Introduction: Colorectal cancer has high mortality due to recurrent and metastatic disease. Chemotherapy is the most commonly used therapy in these cases but is not effective enough and is limited by their adverse effects and chemoresistance. Natural products are important sources of antitumor compounds. Mangiferin, a natural antioxidant glucosylxanthone, has different pharmacological properties and its anticancer potential is just beginning to be elucidated. Objective: To evaluate the in vivo antitumor activity of mangiferin in CT-26.WT murine colon carcinoma syngeneic tumor models. Methods: Three syngeneic models ectopic/subcutaneous allograf, induced lung metastasis and tumor angiogenesis in matrigel plugs were performed. Target gene specific expression analysis by quantitative PCR assay was accomplished. Results: The antitumor and antimetastatic effect was positively correlated with increasing concentration of mangiferin, achieving the greatest effect at 100 mg/kg. In the tumor angiogenesis model, macroscopic observation showed a reduction of blood supply and tumor size, and a significant reduction in hemoglobin content into matrigel plugs was obtained by quantitative analysis at both concentration of mangiferin evaluated (100 and 200 ug/mL). The antiangiogenic effect had significantly impact on decreasing weight and tumor volume. Histological analysis revealed a decreased number of blood vessels. Conclusions: Mangiferin holds promise as an effective antitumor agent by triggering antimetastatic and antiangiogenic effects. Financial Support: VLIR UOS programme Nr.
