應用
经 PEG-过氧化氢酶处理的肺动脉内皮细胞可有效抑制 20-HETE(羟基二十碳四烯酸)诱导的荧光增强。但实验排除了 DCF(二氯荧光素)潜在的非特异性荧光。本实验研究了 20-HETE 对超氧化物产生和 NADPH 氧化酶活化的影响。
生化/生理作用
来自牛肝的过氧化氢酶催化 H 2 O 2 分解为水和氧。是一种四聚体,由分子量为 60 kDa 的四个相等的亚单位组成。每个亚基均含有与血红素 IX 基团结合的铁。该酶还能与靠近血红素基团的 NADP 强烈结合。过氧化氢酶活性在 pH 4.0-8.5 范围内恒定。pI 为 5.4。3-氨基-1-H-1,2,4 三唑、氰化物、叠氮化物、羟胺、溴化氰、2-巯基乙醇、二硫苏糖醇、联茴香胺和硝酸盐可抑制酶活性。用抗坏血酸或抗坏血酸/Cu 2 + 孵育过氧化氢酶会导致过氧化氢酶分子的降解。它不需要任何激活剂。

ERK-dependent signaling is key to many pathways through which extracellular signals are transduced into cell-fate decisions. One conundrum is the way in which disparate signals induce specific responses through a common, ERK-dependent kinase cascade. While studies have revealed intricate ways

The main characteristic of senescence is its stability which relies on the persistence of DNA damage. We show that unlike fibroblasts, senescent epithelial cells do not activate an ATM-or ATR-dependent DNA damage response (DDR), but accumulate oxidative-stress-induced DNA single-strand breaks

Seminolipid (also known as sulfogalactosylglycerolipid-SGG), present selectively in male germ cells, plays important roles in spermatogenesis and sperm-egg interaction. The proper degradation of SGG in apoptotic germ cells is also as important. Sertoli cells first phagocytose apoptotic germ cells, then

Myogenic contractions protect kidneys from barotrauma but are impaired in chronic kidney disease (CKD). Since myogenic contractions are enhanced by superoxide but impaired by hydrogen peroxide, we tested the hypothesis that they are counterregulated by superoxide and H2O2 from NOX2/p47phox and/or

Covalent conjugation of superoxide dismutase and catalase with polyethylene glycol (PEG) increases the circulatory half-lives of these enzymes from less than 10 min to 40 h, reduces immunogenicity, and decreases sensitivity to proteolysis. Because PEG has surface active properties and
