      Activity of binary mixtures of drospirenone with progesterone and 17?-ethinylestradiol in vitro and in vivo 

      Rossier, Nadine Madeleine; Chew, Geraldine; Zhang, Kun; Riva, Francesco; Fent, Karl (2016-02-22)
      Aquatic Toxicology
      Despite potential exposure of aquatic organisms to mixtures of steroid hormones, very little is known on their joint activity in fish. Drospirenone (DRS) is a new synthetic progestin used in contraceptive pills in combination ...

      Corticosteroid Fludrocortisone Acetate Targets Multiple End Points in Zebrafish (Danio rerio) at Low Concentrations 

      Zhao, Yanbin; Zhang, Kun; Fent, Karl (2016-09-12)
      Environmental Science & Technology
      Synthetic corticosteroids may pose an environmental risk to fish. Here, we describe multiend point responses of adult zebrafish (8 months old) upon 21-day exposure to a commonly prescribed corticosteroid, fludrocortisone ...

      Determination of two progestin metabolites (17a-hydroxypregnanolone and pregnanediol) and different classes of steroids (androgens, estrogens, clorticosteroids, progestins) in rivers and wastewaters by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) 

      Fent, Karl; Zhang, Kun (2018)
      Science of the Total Environment
      A highly sensitive and robust method was developed for routine analysis of two progestin metabolites, 17α-hydroxypregnanolone (17OH-Δ5P) and pregnanediol (PD), and 31 other natural and synthetic steroids and related ...

      Environmental chemicals affect circadian rhythms. An underexplored effect influencing health and fitness in animals and humans 

      Zheng, Xuehan; Zhang, Kun; Zhao, Yanbin; Fent, Karl (2021-04)
      Environment International
      Circadian rhythms control the life of virtually all organisms. They regulate numerous aspects ranging from cellular processes to reproduction and behavior. Besides the light-dark cycle, there are additional environmental ...

      Occurrence and ecotoxicological effects of free, conjugated, and halogenated steroids including 17a-hydroxypregnanolone and pregnanediol in Swiss watewater and surface water 

      Fent, Karl; Zhang, Kun; Zhao, Yanbin (2017)
      Environmental Science & Technology
      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, ...

      Regulation of zebrafish (Danio rerio) locomotor behavior and circadian rhythm network by environmental steroid hormones 

      Fent, Karl; Zhao, Yanbin; Zhang, Kun (2018-01)
      Environmental Pollution
      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, ...

      Reproductive and transcriptional effects of the antiandrogenic progestin chlormadinone acetate in zebrafish (Danio rerio) 

      Zhang, Kun; Fent, Karl; Siegenthaler, Patricia Franziska; Zhao, Yanbin (2017)
      Environmental Pollution
      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 ...
