Cancer cells are often exposed to a metabolically challenging environment with scarce availability of oxygen and nutrients. This metabolic stress leads to changes in the balance between the endogenous synthesis and exogenous uptake of fatty acids, which are needed by cells for membrane biogenesis, energy production and protein modification. Alterations in lipid metabolism and, consequently, lipid composition have important therapeutic implications, as they affect the survival, membrane dynamics and therapy response of cancer cells. In this article, we provide an overview of recent insights into the regulation of lipid metabolism in cancer cells under metabolic stress and discuss how this metabolic adaptation helps cancer cells thrive in a harsh tumour microenvironment.

代谢应激下癌细胞中的脂质代谢。

癌细胞经常暴露于缺乏氧气和养分的代谢困难的环境中。这种代谢应激导致脂肪酸的内源性合成与外源性摄取之间的平衡发生变化,这是细胞进行膜生物发生,产生能量和修饰蛋白质所需要的。脂质代谢的改变以及因此脂质组成的改变具有重要的治疗意义,因为它们影响癌细胞的存活,膜动力学和治疗反应。在本文中,我们提供了对代谢压力下癌细胞脂质代谢调控的最新见解的概述,并讨论了这种代谢适应如何帮助癌细胞在恶劣的肿瘤微环境中壮成长。
