Food Safety Publications

The Food Safety Publications tracks research that is published across national and international peer-reviewed journals. Recent articles are available ahead of print and searchable by Journal, Article Title, and Category. The research publications are tracked across six categories: Bacterial Pathogens, Chemical Contaminants, Natural Toxins, Parasites, Produce Safety, and Viruses. Articles produced by USDA Grant Funding Agencies and FDA Grant Funding Agencies are also tracked.

  7. Deoxynivalenol enhances estrogen receptor alpha-induced signaling by ligand-independent transactivation

    • Wed, 05/18/2022 - 05:00
    • Food and Chemical Toxicology
    • Deoxynivalenol (DON), which is one of the prevalent mycotoxins in food and feeds, exerts adverse effects on animal and human health. These effects are mainly associated with its ribotoxic properties, although few studies suggest the involvement of other mechanisms of action. To assess the ability of DON to disrupt estrogen signaling, we conducted an in vitro study using MCF-7 and MDA-MB-231 cells.

Electrochemiluminescence (ECL) is a popular sensing method because of its low background interference and high sensitivity. However, existing ECL assays for AFB1 detection are based on aqueous rather than oil systems.
