目的 　探討5-氟尿嘧啶(5-FU)和柳氮磺胺吡啶(sulfasalazine, SZ)對(duì)裸鼠皮下移植瘤胰腺癌細(xì)胞BxPC-3凋亡基因的作用。
方法 　用RT-PCR和Western blot法分別檢測(cè)5-FU及SZ單獨(dú)或聯(lián)合作用后裸鼠皮下移植瘤凋亡相關(guān)基因NF-κB (p65)、bcl-2及cyclinD1 mRNA和蛋白表達(dá)水平以及Bax蛋白表達(dá)水平的變化。
結(jié)果 　5-FU (7.5和15 mg/kg)和SZ(10和20 mg/kg)單獨(dú)或聯(lián)合作用裸鼠皮下移植瘤，其N(xiāo)F-κB (p65) mRNA表達(dá)相對(duì)含量和蛋白表達(dá)水平與各自對(duì)照組比較，除SZ組2個(gè)亞組外，其余各組均明顯降低（P＜0.01）； bcl-2和cyclinD1 在mRNA和蛋白水平以及Bax蛋白表達(dá)量與各自對(duì)照組比較差異均有統(tǒng)計(jì)學(xué)意義（P＜0.01）； 上述指標(biāo)經(jīng)多因素方差分析顯示二者間有明顯的交互作用。
結(jié)論 　Bax水平上調(diào), bcl-2、cyclinD1及NF-κB (p65)水平下調(diào)可能是SZ可協(xié)同增強(qiáng)5-FU誘導(dǎo)裸鼠皮下移植瘤胰腺癌細(xì)胞BxPC-3凋亡的機(jī)理之一。
