Figure Lengend Snippet: Identification of the mechanism underlying IU1-mediated reprogramming of M2 macrophages (A and B) Verification of the efficiency of i.v. injection of clodronate liposome (Clo) in depleting TAMs of the blood (A) and the TME (B). (C and D) Statistics of tumor size monitored for 21 days in MC38 tumor-bearing mice after various indicated treatments. (E) Statistic of the percentage of CTLs in the TME after the indicated treatment. (F) Volcano plots of the differentially expressed genes between the PBS and the IU1 group. Red dots show significantly up-regulated genes in the IU1 group, and green dots show significantly down-regulated genes. (G) Heatmap illustrates the differentially expressed M1-and M2-related genes in TAMs in the IU1 group and the PBS group based on RNA sequencing results. (H) KEGG analysis identifies the 17 most enriched pathways based on the differentially expressed genes of the two groups. (I) Western blotting of p -JNK, p -ERK, p-p38, and GAPDH in IL-4/13-BMDM M2 cells treated with IU1 at the indicated time points. (J) RT-PCR to verify the typical M1/M2 polarization-related genes in M2 macrophages after treatment with IU1. (K) Flow cytometry analysis of CD206 expression on the IL-4/13-induced BMDM M2 cells from various indicated treatments. Treatments indicated: DMSO stimulation, IU1 (10 μM) stimulation, IU1 (10 μM) stimulation in the presence of inhibitors of p38 (SB203580, 10 μM), JNK (SP600125, 10 μM), Erk1/2 (U0126-EtOH, 10 μM). Statistical analysis was performed using one-way ANOVA with Tukey’s multiple comparison test. Data are presented as the mean ± SEM. ∗ p < 0.05, ∗∗ p < 0.01, and ∗∗∗ p < 0.001, and ns: not significant.
