Figure 4: Lycopene potently inhibited LNCaPp prostatic carcinoma growth in vivo. (a) Tumor sizes were detected in LNCaP prostatic carcinoma mice model with the treatment of different concentration (0, 1, 5, and 10 mg kg−1) of lycopene by gavage for 1 week while all the mice were still survival but sick. Tumor sizes were determined in the three (b) LNCaP, (c) PC3, and (d) DU145 tumors. Values are mean and standard deviation from at least three independent experiments in duplicate. *P < 0.01, groups treated with lycopene versus control (0 mg kg-1).
