    摘要:

    器官移植是机体器官功能衰竭的主要治疗方法,而供体器官在离体运输过程中的功能保护是决定器官移植成功与否的关键,如何保护离体运输过程中的供体器官功能是当今器官移植研究领域的热点问题之一。在低氧环境下,组织细胞会激活一系列基因的转录活性,这些基因参与血管生成、铁代谢、葡萄糖代谢和细胞增殖/生存。在需氧生物体内,缺氧诱导因子-1α(hypoxia-inducible factors-1α,HIF-1α)参与多种基因表达的调控,以维持组织、细胞在缺氧条件下的内环境稳态,从而适应缺氧状态。多项研究表明HIF-1α信号通路在离体器官冷保存过程中,对其遭受的冷缺血损伤具有重要保护作用,是当前离体器官冷缺血损伤保护机制的研究热点,干预HIF-1α相关信号通路有望成为离体器官冷保存过程中维护器官功能的新策略。

    Abstract:

    Organ transplantation is the main treatment for organ failure. The functional protection of donor organs during ex vivo transportation is the key to the success of organ transplantation. How to protect the functions of donor organs during in vitro transportation is one of the key issues in the field of organ transplantation research. In a hypoxic environment, the transcriptional activity of a series of genes in cells is activated. These genes are mainly involved in angiogenesis, iron metabolism, glucose metabolism, and cell proliferation/survival. In aerobic organisms, hypoxia-inducible factor-1α (HIF-1α) is involved in the regulation of the expression of various genes to maintain the homeostasis of tissues and cells under hypoxic conditions, thereby adapting to the hypoxia. Many studies have shown that the HIF-1α pathway plays an important role in protecting isolated organs from cold ischemia injury during cold storage. HIF-1α has been a hot spot in the research on the protective mechanism of cold ischemia injury of isolated organs. The intervention of the HIF-1α-related signal pathway is expected to become a new strategy for maintaining organ function during cold storage of isolated organs.
