Figure Lengend Snippet: MIIP inhibits tumor growth and metastasis and M2 macrophage infiltration in a syngeneic CRC mouse model through the STING–NFκB2–IL10 axis. (A) Tumors in situ (indicated by green arrows) and liver metastatic nodules (indicated by black arrows) were observed in a syngeneic CRC mouse model. Statistics for the size of tumors in situ (B) and the number of metastatic foci (C). (D) Statistical analysis of IL10 levels in mouse blood. (E) Representative images of HE and IHC staining for SATB2, MIIP, STING, IL10, p52, and CD163 (green arrows) in tumor tissues from the different groups. The bar graphs show the percentages of high/low STING (F), IL-10 (G), and p52 (H) expression in the different groups. (I) Comparison of the number of CD163-positive cells among the different groups. All data are presented as the means ± SDs ( n = 3). ns, not significant; * P < 0.05, ** P < 0.01, *** P < 0.001, and **** P < 0.0001; scale bar, 50 μm.
