ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the gene therapeutic efficiency of apoptosis-inducing ligand (TRAIL) related to tumor necrosis factor on human colon cancer cell line HT29.</p><p><b>METHODS</b>Human colon cancer cell line HT29 was transfected with adenovirus-mediated TRAIL gene Ad/GT-TRAIL. The morphological changes, cell growth and apoptosis were measured by phase contrast microscope, MTT method and flow cytometry.</p><p><b>RESULTS</b>Obvious morphological changes in HT29 cells was induced by Ad/GT-TRAIL and Ad/PGK-GV16. The cell suppression percentage and the percentage of apoptotic cells were 54.3% and 11.1%, respectively. When used in combination with Ad/PGK-GV16, HT29 was suppressed to 82.7% and the percentage of apoptotic cells was 24.6%. This result showed significantly enhanced therapeutic efficiency on HT29 and thus inhibiting of its growth (P < 0.05).</p><p><b>CONCLUSION</b>Ad/GT-TRAIL is able to induce apoptosis of HT29 and inhibit its growth. Ad/GT-TRAIL shows significantly enhanced therapeutic efficiency for HT29 when used in combination with Ad/PGK-GV16.</p>
