Figure Lengend Snippet: Nrf2 activation inhibits vascular smooth muscle cell (VSMC) migration in a Nrf2-dependent manner. VSMC were synchronized overnight and then stimulated with 25 ng/mL PDGF-BB for 24 h in the presence or absence of Nrf2 activators: 200 nM bardoxolone (BAR), 400 nM omaveloxolone (OMV), or 100 μM cinnamaldehyde (CA). Nrf2 wild-type (WT), knock-out (KO), and Nrf2-rescued (RESC) VSMC were used. (A) Representative images depicting the initial scratch (0 h) and the same region 24 h later showing cell migration toward the wound area. (B) Quantification of cell migration based on the area occupied by cells within the scratch region after 24 h. (One-way ANOVA with post hoc Tukey’s correction for multiple comparisons; ns = not significant, * p < 0.05, ** p < 0.01, *** p < 0.001; data presented as mean ± SD.).

Figure Lengend Snippet: Nrf2 activators upregulate downstream antioxidant enzymes only in Nrf2 wild-type (WT) and rescued vascular smooth muscle cells (VSMC). VSMC were synchronized overnight and then stimulated with 25 ng/mL PDGF-BB for 24 h in the presence or absence of Nrf2 activators: 200 nM bardoxolone methyl (BAR), 400 nM omaveloxolone (OMV), or 100 μM cinnamaldehyde (CA). Nrf2 WT, knock-out (KO), and Nrf2-rescued (RESC) VSMC were used (A) Western blot of HO-1 and NQO1 protein levels after 24 h, across genotypes and treatments.(B) Densitometric quantification of HO-1 and NQO1 expression normalized to loading control ( n = 3 biological replicates (One-way ANOVA with post hoc Tukey’s correction for multiple comparisons; ns = not significant, * p < 0.05, ** p < 0.01, *** p < 0.001; data presented as mean ± SD.).

Figure Lengend Snippet: Nrf2 activation inhibits proliferation only in Nrf2 wild-type (WT) and Nrf2-rescued (RESC) vascular smooth muscle cells (VSMC). VSMC were synchronized overnight and then stimulated with 25 ng/mL PDGF-BB for 24 h with or without Nrf2 activators: 200 nM bardoxolone methyl (BAR), 400 nM omaveloxolone (OMV), or 100 μM cinnamaldehyde (CA). Nrf2 WT, knock-out (KO), and Nrf2-rescued (RESC) VSMC were harvested for flow cytometry. (A, B) Quantification of viable and apoptotic/dead VSMC (n = 3 biological replicates, in triplicate). (C) Percentage of Ki67+ proliferating VSMC across genotypes and treatments ( n = 3; representative replicate shown). (One-way ANOVA with post hoc Tukey’s correction for multiple comparisons; ns = not significant, **** p < 0.0001; data presented as mean ± SD.).

Figure Lengend Snippet: Nrf2 activation preserves the contractile phenotype only in Nrf2 wild-type (WT) and rescued vascular smooth muscle cells (VSMC) under PDGF stimulation. Nrf2 WT, knock-out (KO), and Nrf2-rescued (RESC) VSMC were treated with with 30 mg/mL heparin for 5 days to induce a contractile phenotype, followed by 72 h stimulation with 25 ng/mL PDGF-BB in the presence or absence of Nrf2 activators: 200 nM bardoxolone methyl (BAR), 400 nM omaveloxolone (OMV), or 100 μM cinnamaldehyde (CA).(A) Representative western blots showing expression of contractile markers: calponin, transgelin (SM22α)(B) Densitometric quantification of marker expression across genotypes and treatments ( n = 3 biological replicates).(One-way ANOVA with post hoc Tukey’s correction for multiple comparisons; ns = not significant, * p < 0.05, ** p < 0.01, *** p < 0.001; data presented as mean ± SD.).

Figure Lengend Snippet: Bardoxolone methyl is more potent at inhibiting neointimal hyperplasia after balloon injury in rats. 100 nM bardoxolone methyl (BAR) in 100 μL Pluronic F-127 gel was applied periadventitially at the time of surgery. Arteries were harvested 14 days post-surgery and processed for imaging.
