Regulation of zebrafish (Danio rerio) locomotor behavior and circadian rhythm network by environmental steroid hormones
Environmental exposure of fish to steroid hormones through wastewater and agricultural runoff may pose a health risk. Thus far, ecotoxicological studies have largely been focused on the disruption of the sex hormone system, ...
Occurrence and ecotoxicological effects of free, conjugated, and halogenated steroids including 17a-hydroxypregnanolone and pregnanediol in Swiss watewater and surface water
Apart from estrogens, the occurrence and ecotoxicity of steroids in aquatic environments is poorly known. Here, we analyzed 33 steroids, including estrogens, androgens, progestins, and glucocorticoids, in hospital wastewaters, ...
Reproductive and transcriptional effects of the antiandrogenic progestin chlormadinone acetate in zebrafish (Danio rerio)
Chlormadinone acetate (CMA) is a frequently used progestin with antiandrogenic activity in humans. Residues may enter the aquatic environment but potential adverse effects in fish are unknown. While our previous work focused ...
