肿瘤异常脂肪酸代谢研究进展*

肿瘤细胞具有不同于正常细胞的生物学性状和能量代谢机制。最初发现的肿瘤细胞特殊代谢表型称为Warburg效应，后来研究发现恶性肿瘤生长增殖所需的脂肪酸主要来源于从头合成途径，且脂肪酸合成和氧化代谢相关的重要酶类在肿瘤组织中过度表达而在正常组织中不表达或低表达。异常脂肪酸代谢与肿瘤生长、存活及侵袭相关，表明异常脂肪酸代谢为肿瘤生长提供了至关重要的物质和能量来源。近年来，肿瘤细胞异常脂肪酸代谢特异性表型逐渐引起人们高度重视，探索异常脂肪酸代谢在肿瘤生物学中的作用，以及通过靶向脂肪酸代谢途径治疗恶性肿瘤的策略正备受关注。本文就异常脂肪酸代谢对肿瘤形成、发展的意义及特异性抑制剂研发进展作一综述。

Research progress on abnormal fatty acid metabolism in cancer cells

Cancer cells frequently share biological characteristics and energy metabolic processes distinct from normal cells. The specific metabolic phenotype was originally known as the Warburg effect. Researchers later discovered that cancer cells prefer to synthesize fatty acid de novo . Moreover, key enzymes involved in fatty acid synthesis andβ - oxidation are overexpressed in tumor tissues, with low or without expression in normal tissues. Abnormal fatty acid metabolism is related to the survival and invasiveness of cancer cells, indicating that abnormal fatty acid metabolism provides the crucial components and energy sources of cancer cells. In recent years, the specific phenotype of abnormal fatty acid metabolism and the exploration of the role of this metabolic alteration in cancer biology and therapeutic strategies targeting the fatty acid metabolic pathways have become attractive focuses in cancer research. The role of active fatty acid metabolism in tumorigenesis and development, as well as the research progress in the development of the specific inhibitors, is reviewed in this paper.
