实体瘤通常会形成以不规则血管化和缺氧(O2)和营养供应为特征的恶劣微环境。虽然正常细胞调节合成代谢和分解代谢途径以响应营养物质可用性的变化,但癌细胞即使在营养物质缺乏的情况下也表现出不受调节的生长。最近的研究表明,组成性激活的生长促进途径的结果依赖于不饱和脂肪酸的生存下O2剥夺。在癌细胞中,这种依赖性代表了一种关键的代谢脆弱性,可以用于治疗。在这里,我们回顾这种依赖不饱和脂质是如何受到癌细胞所面临的微环境条件的影响。
Solid tumors typically develop hostile microenvironments characterized by irregular vascularization and poor oxygen (O2) and nutrient supply. While normal cells modulate anabolic and catabolic pathways in response to changes in nutrient availability, cancer cells exhibit unregulated growth even under nutrient scarcity. Recent studies have demonstrated that constitutive activation of growth-promoting pathways results in a dependence on unsaturated fatty acids for survival under O2 deprivation. In cancer cells, this dependence represents a critical metabolic vulnerability that could be exploited therapeutically. Here we review how this dependence on unsaturated lipids is affected by the microenvironmental conditions faced by cancer cells.
