摘 要:目的:探讨腺病毒载体介导的p53基因(AD-p53)对人卵巢浆液性乳头状腺癌细胞系(SKOV-3)的影响,探讨AD-p53及联合顺铂(DDP)以及不同剂量的AD-p53对卵巢癌裸鼠腹腔移植瘤及腹水的抑制作用。方法:培养SKOV-3细胞,分组后行免疫荧光染色,绘制细胞生长曲线;建立裸鼠腹腔移植瘤模型。共6组:空白对照组、DDP组、低AD-p53组、高AD-p53组、低AD-p53+DDP组、高AD-p53+DDP组。计算抑瘤率及裸鼠腹水形成量。结果:①成功转染基因并表达p53蛋白的细胞在染色后呈红光,当MOI=100及以上时,转染率可达90%以上。②体外实验结果:经AD-p53作用的各组,细胞生长曲线受到不同程度抑制。③体内试验结果:a:各治疗组与空白对照组、联合用药组与单用药组之间瘤重差异均有统计学意义(P﹤0.05),DDP组与单用AD-p53组、不同剂量AD-p53组之间瘤重差异无统计学意义(P>0.05)。b:空白对照组裸鼠均出现血性腹水,量0.4~2.0ml,各治疗组无明显腹水形成。高AD-p53组荷瘤裸鼠的一般状态较其他组差。结论:AD-p53可成功转染SKOV-3细胞,并对细胞生长有抑制作用;AD-p53能抑制卵巢癌裸鼠腹腔移植瘤,并对腹水的形成有抑制作用,其与顺铂有协同抗癌性;无限制地增大AD-p53剂量不会增加疗效,反而会对用药个体不利。Objective:To investigate the effects of AD-p53 on human ovarian cancer SKOV-3 cells and the effects of single use of AD-p53, AD-p53 combined with cisplatin and different doses of AD-p53 on the treatment of intraperitoneal transplanted ovarian tumor and ascites in nude mice. Methods:The human ovarian cancer SKOV-3 cells were cultured, stained by immunofluorescence, and cell growth curve was drawn. Intraperitoneal transplanted ovarian tumor in nude mice were established and divided into six groups: blank control group, DDP group, low AD-p53 group, high AD-p53group, low AD-p53 + DDP group, and high AD- p53 + DDP group. The tumor inhibit rate and the volume of ascites was calculated. Results :(1) The SKOV-3 cells which transfected genes and expressed p53 protein were stained red. When MOI ≥100, the transfection rate was over 90%. (2) The results of the experiment in vitro showed that the cell growth curve in each group was inhibited in different degree by the role of AD-p53. (3) The results of the experiment in vivo showed that there was statistic difference in the tumor weight among all of the treatment groups and blank control group, single-drug therapy groups and combination therapy groups ( P 〈0.05). There was no statistic difference in the tumor weight among DDP group and single use of AD-p53 group, different doses of AD-p53 groups( P〉 0.05). All of the treatment groups didn't have ascited formed while the blank control group had. The volume of ascites was 0.4 - 2.0 ml. The general condition in the high-dose tumor-bearing nude mice was worse than that in the other groups. Conclusions:AD-p53 can be transfected into SKOV-3 cells successfully, and can inhibit cell growth significantly. AD-p53 can inhibit intraperitoneal transplanted ovarian cancer cells growth and ascites formation. AD-p53 combined with DDP has synergetic cancer inhibition effects, however, dose augmentation without limitation won't increase its effect besides harmful to the body.
