己糖激酶Ⅱ与肿瘤增殖及靶向治疗

摘要/Abstract

摘要：肿瘤细胞所需能量主要来自有氧糖酵解途径，即Warburg效应，该生化过程同时为肿瘤细胞提供生长所需的大量前体物质。已糖激酶Ⅱ（HKⅡ）为糖酵解的限速酶，在肿瘤组织中高表达，与肿瘤的能量代谢密切相关。近年来研究表明肿瘤细胞中的HKⅡ不仅介导Warburg效应，还能抑制肿瘤细胞凋亡、调节自噬而发挥促进肿瘤增殖的作用。已在多种肿瘤细胞中证实，阻断HKⅡ基因表达及应用HKⅡ的小分子抑制剂均可起到杀伤肿瘤的作用，以HKⅡ为靶点的抑制剂有可能成为新一代靶向药物。

Abstract:The energy for tumor cells mainly derives from the aerobic glycolysis, that is, the Warburg effect, which also provides a large amount of precursor substances for the growth of tumor cells. HexokinaseⅡ (HKⅡ), highly expressed in tumor tissue, is the ratelimiting enzyme of glycolysis and closely related to the energy metabolism of tumor. Recent studies have showed that HKⅡ not only mediates Warburg effect, but also promotes tumor proliferation by inhibiting tumor cell apoptosis and regulating autophagy. It has been confirmed that blocking HKⅡ gene expression and inhibiting HKⅡ with small molecule inhibitor can kill tumor cells in many kinds of cancer. Agent targeting HKⅡ may become a new generation of targeted drugs.
