摘要

摘要,采用噻唑蓝(MTT)法检测不同浓度MitoQ对肝癌HepG2细胞的毒性；凋亡诱导实验研究不同浓度MitoQ对HepG2细胞凋亡率的影响；裸鼠移植瘤模型研究MitoQ对肝癌HepG2荷瘤小鼠的抑瘤作用。结果表明，MitoQ对肝癌HepG2细胞的抑制作用随着浓度而增加；给药组凋亡率显著高于对照组(,p,<,0.01)；MitoQ在1、5、10 mg/kg 剂量给药10 d后对小鼠的肿瘤生长均有抑制作用，与对照组相比，10 mg/kg剂量组肿瘤体积(,p,<,0.01)和肿瘤质量(,p,<,0.05)均有显著性差异。结果提示，MitoQ在体内体外均具有抑制肝癌HepG2细胞生长的作用。

Abstract

ABSTRACT, MTT was used to detect the celltoxicity of different concentrations of MitoQ on liver cancer HepG2 cells. Apoptosis-inducing assay was used todetect the apoptosis rate onliver cancer HepG2 cells after the treatment with varying MitoQ concentrations. Xenograft tumor model assay was used to investigate the anti-tumoreffects of MitoQ on HepG2 hepatocarcinoma-bearing mice. The results showed thatthe inhibitory effects ofMitoQ on HepG2 cells increased with MitoQ concentration,and compared with control group,the administration group apoptosis rate was significantly higher (,p,<,0.01). In nude mice xenograft tumor modelassay,the tumor growth wasall inhibited after the treatment with 1 mg/kg,5 mg/kg,and 10 mg/kg MitoQ concentration after 10 d. When the mice were treated with 10 mg/kg MitoQ,tumor volume (,p,<,0.01) and tumor mass(,p,<,0.05) were significantly different from those of the blank group (,p,<,0.01). The results indicate that MitoQ has antitumor effect ,in vivo, and ,in vitro,.
