Abstract

The estrogen-disrupting effects and mechanism of perfluorocarboxylic acids (PFCAs), with similar structures to perfluorooctanoic acid (PFOA), are poorly understood. The purpose of the present study is to explore the estrogen-disrupting effects of PFCAs through the estrogen-related receptor γ (ERRγ) pathway. In vitro, similar to an ERRγ Agonist, perfluorohexanoic acid (PFHxA), perfluoroheptanoic acid (PFHpA), PFOA, perfluorononanoic acid (PFNA) and perfluorodecanoic acid (PFDA) induced proliferation of human endometrial Cancer cell Ishikawa at human exposure-related concentrations by binding and activating ERRγ. In vivo, PFHxA, PFOA and PFDA induced ovarian damage in zebrafish at 3.2 μM, 2.4 μM and 1.9 μM, respectively. PFCAs also induced sex Hormones disturbance and interfered with sex hormone synthesis- and ERRγ pathway-related gene expression. In particular, PFOA exhibited estrogen-disturbing effects at the environmentally relevant concentration. Maternal exposure to PFCAs produced abnormal development of zebrafish offspring by disturbing the sex Hormones and ERRγ pathway-related gene expression. All the effects were mitigated by an ERRγ Antagonist. In conclusion, PFCAs could cause estrogen-disrupting effects and transgenerational effects through the ERRγ pathway. The study revealed a novel insight into the estrogen-disrupting effects of PFCAs.
