Figure Lengend Snippet: Fig. 4 CircDLG1 promotes tumor progression by increasing the infiltration of MDSCs. a C57BL/6 mice were injected with MFC-sh-NC or MFC-sh-circDLG1 cells, and the tumor volume and tumor metastasis are shown. The mice were sacrificed at 4 weeks after injection. Left: the tumor size was measured, and the tumor volume was calculated every 4 days (n = 10 mice per group), **P < 0.05, two-way ANOVA. Right: the lungs of the mice were removed and paraffin embedded, consecutive sections (4 μm) were made and stained with hematoxylin-eosin, and the micrometastases in the lungs were examined and counted under a dissecting microscope (n = 10 mice per group), **P < 0.05, Student’s t-test. All experiments were repeated three times. Scale bar, left: 5 mm; right: 100 μm. b BALB/c nude mice were injected with MFC-sh-NC or MFC-sh-circDLG1 cells. The mice were sacrificed at 4 weeks after injection. Left: the tumor size was measured, and the tumor volume was calculated every 4 days (n = 10 mice per group). ns, no significance, two-way ANOVA. Right: The lungs of the mice were removed and paraffin embedded. Consecutive sections (4 μm) were made and stained with hematoxylin-eosin, and the micrometastases in the lungs were examined and counted under a dissecting microscope (n = 10 mice per group). ns, no significance, Student’s t-test. All experiments were repeated three times. Scale bar, left: 5 mm; right: 100 μm. c IHC analysis was performed using subcutaneous tumors for CD4, CD8, Gr-1, and CD11b (Gr-1 and CD11b are mouse MDSC markers).
