Abstract:
目的研究特异性抗hpv16e6核酶对宫颈癌caski细胞增殖和侵袭能力的影响。方法以脂质体法将抗hpv16e6核酶、空载体质粒分别导入caski细胞,分别为caski-r和caski-p。观察细胞的生长状态,测定caski,caski-r和caski-p3种细胞的生长曲线、软琼脂克隆形成率、细胞侵袭力实验、裸鼠体内致瘤性,以及rt-pcr检测细胞中cox-2、血管内皮生长因子(vegf)的表达,同时,免疫组化检测3种细胞cox-2、vegf抗原表达,分析特异性抗hpv16e6核酶对宫颈癌caski细胞增殖和侵袭力的影响。结果caski、caski-p细胞生长速率、软琼脂克隆形成率、致瘤性和侵袭力相近,而caski-r细胞的细胞生长速率、软琼脂克隆形成率、致瘤性和侵袭力与以上两种细胞相比却明显降低。rt-pcr检测caski-r细胞的cox-2、vegf表达水平也低于caski、caski-p细胞的表达。细胞免疫组化测定caski、caski-p和caski-r细胞都有cox-2、vegf抗原表达,而caski-r细胞的抗原染色程度较弱。结论特异性抗hpv16e6核酶的导入降低了宫颈癌caski细胞的增殖和侵袭表型,可能与宫颈癌caski细胞内cox-2、vegf的表达水平降低有关。
