The In Vitro Transgenic Rodent Assay in Primary MutaMouse Hepatocytes Compared to the Mammalian Cell Gene Mutation Assay Using the HPRT Gene

open access: yesEnvironmental and Molecular Mutagenesis, EarlyView.
ABSTRACT Gene mutations can be detected in mammalian cells in vitro using indicator genes such as the hypoxanthine‐guanine‐phosphoribosyltransferase (HPRT) gene. These assays have been adopted as OECD test guidelines (TG, e.g., OECD TG no. 476) and are used for regulatory purposes.

An In Vitro and In Vivo Assessment of the Genotoxic Potential of Maizinol (UP165), a Zea mays Leaf Extract

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Benzoxazinoids are secondary metabolites produced in monocotyledons and some dicotyledons from the Acanthaceae, Ranunculaceae, Scrophulariaceae, Plantaginaceae, and Lamiaceae families. Benzoxazinoids are commonly consumed in bread and cereal products that have been ingested for decades, which supports the safe use of benzoxazinoids as food ...

Abietic Acid Enhances the Sedative Activity of Diazepam: In vivo Approach along with Receptor Binding Affinity and Molecular Interaction with the GABAergic System

open access: yesChemistryOpen, EarlyView.
Abietic acid (AA) reveals potent sedative potential by expressing fast sleeping onset and increased sleeping duration compare to the control group in thiopental sodium induced sleeping mice. The compound also exhibited notable binding affinity (–7.9 kcal/mol) toward GABAA receptors.

Distribution and activity of nitrate and nitrite reductases in the microbiota of the human intestinal tract

open access: yesThe FEBS Journal, EarlyView.
Nitrate from food is first converted to nitrite by oral bacteria and then further processed in the intestine. The gut microbiota reduces nitrate and nitrite to ammonia or nitric oxide, preventing the formation of carcinogenic nitrosamines. Our analysis highlights Escherichia coli as a key player in this detoxification process, supported by other ...
