Treatment with LIPUS strengthened ferroptosis-related antioxidative stress and improved the function of mitochondria in the ADR-induced CKD rat. (A) The protein expression levels of glutathione peroxidase 4 (GPX4), solute carrier family 7 member (SLC7A11) and acyl-CoA synthetase long-chain family member 4 (ACSL4) in rat kidney tissue were assayed by western blotting (WB). Relative expression levels of GPX4 (B), SLC7A11 (C) and ACSL4 (D) in each group. The mRNA expression level of GPX4 (E) in rat kidney tissue were proved by real-time quantitative polymerase chain reaction (RT-qPCR). The levels of total superoxide dismutase (T-SOD) (F), glutathione (GSH) (G) and glutathione peroxidase (GSH-Px) (H) in rat kidney tissue were assayed by enzyme linked immunosorbent assay (ELISA). (I) Ultrastructural alterations of tubular epithelial cells (TECs) were analysed using transmission electron microscopy. scale bar, 2.0μm/0.2μm. Abbreviations: BM, basement membrane; FP, foot process; M, mitochondria. Data represent the mean ± standard error of the mean (SEM) for 6 rats in each group. *p < 0.05, ** p < 0.01, ***p < 0.001, **** p < 0.0001.
