ...

Scientific opinion on the renewal of the authorisation of Scansmoke SEF7525 (SF‐004) as a smoke flavouring Primary Product

EFSA Journal, 2023
The EFSA Panel on Food Additives and Flavourings (FAF) was requested to evaluate the safety of the smoke flavouring Primary Product Scansmoke SEF7525 (SF‐004), for which a renewal application was submitted in accordance with Article 12(1) of Regulation ...

Is tetrachloroethylene genotoxic or not? [PDF]

Mutagenesis, 2010
A recent study published in Mutagenesis, in which the ability of tetrachloroethylene to induce DNA damage, detected by the alkaline comet assay, in mouse tissues (liver and kidney) was examined, has resulted in different interpretations of the data for liver as either positive or negative for genotoxicity.

The subcellular distribution of phosphorylated Y‐box‐binding protein‐1 at S102 in colorectal cancer patients, stratified by KRAS mutational status and clinicopathological features

Molecular Oncology, EarlyView.
This study identifies nuclear YB‐1 S102 phosphorylation as a marker associated with KRAS and FBXW7 mutations in colorectal cancer. Mutated KRAS correlates specifically with nuclear, not cytoplasmic, S102 YB‐1. These findings provide the first ex vivo evidence of this link in CRC and suggest future studies should assess the prognostic and therapeutic ...

Genotoxic and antigenotoxic medicinal plant extracts and their main phytochemicals: “A review”

Frontiers in Pharmacology
Many medicinal plant extracts have been proven to have significant health benefits. In contrast, research has shown that some medicinal plant extracts can be toxic, genotoxic, mutagenic, or carcinogenic.

Few-layer graphene induces both primary and secondary genotoxicity in epithelial barrier models in vitro

Journal of Nanobiotechnology, 2021
Background Toxicological evaluation of engineered nanomaterials (ENMs) is essential for occupational health and safety, particularly where bulk manufactured ENMs such as few-layer graphene (FLG) are concerned.

Association of high‐dose radioactive iodine therapy with PPM1D‐mutated clonal hematopoiesis in older individuals

Molecular Oncology, EarlyView.
In thyroid cancer patients, high‐dose (≥7.4 GBq) radioactive iodine therapy (RAIT) was associated with a higher prevalence of clonal hematopoiesis (variant allele frequency >2%) in individuals aged ≥50 years (OR = 2.44). In silico analyses showed that truncating PPM1D mutations conferred a selective advantage under these conditions.

Genotoxicity assessment of chemical mixtures

EFSA Journal, 2019
The EFSA Scientific Committee addressed in this document the peculiarities related to the genotoxicity assessment of chemical mixtures. The EFSA Scientific Committee suggests that first a mixture should be chemically characterised as far as possible ...
