The role of lipid metabolism has gained particular interest in prostate cancer research. A large body of literature has outlined the unique upregulation of de novo lipid synthesis in prostate cancer. Concordant with this lipogenic phenotype is a metabolic shift, in which cancer cells use alternative enzymes and pathways to facilitate the production of fatty acids. These newly synthesized lipids may support a number of cellular processes to promote cancer cell proliferation and survival. Hence, de novo lipogenesis is under intense investigation as a therapeutic target. Epidemiologic studies suggest dietary fat may also contribute to prostate cancer; however, whether dietary lipids and de novo synthesized lipids are differentially metabolized remains unclear. Here, we highlight the lipogenic nature of prostate cancer, especially the promotion of de novo lipid synthesis, and the significance of various dietary lipids in prostate cancer development and progression.
脂质代谢在前列腺癌研究中备受关注。大量文献阐述了前列腺癌中从头合成脂质的独特上调。与这种生脂表型一致的是代谢转变,癌细胞利用替代酶和途径来促进脂肪酸的产生。这些新合成的脂质可能支持许多细胞过程,促进癌细胞增殖和存活。因此,从头合成脂质作为治疗靶点受到了广泛关注。流行病学研究表明,饮食中的脂肪也可能导致前列腺癌;然而,饮食中的脂质和从头合成的脂质是否以不同的方式代谢尚不清楚。在这里,我们强调了前列腺癌的生脂特性,特别是从头合成脂质的促进作用,以及各种膳食脂质在前列腺癌发生和发展中的意义。
