【摘要】 糖代谢与肿瘤的发生、发展、侵袭及转移密切相关,是恶性肿瘤的重要特征。HIF-1α是肿瘤细胞糖代谢表型转变的关键性因子,许多关键通路都通过HIF-1α与糖酵解相关联。针对HIF-1α-糖酵解通路及其调控因子的靶向治疗将成为肿瘤治疗新的方向。本文对近年来以HIF-1α及其上游调控因子为主要核心的恶性肿瘤糖代谢的分子机制及靶向治疗的研究进展进行综述。

Mechanism and Research Progress of HIF-1α Regulating Glucose Metabolism in Malignant Tumors/LIU Fule, WANG Gang. //Medical Innovation of China, 2021, 18(27): -176
[Abstract] Glucose metabolism is closely related to the occurrence, development, invasion and metastasis of tumors, and is an important feature of malignant tumors. HIF-1α is a key factor in the phenotypic transition of carbohydrate metabolism in tumor cells, and many key pathways are related to glycolysis through HIF-1α. Targeted therapy for HIF-1α-glycolysis pathway and its regulatory factors will become a new direction for tumor therapy. This article summarized the research progress of the molecular mechanism and targeted therapy of carbohydrate metabolism in malignant tumors with HIF-1α and its upstream regulatory factors in recent years.

糖代謝与肿瘤的发生、发展密切相关,近年在原有的靶向治疗的基础上,单独或辅以纠正糖代谢相关因子的治疗方法的研究取得了进展,但迄今为止,针对糖代谢的肿瘤治疗方案仍关注较少,以细胞代谢为标靶的药物研究成为新的研究目标[1-2]。肿瘤细胞普遍存在糖酵解的异常激活同线粒体的呼吸抑制,用以满足其恶性增殖的需要。这种糖代谢的改变和肿瘤细胞线粒体功能受损,微环境缺氧状态,均与糖酵解途径上游调控因子的异常激活密不可分。针对糖酵解通路及其上游调控因子,肿瘤细胞缺氧微环境的标靶治疗将会为肿瘤治疗提供新的方法策略[3]。
实体肿瘤普遍生长的微环境--低氧,低氧反应主要是通过关键因子-低氧诱导因子(hypoxia-inducible factors,HIFs)来介导的。HIFs(尤其HIF-1)对哺乳动物细胞适应低氧环境起到十分重要的作用,同时它对肿瘤细胞适应低氧的微环境也至关重要。HIF-1α是肿瘤细胞糖代谢表型转变的关键性因子,c-MYC等转录因子、PI3K-Akt-mTOR等通路均通过HIF-1α与糖酵解相关联。……
