摘 要:[目的] 探讨马钱子碱对乳腺癌骨转移相关因子的影响。[方法] 建立裸鼠乳腺癌骨转移的模型,并用马钱子碱干预后用逆转录聚合酶链反应法(RT-PCR)检测各组肿瘤组织中骨转移相关因子MMP-2、CXCR4、RANKL、OPG mRNA表达量。[结果] 马钱子碱经腹腔给药的半数致死量(Medial lethal dose,LD50)为69mg/kg。根据LD50的1/10、1/20和1/40的量,设三个剂量组:高剂量组6.90mg/kg1、中剂量组3.45mg/kg和低剂量组1.73mg/kg,同时与空白对照组比较。马钱子碱各剂量组MMP-2,CXCR4,RANKL mRNA的表达量随着马钱子碱剂量的增加逐渐下降(P<0.05),而OPG mRNA的表达量则随着马钱子碱剂量的增加逐渐增加(P<0.05)。[结论] 马钱子碱可以抑制乳腺癌骨转移,主要以调节MMP-2、CXCR4、RANKL、OPG等骨转移相关因子的表达为主要手段。 |

Abstract:[Objective] To explore the effect of brucine on bone metastasis factors in breast cancer.[Methods] Model of breast cancer bone metastasis in nude mice was made,bone metastasis correlation factors expression of MMP-2,CXCR4,RANKL,OPG mRNA after Brucine intervention were detected by RT-PCR method.[Results] The median lethal dose(LD50) of brucine by intraperitoneal administration was 69mg/kg . According to LD50 and 1/10,1/20 and 1/40,the experiment group was divided into high dose group (6.90mg/kg),middle dose group(3.45mg/kg),low dose group(1.73mg/kg) and control group. The MMP-2,CXCR4,RANKL mRNA expression decreased with Brucine dose increased(P<0.05), While the expression of OPG mRNA increased with Brucine dose increased(P<0.05). [Conclusion ]Brucine can inhibit bone metastasis of breast cancer,mainly in regulating bone metastasis-associated factors such as MMP-2,CXCR4,RANKL,OPG as the main means of expression. |
