ABSTRACT
<p><b>OBJECTIVE</b>To examine the relationship between NF-kappaB signal transduction way and the sensitivity of Tca8113 carcinoma cell to Pingyangmycin chemotherapy.</p><p><b>METHODS</b>2 mg/L antisense p65 oligodeoxynucle-otides (5'-GAACAGTTCGTCCATGGCCG-3') was transfected into Tca8113 cells through Lepofectin vectin, then the cells were treated with 8 mg/L Pingyangmycin. After 3 h and 6 h, the expression of p65 in nucleus was studied with immunohistochemical methods and Western blot analyses. After 48 h, the inhibitory rate of cell growth was detected with MTT assay.</p><p><b>RESULTS</b>The NF-kappaB/p65 signal transduction way in Tca8113 cells was activated after treated with Pingyangmycin. But the transfection of antisense p65 oligodeoxynucle-otides inhibited the activation of the signal transduction, the p65 expression in nucleus was decreased significantly (P < 0.05) at 6 h, and the inhibitory rate of cell growth was increased significantly (P < 0.05) at 48 h.</p><p><b>CONCLUSION</b>The results suggested the chemotherapeutic sensitivity of Tca8113 carcinoma cell to Pingyangmycin was improved by the inhibition of NF-kappaB/p65 signal transduction.</p>
