瓦尔堡效应的起源和作用多年来一直不确定。最近的两项研究表明,丙酮酸激酶M2(PKM2)的胚胎和癌细胞特异性亚型通过与磷酸酪氨酸基序结合来调节,并促进细胞生长和肿瘤发展。PKM2增强糖酵解中间体用于大分子生物合成和肿瘤生长的使用。这些发现说明了这种代谢表型在癌细胞生长中的独特优势。
The origins and role of the Warburg effect have remained uncertain for many years. Two recent studies demonstrate that an embryonic- and cancer-cell-specific isoform of the enzyme pyruvate kinase M2 (PKM2) is regulated by binding to phospho-tyrosine motifs and promotes increased cell growth and tumor development. PKM2 enhances the use of glycolytic intermediates for macromolecular biosynthesis and tumor growth. These findings illustrate the distinct advantages of this metabolic phenotype in cancer cell growth.
