摘要

目的

探究青蒿琥酯(artesunate

ART)对3

5-二乙氧羰基-1

4-二氢-2

6-三甲吡啶(3

5-diethoxycarbonyl-1

4-dihydro-2

6-collidine

DDC)诱导的胆汁淤积性肝纤维化的作用及分子机制。

方法

将24只8周龄雄性C57BL/6J小鼠按随机数字表法分为3组：对照组(

=6)、0.1% DDC组(

=9)和0.1% DDC+ART组(

=9)。喂养含0.1% DDC的饲料2周，构建胆汁淤积小鼠模型，同时给予0.1% DDC+ART组小鼠青蒿琥酯(30.0 mg/kg，1次/d)肌肉注射。检测小鼠血清中肝损伤相关指标的水平；进行HE染色和天狼星红染色，根据Scheuer系统进行肝组织病理学评分。采用实时荧光定量PCR检测小鼠肝脏内α-SMA、Col1a1、Col1a2和Tgfβ1等表达水平，同时检测小鼠肝组织内羟脯氨酸(hydroxyproline

HYP)含量。在细胞实验中进一步探索青蒿琥酯减轻肝纤维化的机制，使用TGF-β联合ART处理LX2细胞，采用Western blot检测PI3K/Akt/mTOR信号通路相关蛋白的表达。使用ART和通路抑制剂共同处理LX2细胞后，检测肝星状细胞(hepatic stellate cell

HSC)活化标志物α-SMA的表达。

结果

青蒿琥酯给药明显减轻DDC诱导的胆汁淤积性肝损伤和肝纤维化(

0.05)，显著降低了胆汁淤积小鼠血清中ALT、AST、ALP和TBA的表达水平(

0.05)。青蒿琥酯抑制小鼠肝脏内纤维化相关指标α-SMA、Col1a1、Col1a2和Tgfβ1 mRNA的表达，并减少肝组织内HYP含量(

0.05)。青蒿琥酯可以抑制TGF-β诱导的LX2细胞内PI3K/Akt/mTOR信号通路的激活(

0.05)。PI3K/Akt/mTOR信号通路抑制剂增强青蒿琥酯对TGF-β诱导的HSC活化的抑制作用(

0.05)。

结论

青蒿琥酯能够明显改善DDC诱导的胆汁淤积性肝纤维化，它可通过调控PI3K/Akt/mTOR信号通路抑制HSC的活化，从而发挥其抗纤维化的作用。

Abstract

Objective

To explore the effect and molecular mechanism of artesunate (ART) on cholestatic liver fibrosis induced by 3

5-diethoxycarbonyl-1

4-dihydro-2

6-collidine (DDC).

Methods

8-week-old male C57BL/6J mice(

=24) were randomly divided into 3 groups: the control group(

=6)

the 0.1% DDC group(

=9) and the 0.1% DDC+ART group(

=9). Mice have been fed with diet containing 0.1% DDC for 2 weeks to establish cholestatic mouse model

and ART was given intramuscular injection (30.0 mg/kg) once a day in the 0.1% DDC+ART group. The indicators of liver injury in serum of mice were detected. HE staining and Sirius red staining were performed

and histopathological scores were obtained according to Scheuer scoring system. RT-qPCR was used to detect the levels of α-SMA

Col1a1

Col1a2 and Tgfβ1 in mouse liver. Hydroxyproline (HYP) content was detected with HYP detection kit. LX2 cells were treated with TGF-β combined with ART

and the proteins related to PI3K/Akt/mTOR pathway were detected by Western blot assay. The expression of α-SMA

hepatic stellate cell (HSC) activation marker

was detected after ART and pathway inhibitors were used to treated with LX2 cells.

Results

ART significantly ameliorated DDC-induced cholestatic liver injury and liver fibrosis (

0.05). ART markedly decreased the levels of ALT

AST

ALP and TBA in serum of mice (

0.05). ART inhibited the mRNA expression of α-SMA

Col1a1

Col1a2 and Tgfβ1

and reduced the content of HYP in liver tissues of mice with cholestasis(

0.05). In addition

ART obviously inhibited TGF-β-induced activation of PI3K/Akt/mTOR pathway in LX2 cells (

0.05). PI3K/Akt/mTOR signaling pathway inhibitors enhanced the inhibitory effect of HSC activation induced by TGF-β(

0.05).

Conclusion

ART observably improves DDC-induced cholestatic liver fibrosis

and it can inhibit HSC activation by regulating PI3K/Akt/mTOR signaling pathway

thus exerting anti-fibrosis effect.
