Effect of Bisphenol A on invasion ability of human trophoblastic cell line BeWo.

ABSTRACT: Bisphenol A (BPA) is a kind of environmental endocrine disruptors (EEDs) that interfere embryo implantation. Trophoblast invasion plays a crucial role during embryo implantation. In this study, the effects of BPA on invasion ability of human trophoblastic cell line BeWo and its possible mechanism were investigated. BeWo cells were exposed to BPA and co-cultured with human endometrial cells to mimic embryo implantation in transwell model. The proliferation and invasion capability of BeWo cells were detected. The expression of E-cadherin, DNMT1, MMP-2, MMP-9, TIMP-1 and TIMP-2 were also analyzed. The results showed that the invasion capability of BeWo was reduced after daily exposure to BPA. BPA had biphasic effect on E-cadherin expression level in BeWo cells and expression level of DNMT1 was decreased when treated with BPA. Moreover, BPA treatment also changed the balance of MMPs/TIMPs in BeWo cells by down-regulating MMP-2, MMP-9 and up-regulating TIMP-1, TIMP-2 with increasing BPA concentration. Taken together, these results showed that BPA treatment could reduce the invasion ability of BeWo cells and alter the expression level of E-cadherin, DNMT1, TIMP-1, TIMP-2, MMP-2, and MMP-9. Our study would help us to understand the possible mechanism of BPA effect on invasion ability of human trophoblastic cell line BeWo.

Project description:Classical treatment for congenital toxoplasmosis is based on combination of sulfadiazine and pyrimethamine plus folinic acid. Due to teratogenic effects and bone marrow suppression caused by pyrimethamine, the establishment of new therapeutic strategies is indispensable to minimize the side effects and improve the control of infection. Previous studies demonstrated that enrofloxacin and toltrazuril reduced the incidence of Neospora caninum and Toxoplasma gondii infection. The aim of the present study was to evaluate the efficacy of enrofloxacin and toltrazuril in the control of T. gondii infection in human trophoblast cells (BeWo line) and in human villous explants from the third trimester. BeWo cells and villous were treated with several concentrations of enrofloxacin, toltrazuril, sulfadiazine, pyrimethamine, or combination of sulfadiazine+pyrimethamine, and the cellular or tissue viability was verified. Next, BeWo cells were infected by T. gondii (2F1 clone or the ME49 strain), whereas villous samples were only infected by the 2F1 clone. Then, infected cells and villous were treated with all antibiotics and the T. gondii intracellular proliferation as well as the cytokine production were analyzed. Finally, we evaluated the direct effect of enrofloxacin and toltrazuril in tachyzoites to verify possible changes in parasite structure. Enrofloxacin and toltrazuril did not decrease the viability of cells and villous in lower concentrations. Both drugs were able to significantly reduce the parasite intracellular proliferation in BeWo cells and villous explants when compared to untreated conditions. Regardless of the T. gondii strain, BeWo cells infected and treated with enrofloxacin or toltrazuril induced high levels of IL-6 and MIF. In villous explants, enrofloxacin induced high MIF production. Finally, the drugs increased the number of unviable parasites and triggered damage to tachyzoite structure. Taken together, it can be concluded that enrofloxacin and toltrazuril are able to control T. gondii infection in BeWo cells and villous explants, probably by a direct action on the host cells and parasites, which leads to modifications of cytokine release and tachyzoite structure.
