Cancer is a common cause of death worldwide. Approximately 80% of cancer patients use complementary or alternative medicines for treatment. Caffeic acid phenethyl ester (CAPE), the main active component of propolis, exhibits cytotoxic, antiproliferative and anti-cancer effects. Despite its anticancer effects CAPE exhibits no known harmful effects toward normal cells. We investigated the effects of CAPE on angiogenesis, apoptosis and oxidative stress using MDA MB-231, N2a and COLO 320 cell lines and CAPE treatments at 24 and 48 h. A two dimensional cell culture system was used and the findings were evaluated by an indirect immunohistochemical method and H-scores were calculated. CAPE was effective for all three cancer cell lines. After 24 and 48 h, we found a significant decrease in live cells and increased stress in the cells based on e-NOS and i-NOS levels.
