Materials and methods

Test guideline
Qualifier:
according to guideline
Guideline:
other: according to E. Routledge and J.P. Sumpter (1996)
Principles of method if other than guideline:
The aim of the study was to determine the estrogenic and antiestrogenic potential of (4nonylphenoxy) acetic acid. The yeast cells used in the yeast estrogen screening (YES) assay have been stably transformed with genes for the human estrogen receptor a and the ß-galactosidase reporter gene. Estrogenic as weil as antiestrogenic potentials of the test substances mediated by receptor binding or blocking can be determined using this assay, respectively.
GLP compliance:
no
Type of method:
in vitro

Results and discussion

Details on results:
ln this study, the test substance showed no estrogenic activity in comparison to 17ß-estradiol. ln this study, the test substance showed no antiestrogenic activity from about 10-5 mol/L in comparison to hydroxytamoxifen.
