  • 最新研究進展：
    GPX1是一種谷胱甘肽過氧化物酶，可以清除細胞內(nèi)的過氧化氫等活性氧，具有抗氧化和細胞保護作用。最新研究表明，GPX1在多種疾病的發(fā)生和發(fā)展中發(fā)揮重要作用。例如，一些研究發(fā)現(xiàn)GPX1與心血管疾病、癌癥和糖尿病等疾病的風險存在相關(guān)性。此外，一些研究還發(fā)現(xiàn)GPX1在免疫調(diào)節(jié)、神經(jīng)保護和干細胞分化等方面發(fā)揮著重要作用。

    1. Knockdown of nNOS or GPx1 was specific and had broad effects on downstream genes, though it only modestly ameliorated traumatic brain injury-induced working memory deficits, despite widespread genomic changes. PMID: 29016640
    2. The glutathione peroxidase activity and p110-PI3K/Thr308-Akt are both modulated in the same way by oxygen. PMID: 24401635

    6. It represents the pivotal antioxidant enzyme in vascular endothelium and exerts a protective effect against the presence of coronary artery disease PMID: 24389817
    7. data collectively indicate that GDNF is capable of inducing anti-oxidant activities of intra-cellular GPX-1 and that growth-promoting potential of GDNF and anti-oxidant properties of GPX-1 can, in concert, maximize survival of dopaminergic neurons. PMID: 23472740
    8. Upon selenium fluctuation, the modulation of UGA recoding efficiency depends on the nature of the SECIS, with Gpx1 being more sensitive than Gpx4. PMID: 22614831
    9. GPx levels in the cortex and hippocampus were increased in OLETF rats compared with LETO rats, with an inverse correlation between GPx in the hippocampus and learning score. PMID: 22981416
    10. The glutathione peroxidase represents an important part of the antioxidant defense system. PMID: 20524817
    11. expression of glutathione peroxidase 1 and glutathione reductase via GSH did not appear to coordinate with development, tissue localization or under oxidative stress PMID: 12516874
    12. excess amounts of PLOOH are efficiently eliminated through the hydrolysis by PLA2, and the subsequent reduction of FA hydroperoxide by GPx is the critical step for complete detoxification of oxidized phospholipids in the stomach PMID: 12934674
    13. Over-expression gpx1 genes in primary hippocampal or cortical cultures resulted in increased enzymatic activity of the cognate protein. PMID: 14713308
    14. Gxp1 levels was increased indicating that a reduction in oxidative damage protection may be responsible for accelerated telomere shortening over time, resulting in increased cellular senescence, loss of renal function, and death in male rats. PMID: 16189290
    15. Novel sites of Gpx1 expression were observed in colon lymphatic tissue. PMID: 16229841
    16. Our results suggest that impairment of the GPx (including glutathione)-mediated antioxidant system contributed to epileptogenesis in GEPR-9s. PMID: 18226427
