Figure Lengend Snippet: Analysis of periostin expression. (a) Schematic representations of periostin expression analysis. Gene expression under (b) 21 % p O 2 condition and (c) 5 % p O 2 condition (qRT-PCR). (d) Immunofluorescence staining of periostin. (e) Protein expression (ELISA) analysis. (f) Volcano plot comparing FBs under hypoxia without IL-4 (down – blue) and hypoxia with IL-4 (up – red). Labeled genes are those known to be associated with AD pathogenesis and meet the DEG criteria (padj < 0.05 & log2FC > 0). (g) Normalized expression heatmap of selected genes associated with AD pathogenesis. Data are presented as the mean ± s.d. (b, c, e) (n = 3–5). Statistical significance and p values are determined by one-way ANOVA with Tukey's post-hoc comparison (b, c) and unpaired two-tailed Student's t-test (e). (∗) indicates a significant difference (∗p < 0.05, ∗∗p < 0.01, ∗∗∗∗p < 0.0001). (N.D.; Not detected).

(B-C) Representative Western blot (B) and densitometry normalized to GAPDH and Ctrl (C) of Periostin across 6 biological replicates. (D-E) Representative Western blots for α-SMA (D) and densitometric quantification (E) following treatment with p38 MAPK inhibitor SB203580 (10 μM). (F-G) Representative Western blots for periosotin (F) and densitometric quantification (G) following treatment with p38 MAPK inhibitor SB203580 (10 μM). (H) Total soluble collagen secretion measured by Picrosirius Red. Data are mean ± SEM. Statistical significance was determined by one-way ANOVA or two-way ANOVA as appropriate.
