Issues raised by the presence in the environment of chemicals able to mimic or antagonize the action of androgenic hormones are of growing concern. Here we report the development of a novel in vitro test for the screening of (anti-)androgenic chemicals, based on primary cultures of stickleback kidney cells that produce a protein, the spiggin, in response to androgenic stimulation. Cell spiggin content...
This study investigated the suitability of juvenile three-spined sticklebacks, Gasterosteus aculeatus L., for detecting both androgen- and oestrogen-induced endocrine disruption. The investigated endpoints were kidney hypertrophy and the induction of the protein markers spiggin and vitellogenin. Juveniles were exposed to steroid hormones 17β-oestradiol (E2: nominal 0.01, 1.0 and 10μg/L), 17α-ethinylestradiol...
