However, the phenotype of kidney injury induced by BPS exposure and the mechanism of its damage remain unknown. Therefore, this study aims to investigate the phenotype and specific mechanism of kidney injury induced by BPS exposure. SD rats are treated with three different doses of BPS (50 mg/kg body weight(b.w.), 100 mg/ kg b.w., and 150 mg/ kg b.w.), and HK-2 cells are treated with 100 µM BPS, 200 µM and 400 µM BPSto mimic the in vitro and in vivo environment of BPS exposure-induced kidney injury. Meanwhile, the potential mechanism of BPS exposure-induced kidney injury was screened by RNA sequencing and further verified by in vitro experiments. BPS exposure induces cytoskeletal architecture damage and EMT transformation in HK-2 cells, promoting renal fibrosis. In addition, it was found that activation of the PI3K-AKT-mTOR signaling pathway plays a key role in cytoskeletal architecture damage and EMT transformation in HK-2, and after inhibition of PI3K-AKT-mTOR signaling by Wortmannin, the cytoskeletal architecture disorders, and EMT are partially reversed. In conclusion, we found that the activation of the PI3K-AKT-mTOR signaling pathway can mediate disturbed cytoskeletal architecture and EMT to induce renal fibrosis after BPS exposure.  \nKeywords Bisphenol S, Cytoskeleton, EMT, Fibrosis  \nAt present, environmental pollution has seriously threatened human health. Damage from environmental pollutants, including PM2.5/microplastics/DEHP/BPA, is a current research hotspot. As a common ingredient in polycarbonate plastics and epoxy resin, bisphenol A (BPA) is one of the most productive chemical production products in the world1. It is widely used in a variety of packaging materials toys and containers and other consumer goods2,3. BPA exposure has been demonstrated to cause damage to multiple systems including reproduction, endocrine, and circulation4–6. Because of the huge health risks associated with BPA, many regulators have banned its use. Bisphenol S (BPS; 2,2–2 [4-hydroxyphenol] sulfone) is considered a good alternative to BPA  \n1Department of Paediatrics, The Second Affiliated Hospital of Chongqing Medical University, Chongqing 400014, People’s Republic of China. 2Department of Urology, Children’s Hospital of Chongqing Medical University, Chongqing 400014, People’s Republic of China. 3Chongqing Key Laboratory of Children Urogenital Development and Tissue Engineering, Chongqing 400014, People’s Republic of China. 4China International Science and Technology Cooperation Base of Child Development and Critical; National Clinical Research Center for Child Health and Disorders, Chongqing; Ministry of Education Key Laboratory of Child Development and Disorders, Chongqing Key Laboratory of Pediatrics, Chongqing 400014, People’s Republic of China. 5Institute of Basic Medicine and Cancer (IBMC), Chinese Academy of Sciences, Hangzhou 310022, Zhejiang, People’s Republic of China. 􀀍 email:  \n[liwang8771@126.com](liwang8771@126.com); [hedawei@hospital.cqmu.edu.cn](hedawei@hospital.cqmu.edu.cn)  \n[www. nature.com/scientificreports/](www. nature.com/scientificreports/)  \nin industrial applications and has gradually replaced BPA in canned and other prepackaged foods7.
