In the present study, effect of exposure of bisphenol A (BPA) and combined exposure of BPA + HSD has been investigated on the glucose homeostasis and associated renal complications in Drosophila. Exposure of 1.0 mM BPA alone induced type 2 diabetes like condition (T2D) in adult male D. melanogaster via oxidative stress. Elevated TGF-β signaling was evident by increased expression of baboon (babo) in BPA exposed organism that stimulated the modulation of extracellular matrix (ECM) component collagen IV resulting in the fibrosis of the Malpighian tubules (MTs). Combined exposure of BPA + HSD (high sucrose diet) resulted in the increased magnitude of T2D and MTs dysfunction parameters. Taken together, the study illustrates that BPA has diabetogenic potential in exposed Drosophila that caused adverse effects on their MTs and combined exposure with BPA and HSD could aggravate the renal tubular dysfunction. The study further suggests the use of Drosophila model to study the environmental chemicals induced diabetes mediated renal dysfunction.
在本研究中,研究了双酚 A(BPA)暴露和 BPA+HSD 联合暴露对果蝇葡萄糖稳态和相关肾脏并发症的影响。单独暴露于 1.0mM BPA 通过氧化应激诱导成年雄性黑腹果蝇出现 2 型糖尿病样状态(T2D)。在 BPA 暴露的生物体中,babo(狒狒)的表达增加表明 TGF-β信号通路被激活,这刺激了细胞外基质(ECM)成分胶原蛋白 IV 的调节,导致了马氏管(MTs)的纤维化。BPA+HSD(高蔗糖饮食)的联合暴露导致 T2D 和 MTs 功能障碍参数的增加幅度增大。总之,该研究表明,BPA 在暴露的果蝇中具有致糖尿病的潜力,这对它们的 MTs 产生了不良影响,而与 BPA 和 HSD 的联合暴露可能会加重肾小管功能障碍。该研究进一步表明,使用果蝇模型来研究环境化学物质诱导的糖尿病介导的肾功能障碍。
