海马(Hippocampus kuda Bleeler)是水产养殖中的代表性海洋物种,具有特殊的药用和食品价值。在本研究中,研究了海马水解物中的两种肽(SHP-1 和 SHP-2)对 HepG2/CYP2E1 细胞中乙醇介导的氧化应激的保护作用。首先,SHP-1和SHP-2没有表现出细胞毒性。与乙醇处理组相比,SHP-1和SHP-2以浓度依赖性方式增加细胞活力。其次,SHP-1和SHP-2显着降低细胞内活性氧(ROS)的产生、γ-谷氨酰转肽酶(GGT)活性和肿瘤坏死因子-α(TNF-α)水平,并显着增强超氧化物歧化酶(SOD)和谷胱甘肽(GSH)活性。 SHP-1 和 SHP-2 还下调 GGT、bax、c-caspase-8/-9/-3、p-Akt、p-IκB-α、p-p65、p-ERK 和 p-p38 的表达,但上调 SOD、GSH、NF-E2 相关因子 2 (Nrf2)、血红素加氧酶-1 (HO-1) 和 bcl-2 水平,如 Western 研究所示印迹分析。此外,SHP-1和SHP-2增加了线粒体膜电位(MMP),减少了DNA损伤,并抑制了p65的核转位。这些结果表明,海马水解物中的两种肽可以被认为是一种潜在的功能性生物材料,并进一步提高海马在水产养殖中的使用价值。海马水解物中的两种肽可以被认为是一种潜在的功能性生物材料,并进一步提高海马在水产养殖中的使用价值。
Seahorse (Hippocampus kuda Bleeler) are representative marine species in aquaculture, with special value of medicine and food. In this study, the protective effects of two peptides from seahorse hydrolysates (SHP‐1 and SHP‐2) against ethanol‐mediated oxidative stress in HepG2/CYP2E1 cells were investigated. Firstly, SHP‐1 and SHP‐2 presented no cytotoxicity. Compared with the ethanol‐treated groups, SHP‐1 and SHP‐2 increased cell viability in a concentration‐dependent manner. Secondly, SHP‐1 and SHP‐2 markedly reduced intracellular reactive oxygen species (ROS) generation, gamma‐glutamyltranspeptidase (GGT) activity, and tumor necrosis factor‐α (TNF‐α) levels and remarkably enhanced superoxide dismutase (SOD) and glutathione (GSH) activities. SHP‐1 and SHP‐2 also down‐regulated the expressions of GGT, bax, c‐caspase‐8/‐9/‐3, p‐Akt, p‐IκB‐α, p‐p65, p‐ERK, and p‐p38 but up‐regulated SOD, GSH, NF‐E2‐related factor 2 (Nrf2), heme oxygenase‐1 (HO‐1), and bcl‐2 levels, as revealed by Western blot analysis. Moreover, SHP‐1 and SHP‐2 increased the mitochondrial membrane potential (MMP), reduced DNA damage, and suppressed the nuclear translocation of p65. These results suggest that two peptides from seahorse hydrolysates can be considered a potential functional biomaterial and further improve the use value of seahorse in aquaculture.
