DNTT and colonic neoplasm: To determine whether the inhibition of cell growth by the (E)-4-(3-(3,5-dimethoxyphenyl)allyl)-2-methoxyphenol was due to the induction of apoptosis, we evaluated the changes in colon cancer cells by using 4,6-diamidino-2-phenylindole (DAPI) staining followed by TdT-mediated dUTP nick and labeling (TUNEL) assays, and then the double labeled cells were analyzed by fluorescence microscope.
