C57BL/6 mice received intrasplenic injections of mouse colorectal cancer cells (MC38). Mice were subsequently treated with IgG control (IgG; n = 6), anti-Ly6G antibody (anti-Ly6G; n = 6), or anti-Ly6G plus anti-CD8a antibodies (anti-Ly6G + anti-CD8a; n = 6). Livers were harvested on day 14. N, Representative images of liver metastases from IgG, anti-Ly6G, and anti-Ly6G + anti-CD8a groups. O, Comparison of liver weights among the three groups. P values were calculated by the Wilcoxon rank-sum test ( B and L ) and unpaired Student t test ( F , K , and O ). *, P < 0.05; **, P < 0.01; ***, P < 0.001. CRC, colorectal cancer; Ctrl, control.

Article Title: UPF1-dependent glycolysis driven by LINC00887 facilitates macrophage M2 polarization in clear cell renal cell carcinoma

doi: 10.3389/fimmu.2026.1833383

Figure Lengend Snippet: Overexpression of UPF1 in ccRCC inhibits M2 macrophage polarization and enhances the tumor suppressor function of CD8 + T cells, Caki-1 cell groups of sh-NC+PBS, sh-UPF1+PBS, or sh-UPF1 + 2-DG, and the conditioned medium was used to culture and polarize M0 macrophages. The polarized macrophages were cultured with activated CD8 + T cells. (A) CFSE assessed CD8 + T cell proliferative capacity. (B) Flow cytometry measured apoptosis rate of CD8 + T cells in different co-culture systems. (C) CD8 + T cells from culture systems were co-cultured with normal Caki-1 cells, with LDH assays determining cytotoxic effect of CD8 + T cells. *, p < 0.05. cRCC, Clear cell renal cell carcinoma; UPF1, Up-frameshift protein 1; 2-DG, 2-Deoxy-D-glucose; CFSE, Carboxyfluorescein succinimidyl ester.
