Abstract

• Age-dependent action of nonylphenol (NP) on mouse neuronal cells was demonstrated. • Estrogen receptor (ER) antagonists potentiated the NP-induced apoptosis and toxicity. • ER agonists inhibited the NP-evoked effects in mouse hippocampal cells. • The retinoid X receptor (RXR) antagonist inhibited the NP-induced apoptosis. • NP reduced ERα- and ERβ-staining but stimulated RXR-specific immunofluorescence.
