Over het archief
Het OWA, het open archief van het Waterbouwkundig Laboratorium heeft tot doel alle vrij toegankelijke onderzoeksresultaten van dit instituut in digitale vorm aan te bieden. Op die manier wil het de zichtbaarheid, verspreiding en gebruik van deze onderzoeksresultaten, alsook de wetenschappelijke communicatie maximaal bevorderen.
Dit archief wordt uitgebouwd en beheerd volgens de principes van de Open Access Movement, en het daaruit ontstane Open Archives Initiative.

| Abstract |
Finding markers directly correlating effects of estrogenic chemicals with the reproductive system of male fish is of great importance. In fish, gamma -glutamyl transpeptidase ( gamma -GTP) has been localised in various tissues, but not in testes. However, in testes of mammals gamma -GTP has been localised to Sertoli cells and used as a Sertoli cell marker. If this also applies to fish, gamma -GTP could be used as a marker of effects on Sertoli cells for studies of estrogenic chemicals. In our earlier studies nonylphenol treatment of eelpout resulted in a marked reduction in testicular gamma -GTP activity concomitant with a reduction in Sertoli cell size. In contrast, treatment of platyfish resulted in a tendency of increased gamma -GTP activity concomitant with a hypertrophy of Sertoli cells. To study our hypothesis of testicular gamma -GTP being a Sertoli cell marker we have examined the relationship between the histological structure of Sertoli cells and gamma -GTP activity in 6 fish species. |
