Nature:抗癌“神药”也救不了肿瘤耐药?原来癌细胞偷偷改了代谢方式,抑制脂肪酸代谢是突破口

癌细胞耐药怎么破?

在很多时候,癌细胞就像是“打不死的小强”,即使在实验室中展现出惊人疗效的治疗药物,也难以阻挡一部分癌细胞“死里逃生”的脚步,更可气的是,这些残存的癌细胞能够继续增殖,无视杀伤性药物并持续“壮大”队伍,导致疾病再次复发和耐药性问题的恶化,最终令患者面临死亡的威胁。 为了揭开部分癌细胞能够抵抗药物治疗的原因,哈佛医学院、麻省理工学院以及博德研究所的研究人员合作开发了一种独特的DNA追踪系统,对药物作用下癌细胞的变化进行了追踪,最终找到部分癌细胞“强悍”到无惧药物攻击的原因。 原来,在疾病治疗早期,一部分癌细胞便展现出“刀枪不入”的特质,其中少部分癌细胞甚至能够随着药物反应而改变自己的代谢方式,从而保持生长和繁殖的能力,如果阻断这些癌细胞独特的代谢途径,便能够抑制耐药细胞进一步扩张,增强癌症治疗效果。相关报告以Cycling cancer persister cells arise from lineages with distinct programs为题发表在8月11日的《Nature》期刊上。 https://doi.org/10.1038/s41586-021-03796-6 在这项
