Abstract

The mitochondrial electron transport chain (ETC) has been an attractive target for cancer therapy due to its essentiality for tumor growth. Krall et al. found that under ETC dysfunction, a decrease in asparagine limits cancer cell proliferation and activates the integrated stress response, creating a therapeutically exploitable metabolic vulnerability.

摘要

线粒体电子传递链(ETC)因其对肿瘤生长的重要性而成为癌症治疗的一个有吸引力的靶点。Krall 等人发现,在 ETC 功能障碍下,天冬酰胺的减少会限制癌细胞的增殖并激活整体应激反应,从而产生一种可治疗的代谢脆弱性。
