Effect of AFP antisense [S] ODNs on the in vivo induction of apoptosis. Representative fluorescence-activated cell sorter analysis of DNA content (propidium iodide fluorescence) in untreated (A), 2 mg antisense (B), 4 mg antisense (C), 2 mg sense (D) and 4 mg sense [S] ODN (E)-treated SMMC-7721 hepatoma cells. Apoptosis analysis of the cells was done by using tumor xenografts of nude mice treated with [S] ODNs for 8 days. Percentages indicate the proportion of cell population with a subdiploid DNA content.
