Cancer cells display altered cellular lipid metabolism, including disruption in endogenous lipid synthesis, storage, and exogenous uptake for membrane biogenesis and functions. Altered lipid metabolism and, consequently, lipid composition impacts cellular function by affecting membrane structure and properties, such as fluidity, rigidity, membrane dynamics, and lateral organization. Herein, we provide an overview of lipid membranes and how their properties affect cellular functions. We also detail how the rewiring of lipid metabolism impacts the lipidomic landscape of cancer cell membranes and influences the characteristics of cancer cells. Furthermore, we discuss how the altered cancer lipidome provides cues for developing lipid-inspired innovative therapeutic and diagnostic strategies while improving our limited understanding of the role of lipids in cancer initiation and progression. We also present the arcade of membrane characterization techniques to cement their relevance in cancer diagnosis and monitoring of treatment response.
癌细胞表现出改变的细胞脂质代谢,包括内源性脂质合成、储存和外源性摄取的破坏,以进行膜生物发生和功能。改变的脂质代谢和随之而来的脂质组成通过影响膜结构和特性(如流动性、刚性、膜动力学和横向组织)来影响细胞功能。本文概述了脂质膜及其特性如何影响细胞功能。我们还详细介绍了脂质代谢的重新布线如何影响癌细胞膜的脂质组学景观,并影响癌细胞的特征。此外,我们讨论了改变的癌症脂质组如何为开发基于脂质的创新治疗和诊断策略提供线索,同时提高我们对脂质在癌症发生和进展中的作用的有限理解。我们还介绍了一系列膜特性分析技术,以确定它们在癌症诊断和治疗反应监测中的相关性。
