Tumour cells undergo oncogene-regulated metabolic reprogramming that maximizes survival and growth. However, little is known about metabolic interactions between tumour cells and their non-malignant neighbours in the stroma. Bone-marrow-derived stromal cells are now shown to provide cysteine, an essential nutrient that enables leukaemia cells to resist oxidative stress.
肿瘤细胞经历了癌基因调控的代谢重编程,以最大限度地提高生存和生长。然而,肿瘤细胞与其基质中非恶性相邻细胞之间的代谢相互作用知之甚少。现在已经表明,骨髓衍生的基质细胞提供半胱氨酸,这是一种必需的营养物质,使白血病细胞能够抵抗氧化应激。
