Article Title: Bacteria-responsive DNAgel system for targeted delivery of photothermally enhanced MXene/MoS 2 in the treatment of pyogenic osteomyelitis

doi: 10.1016/j.bioactmat.2025.10.023

Figure Lengend Snippet: MXMoS 2 activates Wnt signaling pathways to promote osteogenic differentiation and enhance bone regeneration. (A) GO pathway enrichment analysis of differentially expressed genes between the experimental and control groups. (B) KEGG pathway enrichment analysis of differentially expressed genes between the experimental and control groups. (C) Heatmap of inflammation-related gene expression. (D) GSEA of GO analysis in the experimental and control groups, demonstrating pathways such as osteoblast differentiation, regulation of macrophage activation, cell adhesion, positive regulation of cell migration,cell-cell junction. (E) PPI analyses identifying four distinct gene clusters (modules). (F) Bubble chart showed the various network topology metrics for the 4 modules weighted and quantified to obtain an overall score. (G) GO analysis of the genes in module 2 showed that they are associated with osteoblast differentiation and the Wnt signaling pathway. (H) Box plot of representative Wnt signaling pathway genes significantly upregulated in the MXMoS 2 group. (I) The six genes mentioned above were predicted for their upstream transcription factor regulation. (J) Schematic illustration of the mechanism of MXMoS 2 regulating macrophage polarization. (K) Representative Western blot images of WNT4 and β-Catenin expression in control group (LPS), MXMoS 2 group (LPS + MXMoS 2 ) and MXMoS 2 +siRNA group (LPS + MXMoS 2 +siRNA-WNT4). (L – M) Quantification of WNT4 and β-Catenin protein levels corresponding to (K) . ∗∗p < 0.01, ∗∗∗p < 0.001, and ∗∗∗∗p < 0.0001.
