Název v původním jazyce

Use of all-male triploid population of zebrafish (Danio rerio) for evaluation of 17 alpha-ethinylestradiol effects

Popis výsledku v původním jazyce

Objectives: We tested the toxicity of ethinylestradiol, a semisynthetic estrogen used in oral contraceptives, on all-male triploid zebrafish using commercial feeds and three different doses concentrations. We aimed to determine whether ethinylestradiol peroral administration resulted in vitellogenin production and whether all-male triploid zebrafish could serve as a model species for xenoestrogen testing. Methods: The actual concentrations of 17α-ethinylestradiol were 0.0035 (low); 0.0315 (medium) and 0.365 (high) µg/g. Positive control represented commercial feeds containing 0.0465 µg/g of β-estradiol. The experiment lasted 8 weeks. Results: Our results indicate that 17α-ethinylestradiol consumption does induce vitellogenin production in triploid zebrafish. Conclusions: The simple presence of vitellogenin is a definite symptom indicative of the potential for such changes due to the action of estrogenic substances. As such, this experiment has shown that the use of all-male triploid zebrafish populations, rather than the mixed-sex populations of other species previously used, could serve as a suitable alternative model population for controlled testing of the effects of xenoestrogens on fish.
