Figure Legend Snippet: (A) Viability of NHDF cells exposed to different concentrations of GO-Se as determined by MTT assay. (a); 24 h, (b); 48 h, (c); 72 h. Control cells were assigned 100 % viability. The experiments were conducted in quadruplicate (n = 4), and the data are expressed as median ± IQR. ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001, ∗∗∗∗p < 0.0001 by Kruskal–Wallis test with Dunn's Multiple comparison test. (B) IC 50 of GO-Se in NHDF cells at 24 h, 48 h, and 72 h.
Techniques Used: MTT Assay, Control, Comparison
Figure Legend Snippet: Panels A , B , and C depict apoptotic morphological changes observed at 24 h, 48 h and 72 h, respectively, using AO/EtBr staining and fluorescence microscopy (10 × ). NHDF cells were treated with GO-Se at sub-IC 50 (200 μg mL −1 for 24 h, 150 μg mL −1 for 48 h, and 75 μg mL −1 for 72 h), IC 50 (275 μg mL −1 for 24 h, 163 μg mL −1 for 48 h, and 110 μg mL −1 for 72 h), and supra-IC 50 (400 μg mL −1 for 24 h, 300 μg mL −1 for 48 h, and 200 μg mL −1 for 72 h) doses at each respective time point. Data represent three independent experiments (n = 3). The yellow arrows represented cells exposed to supra-IC 50 concentrations exhibited extensive nuclear condensation, chromatin fragmentation, and apoptotic body formation. Scale bar: 200 μm.

Techniques Used: Staining, Fluorescence, Microscopy
Figure Legend Snippet: (A) Fluorescence microscopy images (10 × ) showing ROS levels in control and GO-Se-treated NHDF cells at the IC 50 dose after 24 h, 48 h, and 72 h. a) Control, b) 24 h: IC 50 dose 275 μg mL −1 , c) 48 h: IC 50 dose 163 μg mL −1 , and d) 72 h: IC 50 dose 110 μg mL −1 . H 2 O 2 : positive control. Scale bar, 100 μm. (B) Flow cytometry analysis of ROS production in NHDF cells treated with GO-Se for 24 h, 48 h, and 72 h. Flow cytometry analysis of ROS production was normalized to untreated controls. Assay responsiveness was confirmed in the microscopy arm with H 2 O 2 as a positive control. The bar graph presents the quantification of H 2 DCFDA fluorescence intensity in NHDF cells treated with GO-Se. Data are expressed as median ± IQR from three independent (n = 3) experiments by one-way ANOVA followed by Tukey's multiple comparisons test: ∗p < 0.05, ∗∗p < 0.01 vs. control.

Figure Legend Snippet: (A) An in vitro wound healing model was used to examine the effect of GO-Se on NHDF cell migration. W 0 : wound area at 0 h (μm 2 ). Wt 24 , Wt 48 , and Wt 72 : wound area at 24 h, 48 h, and 72 h, respectively. Scale bar, 100 μm.

(A) Antibody array layout showing antigen-specific antibody spots; “nbs1” control spots were used for data normalization, and “NEG” spots served as negative controls for baseline signal measurement. (B) Representative images of the original antibody arrays. (C) Heat map illustrating the relative expression levels of DDR-related proteins, with color intensity indicating normalized expression values. Data represent four independent experiments (n = 4). (D) Semi-quantitative analysis of DDR-related proteins expression using antibody microarray in NHDF cells treated with GO-Se at 275 μg mL −1 for 24 h.

Figure Legend Snippet: Expression profiles of cytokine-related factors in NHDF cells following 24 h treatment with GO-Se at 275 μg mL −1 . A human cytokine antibody array containing 40 cytokines was used, with “POS” positive control spots applied for data normalization. (A) Each antibody was spotted in quadruplicate in a horizontal layout. (B) Representative fluorescence images of the cytokine antibody arrays. (C) Upregulated cytokines identified in NHDF cells treated with GO-Se (275 μg mL −1 , 24 h). The array detected nine significantly upregulated cytokines compared to control cells, including chemokines, metalloproteinase, interleukins/receptors, and macrophage inflammatory protein. (D) Downregulated cytokines identified in GO-Se–treated NHDF cells. Six cytokines were significantly downregulated, comprising adhesion receptor, metalloproteinase, interleukins/, macrophage inflammatory protein, and colony-stimulating factor. Data represent four independent experiments (n = 4). Statistical analysis was performed using an unpaired Student's t-test. ∗∗p < 0.01, ∗∗∗p < 0.005, ∗∗∗∗p < 0.0001 vs. control.
