Investigating the development toxicity of perfuorinated iodine alkanes(PFIs)is critical,given their estrogenic effects through binding with estrogen receptors(eRs).In the present study,two PFIs,including dodecafuoro-1,6-diiodohexane(PFHx DI)and tridecafuorohexyl iodide(PFHx I),with binding preference to eRαand eRβ,respectively,were selected to evaluate their effects on proliferation and differentiation of the mouse embryonic stem cells(m eSCs).The results revealed that,similar to e_(2),50μmol/L PFHx DI accelerated the cell proliferation of the m *** PFI stimulation at the exposure concentrations of 2–50μmol/L promoted the differentiation of the m eSCs as characterized by the upregulation of differentiation-related biomarkers(i.e.,Otx2 and Dnmt3β)and downregulation of pluripotency genes(i.e.,Oct4,Nanog,Sox2,Prdm14 and Rex1).Comparatively,PFHx DI exhibited higher induction effect on the differentiation of the m eSCs than did PFHx *** tests on eR signaling indicated that both PFI compounds induced exposure concentration-dependent expressions of eR signaling-related biomarkers(i.e.,eRα,eRβand Caveolin-1)in the m eSCs,and the downstream eR responsive genes(i.e.,c-fos,c-myc and c-jun)well responded to PFHx I *** role of eR in PFI-induced effects on the m eSCs was further validated by the antagonistic experiments using an eR inhibitor(ICI).The findings demonstrated that PFIs triggered eR signaling,and perturbed the differentiation program of the m eSCs,causing the potential health risk during early stage of development.
