Abstract

Nrf2 is active protein presents in the cytoplasm in the cells of the body. In the presence of an activators, Nrf2 can enter the nucleus which bind to Antioxidant Responses Elements (ARE) or otherwise named human ARE (hARE) which control the whole antioxidants activity in human cell. Many factors may contribute to defective or overwhelmed cellular antioxidants activities for instances aging and cellular damages. These cellular damages can be produced by free radicals or oxidative stress. In the mechanism, if Nrf2 activated in the nucleus, can caused the production of collaborative antioxidants enzymes especially: catalase, glutathione (GLT) and superoxide dismutase (SOD) as a responsible for detoxification of free radical inside the cells.

Nrf2作为氧化应激的调节剂
Nrf2是存在于机体细胞细胞质中的活性蛋白。在激活因子存在的情况下,Nrf2可以进入细胞核,与抗氧化反应元件(anti - oxide Responses Elements, ARE)结合,或称为人类抗氧化反应元件(human ARE, hARE),后者控制人类细胞的整个抗氧化活性。许多因素可能导致细胞抗氧化剂活性缺陷或过度,例如衰老和细胞损伤。这些细胞损伤可由自由基或氧化应激产生。在机制上,如果Nrf2在细胞核中被激活,可以引起协同抗氧化剂酶的产生,特别是过氧化氢酶、谷胱甘肽(GLT)和超氧化物歧化酶(SOD),这些酶负责细胞内自由基的解毒。
