Spirulina LPS suppresses the spontaneous development of mammary tumors. HER-2/neu transgenic mice were injected i.p. with Spirulina LPS (80 µg) or PBS every week between 120 and 240 days after birth. A palpable node over 5×5 mm was considered a tumor. Data represent mean ± SE of 8 mice per group. (A) Tumor incidence and (B) tumor size, expressed as summation of tumor area (width × length in mm²) of palpable nodes per mouse are depicted. *P<0.05 compared with PBS by Fischer's exact test (A), and Mann-Whitney U test (B).
