Figure Lengend Snippet: TAMpep-IP suppresses tumor growth in the colon cancer model. (A) BALB/c mice were subcutaneously inoculated with CT26 colon carcinoma cells (3 × 10 5 cells per mouse). Starting on day 7 post-inoculation, TAMpep-IP (400 nmol/kg) was administered subcutaneously every three days for a total of seven doses. (B) Representative images of tumors excised at the experimental endpoint (day 25) showed visibly reduced tumor size in the TAMpep-IP–treated group compared to control. (C) Tumor volumes were measured every 3 days following tumor implantation. Mice treated with TAMpep-IP exhibited significantly reduced tumor growth relative to the control group (control: n = 6; TAMpep-IP: n = 6). (D) Tumor proliferation was evaluated by immunohistochemical staining of Ki-67 in tumor sections. Quantitative analysis showed a significantly lower proportion of Ki-67 + proliferating cells in TAMpep-IP–treated tumors. Representative immunohistochemistry images were acquired at ×100 magnification. Scale bar = 1000 μm. All data are presented as mean ± SEM. *p<0.05, ***p<0.001.

Figure Lengend Snippet: TAMpep-IP reduces M2 macrophages in tumor tissues of colon cancer model. (A) Tumor-infiltrating immune cells were isolated from CT26 tumors in control and TAMpep-IP–treated mice. Flow cytometry was used to identify CD206 + F4/80 + macrophages within the CD45 + CD11b + population. TAMpep-IP significantly decreased the proportion of M2-like tumor-associated macrophages. (B) Quantitative RT-PCR analysis of tumor tissues revealed that TGF-β mRNA expression, a key M2-associated cytokine, was significantly reduced in TAMpep-IP–treated tumors compared to controls. (C) Western blot analysis of tumor showed a marked decrease in CD206 protein levels following TAMpep-IP, indicating effective suppression of M2 macrophage markers. (D) CD206 + macrophages were further visualized by immunohistochemical staining of tumor sections. ImageJ-based quantification confirmed a significant reduction in CD206 + area in TAMpep-IP–treated tumors. Representative immunohistochemistry images were acquired at ×100 magnification.

Figure Lengend Snippet: TAMpep-IP enhances inflammatory cytokine expression and activated CD8 + T cells in tumor tissues of colon cancer model. (A) Flow cytometry was used to evaluate CD8 + T cell function in CT26 tumor tissues from control and TAMpep-IP-treated mice. TAMpep-IP significantly increased the proportion of activated Granzyme B + CD8 + T cells, while reducing the frequency of exhausted Tim-3 + CD8 + T cells, indicating enhanced cytotoxic T cell activity. (B, C) Confocal immunofluorescence analysis was performed on tumor sections stained with DAPI (nuclei), anti-CD8 (green), anti-Granzyme B (red), and anti-PD-1 (red). Activated CD8 + T cells were identified by co-localization of CD8 and Granzyme B, whereas exhausted CD8 + T cells were identified by co-localization of CD8 and PD-1. Quantification revealed a significant increase in intertumoral CD8 + Granzyme B + T cells and a concomitant decrease in CD8 + PD-1 + exhausted T cells following TAMpep-IP. Representative confocal images were acquired using a 40× objective lens. Scale bar = 20 μm. (D) Quantitative RT-PCR analysis of CT26 tumor tissues showed significantly elevated mRNA levels of pro-inflammatory cytokines TNF-α, IL-1β, and IL-12 in TAMpep-IP–treated mice compared to controls, indicating induction of a pro-inflammatory tumor microenvironment. All data are presented as mean ± SEM. *p<0.05, **p<0.01, ***p<0.001, ****p < 0.0001.
