转移是肝细胞癌患者死亡的主要原因之一,而肝细胞癌向转移状态的发展依赖于局部微环境。低氧是影响肝细胞癌微环境的关键条件。目前,各种研究表明,缺氧诱导因子-1α(HIF-1α)的表达与肝癌的侵袭转移密切相关。HIF-1α高表达常导致肝细胞癌患者预后不良。本文综述了低氧诱导因子-1α的分子结构,并对低氧条件下肝细胞癌中低氧诱导因子-1α的表达模式进行了解释,该表达模式与肝细胞癌转移和预后不良有关。进一步探讨了HIF-1α功能与肝细胞癌转移的分子机制。低氧诱导因子-1α的调节可减少索拉非尼的耐药性,改善患者的预后。因此,HIF-1α可能是未来抑制肝细胞癌转移的重要靶点。
Metastasis is one of the major reasons for patient mortality in hepatocellular carcinoma (HCC), and the progression of HCC to a metastatic state depends on the local microenvironment. Hypoxia is a key condition affecting the microenvironment of HCC. Currently, various studies have shown that the expression of hypoxia-ainducible factor-1α (HIF-1α) is associated with the invasion and metastasis of HCC. High expression of HIF-1α often leads to poor prognosis in patients with HCC. In this review, the molecular structure of HIF-1α is described, and the expression pattern of HIF-1α in HCC under hypoxia, which is associated with metastasis and poor prognosis in HCC, is explained. The molecular mechanisms of HIF-1α function and the metastasis of HCC are further discussed. The modulation of HIF-1α can reduce sorafenib resistance and improve the prognosis of patients after TACE. Therefore, HIF-1α may be a critical target for inhibiting HCC metastasis in the future.
