Figure Lengend Snippet: Rg3@PACVs attenuate oxidative stress and mitochondrial dysfunction in hypoxia/reoxygenation (H/R)-injured lung epithelial cells (A) Reactive oxygen species (ROS) levels detected by flow cytometry using DCFH-DA probe. (B) Intracellular total superoxide dismutase (T-SOD) activity. (C) Malondialdehyde (MDA) content. (D) Glutathione/oxidized glutathione (GSH/GSSG) ratio. (E) Immunofluorescence detection of nuclear-factor-erythroid-2-related factor 2 (NRF-2, green) and heme oxygenase-1 (HO-1, red). Nuclei counterstained with DAPI (blue). Scale bars, 100 μm. (F) Mitochondrial membrane potential assessed by JC-1 staining. (G) Super-resolution microscopy of mitochondrial ultrastructure (red) in epithelial cells. Lower panel shows magnified views (∗ represents damaged mitochondria, Scale bars, 5 μm). (H–L) Mitochondrial respiration in BEAS-2B cells under different stimulation conditions was assessed by measuring the oxygen consumption rate (OCR) using a Seahorse XF96 analyzer (H). Key parameters including basal respiration (I), maximal respiration (J), proton leak (K), and ATP production (L) were calculated. Data are presented as the mean ± SD and analyzed using one-way ANOVA with Tukey’s post hoc test ( ∗ p < 0.05, ∗∗ p < 0.01, ∗∗∗ p < 0.001 vs. control; # p < 0.05, ## p < 0.01, ### p < 0.001 vs. H/R; & p < 0.05, && p < 0.01, &&& p < 0.001 vs. H/R + Rg3@PACVs; n = 4 biological replicates).

Article Title: USP1 promotes hepatocellular carcinoma progression by modulating mitophagy via stabilizing MCM3 to regulate the Keap1-Nrf2 axis

doi: 10.1016/j.isci.2026.114927

Figure Lengend Snippet: MCM3 regulates mitophagy by influencing the expression and localization of Nrf-2 (A) WB used to detect the impact of MCM3 knockdown on P62, LC3B II/I, TOMM20, FUNDC1, Parkin, and PINK1 in Huh7 and LM3 cells. (B) WB was used to assess the impact of MCM3 knockdown on Nucleus Nrf2 in Huh7 and LM3 cells. (C) IF was used to evaluate the impact of MCM3 knockdown on Nrf2 in Huh7 and LM3 cells ( n = 3 biologically independent experiments). (D) WB was used to measure the impact of MCM3 knockdown on HMOX-1 and NQO1 expression in Huh7 and LM3 cells, with or without THBQ. (E) WB was performed to detect the impact of MCM3 knockdown on P62, LC3B II/I, TOMM20, FUNDC1, Parkin, and PINK1 in Huh7 and LM3 cells, with or without THBQ. Data are presented as mean ± SD. ∗∗∗∗ p < 0.0001; ∗∗∗ p < 0.001; ∗∗ p < 0.01; ∗ p < 0.05, ns p ≥ 0.05. For (A), (D), and (E), statistical analysis was performed using a one-way ANOVA ( n = 3 biologically independent experiments); For B, statistical analysis was performed using a two-tailed unpaired Student’s t test ( n = 3 biologically independent experiments).

Article Snippet: Following three washes with PBS, the cells were blocked with an immunofluorescence blocking solution (Beyotime) at 37°C for 1 h. Subsequently, the cells were incubated with a primary antibody against Nrf-2 (Proteintech, #16396-1-AP, 1:50 dilution) at 4°C overnight.
