Female and male Drosophila melanogaster were exposed separately for seven days to Bisphenol A (BPA), Bisphenol F (BPF), and Bisphenol S (BPS) at concentrations of 0.25, 0.5, and 1 mM. We observed that males exposed to 0.5 and 1 mM BPS showed lower catalase (CAT) activity and higher superoxide dismutase (SOD) and reactive species (RS); CAT activity decreased for BPF 0.5 and 1 mM. Nevertheless, BPA 0.5 and 1 mM decreased CAT activity, increased RS and lipid peroxidation (LPO), and reduced mitochondrial viability. None of the bisphenols altered the cell viability of male flies, although BPA 0.5 and 1 mM reduced longevity. In female flies, BPA and BPS 0.5 and 1 mM increased RS and LPO levels and decreased CAT activity and glutathione-S-transferase (GST), which may have contributed to lower mitochondrial and cell viability. Furthermore, BPS decreased SOD activity at the 1 mM concentration, and BPA reduced the SOD activity at concentrations of 0.5 and 1 mM. In the BPF 1 mM group, there was a reduction in GST activity and an increase in RS and LPO levels. The toxicological effects were different between sexes, and BPA was more harmful than BPF and BPS in male flies. Thus, our findings showed that females were more susceptible to oxidative cell damage when exposed to BPA and BPS than to BPF, and daily exposure to BPA and BPS at all concentrations reduced female longevity, as well as in BPF 1 mM.
雌性和雄性黑腹果蝇分别暴露于双酚 A(BPA)、双酚 F(BPF)和双酚 S(BPS)浓度为 0.25、0.5 和 1 mM 下七天。我们观察到暴露于 0.5 和 1 mM BPS 的雄性显示出较低的过氧化氢酶(CAT)活性和较高的超氧化物歧化酶(SOD)和活性物质(RS);BPF 的 0.5 和 1 mM 浓度下 CAT 活性降低。然而,0.5 和 1 mM 的 BPA 降低了 CAT 活性,增加了 RS 和脂质过氧化(LPO),并降低了线粒体活力。尽管 0.5 和 1 mM 的 BPA 降低了雄性苍蝇的寿命,但没有一种双酚类物质改变了雄性苍蝇的细胞活力。在雌性苍蝇中,BPA 和 BPS 的 0.5 和 1 mM 浓度增加了 RS 和 LPO 水平,降低了 CAT 活性和谷胱甘肽-S-转移酶(GST),这可能导致线粒体和细胞活力降低。此外,BPS 在 1 mM 浓度下降低了 SOD 活性,而 BPA 在 0.5 和 1 mM 浓度下降低了 SOD 活性。在 BPF 1 mM 组中,GST 活性降低,RS 和 LPO 水平升高。这些毒性作用在性别之间存在差异,并且 BPA 在雄性苍蝇中的毒性比 BPF 和 BPS 更大。因此,我们的研究结果表明,与 BPF 相比,雌性在暴露于 BPA 和 BPS 时更容易受到氧化细胞损伤,并且在所有浓度下,BPA 和 BPS 的日常暴露都会降低雌性的寿命,而在 BPF 1 mM 组中也是如此。
