摘要

目的

明确槲皮素(quercetin，QUE)通过调控脂解及脂噬途径改善肝细胞脂质蓄积的效应及作用机制。

方法

利用棕榈酸(palmitic acid，PA)诱导人正常HHL-5肝细胞株(human hepatocyte cell line 5

HHL-5)建立脂肪变性肝细胞模型，使用不同浓度槲皮素(5、10、20和40 μmol/L)干预脂肪变性的HHL-5细胞24 h

实验分为(

=3)：对照组、PA组、PA+QUE5组、PA+QUE10组、PA+QUE20组、PA+QUE40组。为明确自噬对QUE作用的影响，利用3-甲基腺嘌呤(3-methyladenine，3-MA)阻断自噬，将HHL-5细胞分为(

=3)：对照组、PA组、PA+QUE40组、3-MA组、PA+3-MA组和PA+3-MA+QUE40组。2种不同实验分组均检测细胞内甘油三酯含量、脂滴蓄积情况、脂解和脂噬相关分子表达情况及共定位水平、自噬底物P62的表达水平。

结果

与对照组比较，PA组肝细胞的甘油三酯含量和脂质蓄积程度明显升高，脂解相关分子脂肪甘油三酯脂肪酶(adipose triglycerides lipase，ATGL)和比较基因识别因子58(comparative gene identification-58，CGI58)，以及脂噬相关分子Ras相关蛋白7(Ras-related protein 7

RAB7)和微管相关蛋白1B轻链3(microtubule-associated protein 1 light chain 3

LC3β)的蛋白表达水平、平均荧光强度及共定位程度均明显降低，而P62表达增强(

＜0.05)。与PA组相比，PA+QUE40组的甘油三酯含量和脂质蓄积程度显著降低，脂解和脂噬相关分子的蛋白表达水平、平均荧光强度及共定位程度也明显增加，而P62明显降低(

＜0.05)。在脂肪变性肝细胞中加入3-MA抑制自噬后，QUE对脂肪变性肝细胞的脂质蓄积的改善作用以及对脂解和脂噬相关分子的调控作用基本被抵消。

结论

槲皮素可促进脂解和脂噬途径相关分子的表达及相互作用，从而减轻脂肪变性HHL-5细胞内的脂质蓄积，但以上作用可被自噬阻断剂3-MA削弱。

Abstract

Objective

To investigate the effect and mechanism of quercetin (QUE) in improving lipid accumulation in hepatocytes by regulating lipolysis and lipophagy pathway.

Methods

The human hepatocyte cell line 5 (HHL-5) was induced by palmitic acid (PA) to establish a steatogenic hepatocyte model. Quercetin at different concentrations (5

20 and 40 μmol/L) has been utilized to interfere with HHL-5 cells for 24 h

and the experiment was divided into six groups: control group

PA group

PA+QUE5 group

PA+QUE10 group

PA+QUE20 groupand PA+QUE40 group. In order to determine the influence of lipophagy on QUE effect

3-methyladenine (3-MA) was used to block autophagy

and HHL-5 cells were divided into the control

PA+QUE40

3-MA

PA+3-MA and PA+3-MA+QUE40 groups. The contents of triglyceride (TG)

accumulations of lipid droplets

expression of lipolysis and lipophagy related molecules

and degree of co-localization

and expression level of substrate of autophagy P62 were detected in above 2 types of experimental groups.

Results

Compared with the control group

the TG content and the lipid accumulation were significantly increased

the protein levels

average fluorescence intensities and colocalization degree of lipolysis related molecules adipose triglycerides lipase(ATGL) and comparative gene identification-58(CGI58)

and lipophagy related molecules Ras-related protein 7(RAB7) and microtubule-associated protein 1 light chain 3 beta (LC3β) were significantly decreased

while the expression of P62 was enhanced in HHL-5 cells in the PA group (all

0.05). Compared with the PA group

the triglyceride content and the degree of lipid accumulation in the PA+QUE40 group were significantly decreased

and the protein expression level

average fluorescence intensity and co-localization degree of lipolysis and lipophagy related molecules were significantly increased

while P62 was significantly decreased (

0.05). When 3-MA was added to the s

teatogenic hepatocytes to inhibit autophagy

the improvement effect of QUE on lipid accumulation and the regulation of lipolysis and liphagy related molecules in steatogenic hepatocytes were neutralized.

Conclusion

QUE alleviates lipid accumulation in HHL-5 cells by promoting the expression and interaction of molecules related to lipolysis and lipophagy pathways. However

these effects can be weakened by the autophagy inhibitor 3-MA.
