目的:
2
研究藤茶总黄酮(TF)对肝癌裸鼠移植瘤的抑制作用,预测其作用机制可能与调控细胞凋亡肌醇磷脂-3-激酶/蛋白激酶B/p53(PI3K/Akt/p53)通路的相关因子有关。
方法:
2
建立BEL-7404肝癌裸鼠移植瘤模型,实验分为模型组,5-氟尿嘧啶(5-FU,1.0 g·L
-1
)组及TF高、中、低质量浓度(30,15,7.5 g·L
-1
)组,给药干预2周后处死裸鼠,剥离出瘤组织,根据瘤重和瘤体积计算抑瘤率(IR)及相对肿瘤增殖率(T/C);采用逆转录聚合酶链式反应(RT-PCR)检测PI3K/Akt/p53中相关基因胞内PI3K,Akt1,p53,半胱氨酸天冬氨酸蛋白酶-3(Caspase-3),B细胞淋巴瘤/白血病-2(Bcl-2),Bcl-2相关X蛋白(Bax) mRNA表达;采用免疫组化检测相关蛋白PI3K,Akt1,p53,Caspase-3,Bcl-2,Bax蛋白的表达。
结果:
2
TF高、中、低质量浓度组IR分别为53.26%,35.94%,26.74%,T/C分别为59.74%,69.66%,84.82%;逆转录聚合本科链式反应(RT-PCR)表明,与模型组比较,TF 30 g·L
-1
能明显下调PI3K,Akt1,Bcl-2 mRNA表达,显著上调抑癌基因p53,Capsase-3,Bax mRNA表达;免疫组化表明,与模型组比较,TF 30,15 g·L
-1
均明显下调PI3K,Akt1,Bcl-2蛋白的表达,显著上调p53,Capsase-3,Bax蛋白的表达。
结论:
2
TF有明显的体内抗肝癌活性,其机制可能与上调p53,Caspase-3的表达,激活细胞凋亡PI3K/Akt/p53通路,从而抑制Bcl-2,提高Bax的表达,促进肝癌细胞凋亡有关。
Objective:
2
To study inhibitory effect of total flavonoids from
Ampelopsis grossedentata
(TF) on transplanted tumors of human hepatocellular carcinoma in nude mice
and predict that its mechanism may be related to relevant factors regulating phosphatidylinositol 3 kinase (PI3K)/protein kinases B(Akt)/p53 pathway in apoptosis.
Method:
2
The nude mice transplanted BEL-7404 hepatoma model was established and divided into model group
5-fluorouracil (5-FU) group (1.0 g·L
-1
) and TF (30
15
7.5 g·L
-1
) groups. Nude mice were put to death after two weeks of administration. The tumor tissues were excised
and tumor inhibition rate (IR) and relative tumor proliferation rate (T/C) were calculated. Reverse transcription PCR(RT-PCR) was used to detect PI3K
Akt1
p53 gene(p53)
Caspase-3
B cell lymphoma/lewkmia-2 (Bcl-2)
Bcl-2 associated X protein (Bax) mRNA expressions
immunohistochemical method was used to detect expressions of relevant proteins PI3K
Akt1
p53
Caspase-3
Bcl-2
Bax.
Result:
2
The establishment of xenograft tumor in mice showed that TF was administered orally once per day for two consecutive weeks. IRs were 53.26%
35.94%
and 26.74%
respectively. T/Cs were 59.74%
69.66%
and 84.82%
respectively. RT-PCR experiments showed that compared with model group
when TF concentration was 30 g·L
-1
mRNA expressions of PI3K
Akt1
and Bcl-2 were significantly down-regulated
and mRNA expressions of tumor suppressor genes p53
Capsase-3
and Bax were significantly up-regulated. Immunohistochemical method results showed that compared with model group
at TF concentrations of 30
15 g·L
-1
all PI3K
Akt1
Bcl-2 protein expressions were significantly down-regulated
while p53
Capsase-3
Bax protein expressions were significantly increased.
Conclusion:
2
TF has an obvious anti-liver cancer activity
in vivo
. Its mechanism may be correlated with up-regulation of expressions of p53
Caspase-3
and activation of apoptosis PI3K/Akt/p53 pathway
thereby inhibiting Bcl-2
increasing expression of Bax
and promoting hepatocellular apoptosis.
