ABSTRACT
<p><b>BACKGROUND</b>To construct a DC-Ad-Ki-ras(V12) vaccine and investigate the anti-tumor activities of lung cancer dendritic cell vaccine modified by mutant Ki-ras gene in vitro.</p><p><b>METHODS</b>Ki-ras(V12) cDNA was transfected into cultured bone marrow-derived DC with the recombinant adenovirus [(Ad-Ki-ras(V12)] containing human mutant Ki-ras gene. Anti-tumor activity of the vaccine was studied in vitro by flow cytometry, PCR, MLR and cytotoxicity assay.</p><p><b>RESULTS</b>(1) The DC vaccine was confirmed not only to express Ki-ras(V12) gene, but also to remarkably stimulate lymphocyte proliferation and improve CTL activity. (2) The DC vaccine modified by mutant Ki-ras gene could induce specifical CTL activity of immunized mice against Lewis lung carcinoma that could express Ki-ras(V12) gene, but not to B16.</p><p><b>CONCLUSIONS</b>The DC vaccine modified by mutant Ki-ras gene can induce obvious anti-tumor activities against Lewis lung carcinoma that can express Ki-ras(V12) gene.</p>
