Effects of the isoflavones genistein and equol on the gonadal development of Japanese medaka Oryzias latipes.
The estrogenic isoflavone compound genistein recently has been found in the effluents of sewage treatment plants and pulp mills, and the related compound equol has been detected in the runoff from agricultural fields treated with hog manure. Waterborne exposures of Japanese medaka (Oryzias latipes) to equol from soon after hatch to approximately 100 days posthatch induced gonadal intersex (i.e....
متن کاملRelationship between ethinylestradiol-mediated changes in endocrine function and reproductive impairment in Japanese medaka (Oryzias latipes).
Many biochemical endpoints currently are used to describe endocrine function in fish; however, the sensitivity of these parameters as biomarkers of impaired reproduction or sexual development is not well understood. In the present study, adult Japanese medaka (Oryzias latipes) were assessed for reproductive output and endocrine function, including circulating steroid concentrations, ex vivo ste...
متن کاملOccurrence of thymic lymphoma in carcinogenesis bioassay specimens of the Japanese medaka (Oryzias latipes).
Multiple cases of thymic lymphoma were diagnosed in bioassay specimens of Japanese medaka (Oryzias latipes), a small fish species. Lymphoma in chemically exposed specimens was not clearly related to specific compounds, dose, or sex. Multiple cases of lymphoma occurred in three specimens held in one aquarium and in two specimens in two other aquaria, suggesting the possibility of horizontal tran...
متن کاملAnalysis of the Ush2a Gene in Medaka Fish (Oryzias latipes)
Patients suffering from Usher syndrome (USH) exhibit sensorineural hearing loss, retinitis pigmentosa (RP) and, in some cases, vestibular dysfunction. USH is the most common genetic disorder affecting hearing and vision and is included in a group of hereditary pathologies associated with defects in ciliary function known as ciliopathies. This syndrome is clinically classified into three types: ...
متن کاملReproductive Success and Behavior of Japanese Medaka (oryzias Latipes) Exposed to 4-tert-octylphenol
Japanese medaka (Oryzias latipes), a small freshwater fish used extensively to investigate sexual differentiation and development, were exposed to octylphenol (OP), a known estrogen agonist, to assess its impact on reproductive success. Male and female medaka were exposed to nominal concentrations of 10, 25, 50, and 100 mg/L OP from 1 d posthatch to 6 months posthatch. In reproduction trials in...
