Fig. 1. Renal tubular epithelial cells undergo ferroptosis in I/R-AKI. (A) Single-cell sequencing identified clusters in both sham-operated and I/R-operated kidneys at day 3 post-surgery, depicted in a t-distributed stochastic neighbor embedding (tSNE) map. PT, proximal tubule; DT, distal convoluted tubule; LOH, ascending loop of Henle; ECs, endothelial cells. (B) Average expression levels of mouse single cell type-specific genes are shown in pheatmap. Mean expression values of the genes were calculated in each cluster. The full list of cell types and genes is shown in Additional file1: Table S1. (C-E) Subtypes of PT with differentially expressed genes are illustrated in a tSNE plot (C), and the representative marker genes across the 3 subtypes of PT are depicted in pheatmap (D) and VlnPlot (E). (F-G) The expression levels of ferroptosis-associated genes Gpx4 and Acsl4 in the subtypes of PT were identified by FeaturePlot (F) and Dotplot (G). (H-I) Western blot (H) and statistical analysis (I) of the expression levels of GPX4 and SLC7A11 proteins in the renal cortex of sham-operated and I/R-operated mice post-surgery. ***p 

Figure 3 Deoxycholic acid enhanced lipopolysaccharide-induced ferroptosis in intestinal epithelial cells (A–H) IEC-6 cells and Caco-2 cells were incubated with or without 10 ng/mL LPS for 12 h, followed by 200 μM DCA for 2 h. They were divided into four group (n = 6 in each group): control group, DCA group, LPS group and LPS + DCA group. (A) The relative mRNA expression level of GPX4 in each group of IEC-6 cells and Caco-2 cells (n = 6 in each group). (B) The relative mRNA expression level of ACSL4 in each group of IEC-6 cells and Caco-2 cells (n = 6 in each group). (C) The protein level of GPX4, ACSL4 and β-actin in each group of IEC-6 cells and Caco-2 cells. (D) Representative transmission electron microscopy images (scale bars, 1 μm) of cell and mitochondria, and Fe2+/Hoechst immunofluorescence in each group of IEC-6 cells. Mitochondria was showed by white arrows in the pictures. The red fluorescence is indicative of the presence of ferrous ions. (E) The content of Fe2+ in each group of IEC-6 cells and Caco-2 cells (n = 6 in each group). (F) The content of GSH in each group of IEC-6 cells and Caco-2 cells (n = 6 in each group). (G) The content of ROS in each group of IEC-6 cells and Caco-2 cells (n = 6 in each group). (H) The content of MDA in each group of IEC-6 cells and Caco-2 cells (n = 6 in each group). (I-K) IEC-6 cells were incubated 2 μM ferrostatin-1 (Fer-1) for 16 h, and then incubated with or without 10 ng/mL LPS for 12 h, followed by 200 μM DCA for 2 h. They were divided into six group (n = 5 or 6 in each group): control group, LPS group, LPS + DCA group, Fer-1 group, LPS + Fer-1 group and LPS + DCA + Fer-1 group. (I) The relative mRNA expression level of GPX4, ACSL4 and DMT1 in each group of IEC-6 cells (n = 6 in each group). (J) The content of GSH in each group of IEC-6 cells (n = 5 in each group). (K) The content of MDA in each group of IEC-6 cells (n = 5 in each group). Data are represented as mean ± SEM. ns P > 0.05, ∗P < 0.05, ∗∗P < 0.01, ∗∗∗P < 0.001, ∗∗∗∗P < 0.0001. ##P < 0.01, ####P < 0.0001. ∗ LPS group vs control group, LPS + DCA group vs LPS group. # LPS + Fer-1 group vs LPS group, LPS + DCA + Fer-1 group vs LPS + DCA group.
