This study aimed at evaluating the cytoprotective activity of jujube water extract (JWE) against alcohol-induced oxidative stress via the activation of the Nrf2 pathway in HepG2 cells. JWE had various phenolic compounds, and the vanillic acid content was the highest in the extract. To determine the cytoprotective effect of JWE against alcohol-induced damage, hepatocytes were treated with JWE and 3% ethanol. JWE (100 g/mL) markedly increased cell viability by approximately 100% in a dose-dependent manner. Moreover, JWE attenuated the production of malondialdehyde, reactive oxygen species, aspartate, and alanine aminotransferase and the depletion of glutathione. Moreover, JWE enhanced the expression of antioxidant defense enzymes including heme oxygenase-1, NADPH quinone oxidoreductase 1, and -glutamate-cysteine ligase catalytic against alcohol-induced oxidative damage in hepatocytes via the activation of Nrf2. Taken together, JWE possesses the protective effect against alcohol-induced oxidative injury in hepatocytes through the upregulation of the Nrf2 signaling pathway. Therefore, jujube fruit might have the potential to improve alcohol-related liver problems.
本研究旨在通过激活HepG2细胞中的Nrf2途径,评估枣水提取物(JWE)对酒精诱导的氧化应激的细胞保护活性。JWE含有多种酚类化合物,其中香草酸含量在提取物中最高。为了确定JWE对酒精诱导损伤的细胞保护作用,用JWE和3%乙醇处理肝细胞。JWE(100μg/mL)以剂量依赖性方式显著提高细胞活力约100%。此外,JWE减轻了丙二醛、活性氧、天冬氨酸和丙氨酸转氨酶的产生以及谷胱甘肽的消耗。此外,JWE通过激活Nrf2增强了抗氧化防御酶的表达,包括血红素加氧酶-1、NADPH醌氧化还原酶1和γ-谷氨酸半胱氨酸连接酶催化亚基,以对抗酒精诱导的肝细胞氧化损伤。综上所述,JWE通过上调Nrf2信号通路对酒精诱导的肝细胞氧化损伤具有保护作用。因此,枣果可能具有改善酒精相关肝脏问题的潜力。
