Its effects on pS2 induction were not eliminated by an anti-androgen. This suggests that at least some of fenvalerate's action may be through a signalling pathway other than the estrogen receptor. At even higher levels it was toxic to the cell-line. The higher the concentration, the lower the pS2 induction. Adapted from Go et al . 1999.
Induction is modest at low levels.
It increases in the middle ranges. But at high concentrations induction disappears.
