Fig. 8From: Antiproliferation of Cryptocarya concinna-derived cryptocaryone against oral cancer cells involving apoptosis, oxidative stress, and DNA damageSchematic diagram of hypothesized mechanism of CPC-induced cell killing of human oral cancer cells. Changes in oral cancer cells (Ca9-22) are indicated by bold arrows, such as increases of oxidative stress, apoptosis, DNA damage, and cell death. The upward arrows indicate the increase in each assay of this study. Different assays were shown in parentheses. The bold arrow with “?” symbol is not examined in this studyBack to article page
