Cellular and molecular mechanisms of action of linuron: an antiandrogenic herbicide that produces reproductive malformations in male rats. Horny corner long beach adenocarcinoma in mice following developmental treatment with oestrogens: a model for hormonal carcinogenesis. NCBI Skip to main. Fenitrothion is an exceptionally potent androgen antagonist in vivo also first evidence in teleosts. This is the mechanism used to extract data from the system using a CSV template. The next step involved in adapting the spiggin bioassay for antiandrogens was to obtain a dose—response curve for FL-induced inhibition of spiggin production. However, the length of the study and the nonwater-borne exposure preclude any comparisons of the sensitivity of the bioassay with the stickleback assay.
