Mosaic activation of the zebrafish hsp70l heat shock promoter: Implications for interpreting transgenes

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The promoters and enhancers of heat shock genes, such as the 1.5‐kb promoter of the zebrafish hsp70l gene, are valuable tools for temporal activation of transgenes. It has been widely purported that heat shock treatments result in ubiquitous expression of hsp70l‐driven transgenes.

Development of a Zebrafish Embryo‐Based Test System for Thyroid Hormone System Disruption: 3Rs in Ecotoxicological Research

open access: yesEnvironmental Toxicology and Chemistry, EarlyView.
Abstract There is increasing concern regarding pollutants disrupting the vertebrate thyroid hormone (TH) system, which is crucial for development. Thus, identification of TH system–disrupting chemicals (THSDCs) is an important requirement in the Organisation for Economic Co‐operation and Development (OECD) testing framework.

Residence Near Agricultural Crops at Birth and Risk of Adult Testicular Germ Cell Tumors: A French Nationwide Case–Control Study Using Historical Aerial GIS Data

open access: yesInternational Journal of Cancer, EarlyView.
As the incidence of testicular germ cell tumors (TGCTs) rises, prenatal exposure to agricultural pesticides may represent an important risk factor. Here, geographic information system‐based measures of farmland proximity at birth were used as a proxy for early‐life pesticide exposure in France, a major pesticide consumer.
