| 摘要: |
| 氧稳态对细胞功能的维持至关重要，缺氧诱导因子（HIF）氧感知信号通路在氧浓度调节及氧稳态维持中发挥了十分重要的作用。高氧至常氧、常氧至低氧的变换会使细胞处于相对缺氧状态，可触发通常由缺氧引发的细胞内级联反应，增强细胞对抗缺氧的能力，这种现象被称为“高氧-低氧悖论”（HHP），其机制与HHP诱导HIF-1α表达上调有关。本文就HIF氧感知信号通路与HHP的研究进展进行综述。 |

| Abstract: |
| Oxygen homeostasis is crucial for the maintenance of cell function. Hypoxia-inducible factor (HIF) oxygen-sensing pathway plays an important role in the regulation of oxygen concentration and the maintenance of oxygen homeostasis. The change from hyperoxia to normoxia or from normoxia to hypoxia can put cells in a relatively hypoxic state, and it can trigger the intracellular cascade reaction usually triggered by hypoxia and enhance the ability of cells to resist hypoxia. This phenomenon is called "hyperoxic-hypoxic paradox" (HHP), and its mechanism is related to the up-regulation of HIF-1α induced by HHP. This paper reviews the research progress of HIF oxygen-sensing pathway and HHP. |
