ABSTRACT
<p><b>OBJECTIVE</b>To investigate the inhibitory effect and mechanism against the growth of human gastric carcinoma cell line HS-746T by the combination of the survivin antisense oligonucleotide (ASODN) and P53 gene and its mechanism.</p><p><b>METHODS</b>Gastric carcinoma cell line HS-746T was treated by P53 gene and survivin antisense oligonucleotide was designed. There were four regimen groups treated by different agentsASODN alone, P53 gene alone and the combination of ASODN and P53 gene, blank control. Cell proliferative ability and cell growth were determined by cells counting and MTT. The expression of survivin mRNA and protein was detected by RT-PCR and Western blot respectively. Cell apoptotic index was detected by TUNEL.</p><p><b>RESULTS</b>ASODN alone, P53 alone and the combination of ASODN and P53 could inhibit not only the growth of gastric carcinoma cell, but also down-regulate the survivin mRNA and protein expression. The inhibitory effect was stronger, and the apoptosis index was higher in the combined transfection group than those in the other two single transfection groups.</p><p><b>CONCLUSION</b>The combination of survivin ASODN and P53 gene is more efficient to inhibit cell growth and induce apoptosis than that of agent alone.</p>
