A mechanism of monoamine oxidases (MAOs) driven epithelium-to-mesenchymal transition (EMT) is disclosed. Also disclosed are methods for treating cancer by inhibiting or suppressing MAOs in cancer cells. Novel MAOs inhibitors, such as small molecules, siRNA, shRNA, antisense oligonucleotides, aptamers, decoys, and pharmaceutical compositions useful for treating cancer by disrupting the workings of MAOs are provided. In particular, a class of conjugates formed by covalently conjugating near infrared dye 783, IR-780, and MHI-148 to a MAO inhibitor, such as clorgyline, with and without encapsulation it in a nanoparticle is provided. Other aspects of the invention include methods for forming the nano-conjugates, method for monitoring treatment progress in a cancer patient by monitoring the changes in MAO activity, methods for screening patients who are at risk of cancer or differentiating different forms of cancer by assaying the level and location of MAO activity.
本发明揭示了一种单胺氧化酶(MAOs)驱动的上皮-间质转化(EMT)机制。同时,本发明还揭示了通过抑制或抑制癌细胞中的MAOs来治疗癌症的方法。本发明提供了新型的MAOs抑制剂,例如小分子、siRNA、shRNA、反义寡核苷酸、aptamer、诱饵和制药组合物,用于通过破坏MAOs的作用来治疗癌症。特别地,本发明提供了一类共价结合近红外染料783、IR-780和MHI-148与MAO抑制剂(例如克洛吉林)形成的共轭物,有或没有包封在纳米粒子中。本发明的其他方面包括形成纳米共轭物的方法,通过监测MAO活性的变化来监测癌症患者的治疗进展的方法,通过测定MAO活性水平和位置来筛选癌症风险患者或区分不同类型的癌症的方法。
