4-tert-Octylphenol, a endocrine-disrupting chemical, is an estrogenic drug. 4-tert-Octylphenol induces apoptosis in neuronal progenitor cells in offspring mouse brain. 4-tert-Octylphenol reduces bromodeoxyuridine (BrdU), mitotic marker Ki67, and phospho-histone H3 (p-Histone-H3), resulting in a reduction of neuronal progenitor proliferation. 4-tert-Octylphenol disrupts brain development and behavior in mice[1].
