(DMT1) have been identified that selectively target CSC by blocking lysosomal iron translocation. This leads to lysosomal iron accumulation, production of reactive oxygen species and cell death with features of ferroptosis. DMT1 inhibitors selectively target CSC in primary cancer cells and circulating tumor cells, demonstrating the physiological relevance of this strategy. Taken together, this opens up opportunities
癌症干细胞(CSC)构成实体肿瘤中的细胞亚群,负责对常规化学疗法,转移和癌症复发的抵抗力。天然产物沙利霉素可通过与溶酶体铁直接相互作用,利用CSC中铁稳态的上调来选择性地靶向该细胞生态位。在这里,已经确定了二价金属转运蛋白1(DMT1)的抑制剂可通过阻断溶酶体铁转运来选择性靶向CSC。这导致溶酶体铁的积累,活性氧的产生以及具有肥大病特征的细胞死亡。DMT1抑制剂在原发性癌细胞和循环肿瘤细胞中选择性靶向CSC,证明了该策略的生理相关性。综上所述,这为解决未满足的抗癌治疗需求提供了机会。
