    TargetMol nrf2 inhibitor
    TIGAR activated nuclear factor erythroid-2 related factor <t>(Nrf2)</t> to reduce dexamethasone (Dex)-induced oxidative stress through inducing autophagy. Bone marrow mesenchymal stem cells (BMSCs) were transfected with TIGAR overexpression plasmid and treated with Dex. (A, B) Immunofluorescence staining of Nrf2 of BMSCs and the quantification of the integrated optical density (IOD) per field. Scale bars, 50 μm. (C, D) Western blot analysis and quantification of Nrf2 expression in extracted nuclear proteins. (E, F) ROS level under Dex treatment in BMSCs with or without administration of 10 nM Nrf2 inhibitor <t>(ML385)</t> after transfecting with TIGAR overexpression plasmid, and the quantification of IOD per filed. Scale bars, 100 μm. BMSCs were treated with Dex and chloroquine (CQ) (20 μM) after transfecting with TIGAR overexpression plasmid. (G–I) Western blot analysis and quantification of p62 and LC3-II expression under different treatments. (J, K) Representative images of mCherry-GFP-LC3 puncta and number of autophagosomes (yellow) (analyzed by Pearson's correlation). Scale bars, 50 μm. (L–N) Western blot analysis and quantification of Nrf2 and kelch-associated protein 1 (Keap1) expression under different treatments. (O, P) The immunofluorescence staining of Nrf2 in BMSCs and the quantification of the IOD per field. Scale bars, 50 μm. (Q, R) Representative immunofluorescence images of LC3 and Keap1. Pearson's correlation of co-localization is shown in the bar graph format from the three independent experiments analyzed. Scale bars, 50 μm. (S, T) Representative images of ROS and the quantification of the IOD per field. Scale bars, 100 μm. Data are shown as mean ± SEM. n = 3, biologically independent samples. Two-way analysis of variance (ANOVA) with Tukey's multiple comparisons test was used to assess statistical significance. ∗ p < 0.05, ∗∗ p < 0.01. NC, negative control. OE, TIGAR overexpression plasmid.
