Figure Lengend Snippet: SERPINE2 is positively correlated with M2 macrophage infiltration in COAD. (A) Scatter plot showing the correlation of 6 different immune cell types and SERPINE2 expression (p < 0.05). The black line in each plot is a fitted linear model indicating the proportion of tropism of the immune cell along with SERPINE2 expression, and the Pearson coefficient was used for the correlation test. (B) Scatter plot showing the correlation of CD68+ Marcophage and SERPINE2 expression (p < 0.05). C.Scatter plot showing the correlation of M1/M2 macrophage and SERPINE2 expression (p < 0.05). The blue line in each plot is a fitted linear model indicating the proportion of tropism of the immune cell along with SERPINE2 expression, and the Pearson coefficient was used for the correlation test.

Figure Lengend Snippet: SERPINE2 is associated with infiltration of CD68 macrophage in COAD patients. (A) The expression of SEPRINE2 in patient tissues was detected by IHC. Adjacent tissue not expressing SERPINE2; tumor tissue strongly expressing SERPINE2. (B) Scatterplot showing the correlation between SERPINE2 and CD68 expression (p < 0.05). The blue line in each plot is a fitted linear model indicating the relationship between SERPINE2 and CD68 expression. (C) The expression of SERPINE2 and CD68 in patient tissues were detected by IHC. High levels of SERPINE2 expression are associated with increased expression of CD68. (* p<0.05, **p<0.01, *** p<0.001).

Figure Lengend Snippet: The external secretion of SERPINE2 from colorectal cancer cells promotes macrophage polarization to accelerate the development of colorectal cancer. (A) Schema diagram showing that THP-1 cells were treated with PMA, followed by the treatment of SERPINE2 recombinant protein as indicated treatments to obtain activated macrophages. Then tumor cells cocultured with these macrophages. were used to subsequent experiments. (B, C) RT-qPCR and Westen blot displayed SERPINE2 mRNA and Protein expression were upregulated in colorectal cancer cells. (D) The secretion of SERPINE2 in colorectal cancer cells was detected by ELISA. (E) The effect of SERPINE2 recombinant protein on macrophage polarization. (F) RT-qPCR displayed conditioned medium (CM) derived from colorectal cancer cells promotes the upregulation of macrophage M2 markers, compared to normal Intestinal cells. (G) ELISA analysis demonstrated that SERPINE2 secretion was significantly reduced after SERPINE2 knockdown. (H) RT-qPCR displayed conditioned medium with SERPINE2 knockdown down-regulated macrophage M2 markers. (I, J) The conditioned medium from macrophages treated with SERPINE2 recombinant protein promoted cancer cell proliferation (measured by CCK-8 assay) and migration (assessed by Transwell assay. (*p<0.05, **p<0.01, ***p<0.001).
