Effects of lycopene on the cell viability of head and neck squamous cell carcinoma. (A) The dose-dependent toxicities of lycopene on FaDu and Cal27 cells at 48 h. (B) Cell survival was assessed in FaDu and Cal27 cells treated with 25 µM lycopene for 24, 48 and 72 h. (C) Colony formation was assessed in FaDu and Cal27 cells treated with THF or 25 µM lycopene, and colonies were counted. The data are presented as the mean±standard deviation (n=3; *P<0.05 and **P<0.01 compared with the THF treated cells. THF, tretrahydrofurancontaining.
