代谢的重编程是癌细胞的基本特征之一,其中葡萄糖代谢方式和途径的改变对癌症的发生和发展至关重要。即使在氧气足够充足的情况下,快速增殖的癌细胞生长所需的能量主要由糖酵解而非氧化磷酸化提供,癌细胞这种特殊的糖代谢现象被称为Warburg效应。这种特有的能量获取方式已在多种癌细胞中得到验证,以癌细胞对葡萄糖高摄取率和利用增加为原理的18F-FDG PET/CT显像已广泛应用于临床的癌症诊断。但癌细胞为何利用有氧酵解获取能量以及有氧酵解进行的分子基础目前尚不明确,本文围绕调控癌细胞糖酵解进程中的直接调控酶、癌基因及致癌代谢小分子进行分析和综述。
Cancer metabolic reprogramming is among the basic characteristics of cancer cells. Changes in glucose metabolism are essential for carcinogenesis and cancer development. Previous study indicated that energy is acquired mainly via glycolysis rather than oxidative phosphorylation in the presence of sufficient oxygen levels to promote the rapid proliferation of cells, such as cancer cells. This phenomenon is called the"Warburg effect."Furthermore, this unique approach of energy production in cancer cells has been validated in various types of cancer cells. On the basis of the characteristics of cancer cells with high glucose uptake and utilization, cli-nicians and medical practitioners extensively apply 18-fludeoxyglucose positron emission tomography in clinical diagnosis. Tumor cells undergo aerobic glycolysis to produce energy, but this metabolic pathway is poorly efficient;the molecular basis of aerobic glycol-ysis and the reason for these cells to undergo this metabolic pathway also remain unclear. In this article, glycolysis-related processes, in-cluding enzyme, oncogene, and oncometabolite regulation, in cancer cells are summarized.
