Abstract

During the recent years, much great deal of research has been conducted on potential use of certain herbs and nutraceuticals to manage nonalcoholic fatty liver disease (NAFLD), specifically with those strong biological activities and antioxidant ability. In our research, the goal is to investigation the protective efficacy of the ethanol extract of Crataegus orientalis fruits (COE) aganist lipid accumulation in oleic acid (OA)-induced hepatocellular carcinoma cells (HepG2) at the molecular level. Firstly, antioxidant activity and lipoxygenase activity of the C. orientalis were determined in vitro. For induction of lipid accumulation in HepG2, we established an in vitro model using 1 mM OA. The C. orientalis was evaluated for their ability to prevent from lipid accumulation and effects on sterol regulatory element binding protein-1c (SREBP-1c), acetyl CoA carboxylase (ACC1) and fatty acid synthase (FAS) mRNA levels involved in lipid metabolism. The C. orientalis exhibited moderate antioxidant activity against ABTS and DPPH radicals and a significant anti-inflammatory effect against the 5-lipoxygenase enzyme. The results demonstrated that the COE (100 µg/ml) inhibited lipid accumulation (p < 0.01) and was effective in reducing triglyceride (TG) concentration (p < 0.001) and production of reactive oxygen species (ROS) in HepG2 cells (p < 0.05). C. orientalis suppressed mRNA expression of lipid metabolism enzymes (ACC1, FAS) and transcription factor SREBP-1c (p < 0.001, p < 0.001 and p < 0.01, respectively). Our findings recommend that C. orientalis fruits are potentially protective against lipid accumulation in hepatocytes and may have beneficial effects in the treatment of the NAFLD.

山楂果提取物对油酸诱导的 HepG2 细胞脂质积累的影响
近年来,人们对某些草药和营养保健品在控制非酒精性脂肪肝(NAFLD)方面的潜在用途进行了大量研究,特别是那些具有较强生物活性和抗氧化能力的草药和营养保健品。我们的研究旨在从分子水平研究山楂果实乙醇提取物(COE)对油酸(OA)诱导的肝癌细胞(HepG2)脂质积累的保护作用。首先,在体外测定了东方草果的抗氧化活性和脂氧合酶活性。为了诱导 HepG2 中的脂质积累,我们使用 1 mM OA 建立了一个体外模型。我们评估了东方草防止脂质积累的能力,以及对参与脂质代谢的甾醇调节元件结合蛋白-1c(SREBP-1c)、乙酰辅酶羧化酶(ACC1)和脂肪酸合成酶(FAS)mRNA水平的影响。东方草对 ABTS 和 DPPH 自由基具有中等程度的抗氧化活性,对 5-脂氧合酶具有显著的抗炎作用。结果表明,COE(100 µg/ml)能抑制脂质积累(p <0.01),并能有效降低甘油三酯(TG)浓度(p <0.001)和 HepG2 细胞中活性氧(ROS)的产生(p <0.05)。东革阿里抑制脂质代谢酶(ACC1、FAS)和转录因子 SREBP-1c 的 mRNA 表达(分别为 p < 0.001、p < 0.001 和 p < 0.01)。我们的研究结果表明,东方草果对肝细胞中的脂质积累具有潜在的保护作用,可能对治疗非酒精性脂肪肝有好处。
