Abstract
Microplastics (MPs), as a novel type of environmental pollutant, have the potential to impact human health. This study aims to investigate the protective efficacy of active compounds in licorice on microplastics-injured rats and reveal the underlying mechanisms. The MPs-injured rat model was established by orally administrated with MPs. After the treatment with different doses of a combination of liquiritigenin, isoliquiritigenin and glycyrrhetinic acid, the tissue injury, oxidative stress, inflammation and expressions of tight junction proteins in colon and liver were evaluated. Our data showed that active compounds of licorice significantly ameliorate colonic and liver damage caused by MPs, improving function colonic barrier and liver function, reducing oxidative stress and systemic inflammatory factors. Then, a total of 29 differentially expressed proteins were identified by label-free proteomics analysis, among which the down-regulated Fas-associating protein with a novel death domain (FADD) was found to be the most related with the protective effects of licorice. What’s more, this protein target also interacts directly with active compounds of licorice, through hydrogen bounds and hydrophobic interactions involving 11 residues. This study suggested that licorice exerts protective effects against MPs on rats, through down-regulating as well as directly interacting with FADD.
期刊介绍:
Food and Chemical Toxicology (FCT), an internationally renowned journal, that publishes original research articles and reviews on toxic effects, in animals and humans, of natural or synthetic chemicals occurring in the human environment with particular emphasis on food, drugs, and chemicals, including agricultural and industrial safety, and consumer product safety. Areas such as safety evaluation of novel foods and ingredients, biotechnologically-derived products, and nanomaterials are included in the scope of the journal. FCT also encourages submission of papers on inter-relationships between nutrition and toxicology and on in vitro techniques, particularly those fostering the 3 Rs.
The principal aim of the journal is to publish high impact, scholarly work and to serve as a multidisciplinary forum for research in toxicology. Papers submitted will be judged on the basis of scientific originality and contribution to the field, quality and subject matter. Studies should address at least one of the following:
-Adverse physiological/biochemical, or pathological changes induced by specific defined substances
-New techniques for assessing potential toxicity, including molecular biology
-Mechanisms underlying toxic phenomena
-Toxicological examinations of specific chemicals or consumer products, both those showing adverse effects and those demonstrating safety, that meet current standards of scientific acceptability.
Authors must clearly and briefly identify what novel toxic effect (s) or toxic mechanism (s) of the chemical are being reported and what their significance is in the abstract. Furthermore, sufficient doses should be included in order to provide information on NOAEL/LOAEL values.
