开发酶诱导的功能获得策略以选择性地杀死具有高ALP活性的癌细胞。选择性杀死癌细胞和避免耐药性仍然是癌症治疗中的困难挑战。在这里,我们报告了一种新的策略,使用酶诱导的功能增益(EIGF)来调节磷酸化蜂毒肽类似物(MelAs)的结构和功能。原始MelA具有破坏质膜并诱导细胞死亡的能力,而没有选择性。然而,在MelA之一(MelA 2-P)上的Thr 23的磷酸化有效地改善了膜溶解效力以及对正常哺乳动物细胞的细胞毒性。在用碱性磷酸酶(ALP)(其在癌细胞中比正常细胞更活跃)处理后,MelA 2-P恢复了癌细胞周围的孔形成功能,并选择性地诱导癌细胞死亡。这种机制不依赖于受体蛋白和细胞摄取过程,这可能部分绕过癌细胞中耐药性的发展。
Developing an enzyme-induced gain of function strategy to selectively kill cancer cells with high ALP activity. The selective killing of cancer cells and the avoidance of drug resistance are still difficult challenges in cancer therapy. Here, we report a new strategy that uses enzyme-induced gain of function (EIGF) to regulate the structure and function of phosphorylated melittin analogues (MelAs). Original MelAs have the capacity to disrupt plasma membranes and induce cell death without selectivity. However, phosphorylation of Thr23 on one of the MelAs (MelA2-P) efficiently ameliorated the membrane lysis potency as well as the cytotoxicity for normal mammalian cells. After treatment with alkaline phosphatase (ALP), which is more active in cancer cells than normal cells, MelA2-P restored the pore-forming function around the cancer cells and induced cancer cell death selectively. This mechanism was independent of the receptor proteins and the cell uptake process, which may partially bypass the development of drug resistance in cancer cells.
