Fig. 4From: Study of the antitumor mechanisms of apiole derivatives (AP-02) from Petroselinum crispum through induction of G0/G1 phase cell cycle arrest in human COLO 205 cancer cellsDose-dependent response of the cytotoxic effects of human colon cancer and normal cells treated with AP-02. Viability of HT 29 and COLO 205 human colon cancer cells, as well as that of FHC (normal colon epithelial) cells, was evaluated after treatment with various concentrations of AP-02 (5–150 μM) for 12 h. Three samples were repeated in each group, and results are shown as the means ± SEBack to article page
