Popis: Zearalenone (ZEN) is a worldwide fusarotoxin that poses a threat to the consumer due to its chronic toxicity. Herein we examined the effects of ZEN on adult mouse testis, focusing on oxidative stress, biochemical and morphological parameters. In addition, since cytoskeletal remodeling is a key event for the production of good quality gametes, the expression and localization of two proteins, Dishevelled-associated activator of morphogenesis 1 (DAAM1) and Prolyl endopeptidase (PREP), involved in cytoskeletal dynamics during spermatogenesis were evaluated. To ameliorate the testicular dysfunction induced by ZEN we tested the eventual protective effects of lactic bacteria Lactobacillus plantarum MON03 (LP) on its reprotoxicity. Adult male mice were then treated daily for 2 wks by oral gavage with ZEN and/or LP. The results confirmed that ZEN altered sperm parameters, generated oxidative stress and provoked structural alteration, evidenced by the increased number of abnormal seminiferous tubules and of apoptotic cells, particularly Leydig cells. Interestingly, at molecular level we evaluated, for the first time, the ability of ZEN to alter DAAM1 and PREP protein level and localization. Moreover, the co-treatment with LP, thanks to its capacity to reduce ZEN bioavailability in the gastrointestinal tract, ameliorated all the considered parameters. These results suggest the use of this probiotic as food supplement to prevent/counteract ZEN-induced reprotoxicity.
