Screening for Ames mutagenicity of food flavor chemicals by (quantitative) structure-activity relationship

open access: yesGenes and Environment, 2020
Background (Quantitative) Structure-Activity Relationship ((Q)SAR) is a promising approach to predict the potential adverse effects of chemicals based on their structure without performing toxicological studies.

Mutagenicity comparison of nine bioselenocompounds in three Salmonella typhimurium strains

open access: yesToxicology Reports, 2018
Selenium (Se) is an essential element in animals but becomes severely toxic when the amount ingested exceeds the adequate intake level. It is known that the toxicological effects of Se are highly dependent on its chemical form.

TNF receptor–related factor 3 inactivation promotes the development of intrahepatic cholangiocarcinoma through NF‐κB‐inducing kinase–mediated hepatocyte transdifferentiation

open access: yesHepatology, EarlyView., 2022
Abstract Background and Aims Intrahepatic cholangiocarcinoma (ICC) is a deadly but poorly understood disease, and its treatment options are very limited. The aim of this study was to identify the molecular drivers of ICC and search for therapeutic targets.

Mutagenic impact on fish of runoff events in agricultural areas in south-west France [PDF]

open access: yes, 2011
When heavy rainfall follows herbicide application, the intense surface runoff causes stream water contamination. Aquatic organisms are then briefly exposed to a complex mixture of contaminants.
