| Description | 4-Hydroxynonenal (4-HNE) (4-HNE) is an oxidative/nitrosative stress biomarker. It is a substrate and an inhibitor of acetaldehyde dehydrogenase 2 (ALDH2). |
| In vitro | 4-Hydroxynonenal 同时是ALDH2的底物和抑制剂;在低浓度下,对ALDH2的抑制是可逆的,而当4-HNE浓度达到10 μM时变为不可逆。4-Hydroxynonenal能诱导抗氧化防御机制,限制自身产生并增强细胞对抗氧化应激的保护。作为脂质过氧化的产物,4-Hydroxynonenal在病毒、细菌和哺乳动物细胞中具有突变原性和基因毒性。它与四种DNA碱基反应,但效率不同:G > C > A > T。4-Hydroxynonenal-dG是4-Hydroxynonenal基因毒性效应的最佳生物标志物,这些加合物主要存在于核DNA中[1]。 |
| In vivo | 在流体撞击损伤(FPI)24小时后,对小鼠大脑组织进行了NADPH氧化酶1(NOX1)、诱导性一氧化氮合酶(iNOS)、4-Hydroxynonenal (4-HNE)表达水平进行了分析。相较于未受伤的Nrf2+/+和Nrf2-/-小鼠,野生型(Nrf2+/+)和Nrf2缺陷型小鼠(Nrf2-/-)在15 psi损伤(中度损伤)后4-Hydroxynonenal 的表达水平均出现上升。与iNOS结果相似,在Nrf2-/-敲除(KO)小鼠中,与相应受伤和未受伤的Nrf2+/+野生型(WT)动物相比,4-Hydroxynonenal 的表达水平显著上升[2]。 |
