Developmental bisphenol A diglycidyl ether (BADGE) exposure causes cell over-proliferation in Drosophila

• Since the estrogenic activity of bisphenol A had been reported, the industry started to find a proper replacement. Bisphenol A diglycidyl ether (BADGE) is one of the derivatives of BPA which is used widely in epoxy resin manufactory. Recently, some studies have demonstrated the adverse effects of BADGE on reproduction and development. However, the knowledge of BADGE is still scarce. Because of its hydrolytic property, BADGE is usually detected at a low level in commodities and the influences seem to be underestimated. In our study, we use the whole transcriptome sequencing to assess the effects of developmental BADGE exposure on Drosophila melanogaster. Notably, the genes related to cell proliferation are significantly affected by BADGE exposure. More detailed, a group of mitotic genes, including string (stg, human CDC25A), Cyclin B (CycB, human CCNB1), Cyclin E (CycE, human CCNE1), and pan gu (png, human NEK11), are detectable overexpressed. Phenotypically, we observe that BADGE induces severe hemocytes over-proliferation in the 3rd instar larvae, but does not cause morphological damage of the larval lymph gland and blood circulation. In conclusion, we provide evidence to show the carcinogenic potential of BADGE and raise the concern of better understanding of xenobiotics.
