Figure 3: Lycopene potently prolonged the survival time of prostatic carcinoma mice model in vivo. There prostatic carcinoma cell lines ([a] LNCaP, [b] PC3, and [c] DU145 cells) were injected with 1 × 105 cells into the left foreleg in mice. Then the model mice were treated with different concentration (0, 1, 5, or 10 mg kg−1) of lycopene by gavage once per day for 7 days and the survival was monitored to up to 180 days. The survival time was calculated after each mouse was dead suffering sick, moribund and skinny (n = 10). P < 0.001, groups treated with lycopene versus control (0 mg kg-1).
