Figure Lengend Snippet: Fig. 7. miR-155 targets SOCS-1 to regulate inflammatory response in macrophages. A: wild-type 3=-UTR of mouse SOCS-1 (SOCS-1 3=-UTR) or miR-155 binding deficient mutant 3=-UTR of mouse SOCS-1 (mutSOCS-1 3=-UTR) was separately inserted into the pMIR-REPORT miRNA expression reporter vector. Then these vectors were combined with either miR-155 mimics mmu-miR-155-5p miRNA precursor (Pre-miR-155) or miRNA precursor negative control (Scramble) to be cotransfected into HEK-293T cells. The luciferase activity of the reporter vector was assayed, and the relative activity was compared between groups. n 3 samples per group. *P 0.05 vs. control miRNA and SOCS-1 3=-UTR cotransfected group. B: BMDMs were transfected with SOCS-1 siRNA or control nonsense siRNA. Protein levels of SOCS-1 in cell lysates after transfection were assayed by Western blot analysis. C and D: BMDMs were differentiated from miR-155/ mice or WT control mice, respectively. Then these cells were transfected with either SOCS-1 siRNA or control nonsense siRNA. Immediately after transfection, BMDMs were treated with LPS (100 ng/ml) for 6 h, and mRNA levels of TNF- (C) and IL-6 (D) were assayed by real-time PCR analysis. n 3 samples per group.*P 0.05 vs. BMDMs from WT mice transfected with control siRNA. #P 0.05 vs. BMDMs from WT mice transfected with SOCS-1 siRNA. E: miR-155/ BMDMs transfected with either Pre-miR-155 or miRNA Scramble Control. Then, these cells were transfected with lentivirus expressing SOCS-1 cDNA tagged with a mutated SOCS-1 3=UTR (mutSCOS-1), which was unable to bind miR-155. An empty lentivirus vector (lentiviral vector) was used as a control. At 72 h after transfection, protein levels of SOCS-1 in transfected cells were assayed by Western blot analysis. F and G: 72 h after BMDMs were transfected with indicated miRNAs and lentivirus, BMDMs were stimulated with LPS for 6 h. mRNA levels of TNF- (F), and IL-6 (G) were assayed by real-time PCR analysis. n 3 samples per group. *P 0.05 vs. BMDMs transfected with Pre-miR-155 and lentiviral vector. #P 0.05 vs. BMDMs transfected with Scramble and mutSOCS-1. §P 0.05 vs. BMDMs transfected with Scramble and lentiviral vector.

Article Title: Nitrate attenuates cisplatin-induced acute kidney injury by promotion of mitophagy and reduction of oxidative stress

doi: 10.1007/s44194-023-00024-3

Figure Lengend Snippet: Fig. 1 Inorganic nitrate (NaNO3) inhibits cisplatin-induced injury in vitro. Nacl was used as osmotic control of NaNO3. A HK2 cells were exposed to cisplatin (0, 5, 10, 20 μmol/L) for 24, 48 or 72 h, and the cell viability was determined by CCK8. B HK2 cells were incubated with NaNO3 or Nacl (0, 1, 10, 20, 50, 100 mmol/L) for 48 h, and the cell viability was determined. C, D HK2 or NRK52E cells were treated with cisplatin (20 μmol/L) and were incubated with NaNO3 (20 mmol/L) for 48 h, and the cell viability was determined. E, F The effects of NaNO3 on cisplatin-induced apoptosis in HK2 or NRK52E cells were determined by flow cytometry assay. G-I Whole HK2 cell lysates were collected for immunoblot analysis of Bax, Bcl-2 and β-actin (loading control). (G) Representative blots. Three independent experiments to quantify Bax (H) and Bcl-2 (I). Data are shown as the means ± SEM and analyzed by one-way ANOVA with Tukey’s test. * P < 0.05, ** P < 0.01, *** P < 0.001 vs. Ctrl; # P < 0.05, ## P < 0.01, ### P < 0.001 vs. Cisp; NS, no significance (Ctrl, control; NaNO3, Nitrate; Cisp, cisplatin; Cisp + NaNO3, cisplatin + Nitrate)
