(A, B) Investigating the potential regulatory functions of DSPP in CRC by the WiKi (A) and KEGG (B) pathway enrichment analysis. (C) The mitogen-activated protein kinase (MAPK)-related pathways were enriched in CRC with high DSPP expression by GSEA analysis. (D) Western blot assays showing the expression of the FAK/ERK pathway components in HUVEC treated with CM from the indicated CRC cells (E, F) Representative tubular structures formed by HUVECs treated with indicated CM from indicated HCT8/Caco-2 cells. Data are presented as mean ± SD ( n = 3). (G) Heat map demonstrates the differentially expressed genes related to angiogenesis and matrix metalloproteinase family in HUVEC treated with CM from control and sg DSPP HCT116 cells. (H) Detecting the effect of AZD6244 on the DSPP-upregulated expression of angiogenesis and matrix metalloproteinase family-related genes by real-time quantitative PCR. Data are presented as mean ± SD ( n = 4). ∗ P < 0.05, ∗∗ P < 0.01, ∗∗∗ P < 0.001.

Figure Lengend Snippet: A schematic diagram shows the action mechanism of DSPP in regulating tumor vascular abnormalization to induce tumor metastasis. In the tumor microenvironment, IL-7F enhances the expression and secretion of DSPP in CRC. The CRC-secreted DSPP binds to the integrin α v β 3 on the endothelial cell surface and activates the downstream FAK/MAPK signaling to induce tumor vascular abnormalization, finally promote tumor metastasis.
