In some aspects, the disclosure provides methods of modulating the level of proteasome inhibitor resistance of a cell, the methods comprising manipulating the level of expression or activity of a subunit of the 19S proteasome in the cell. In some aspects, cells in which the level of a 19S subunit is modulated, e.g., reduced, are provided. In some aspects, methods of identifying agents that reduce proteasome inhibitor resistance are provided. In some aspects, methods of classifying cancers according to predicted proteasome inhibitor resistance are provided. In some aspects, methods of killing or inhibiting proliferation of cancer cells, e.g., proteasome inhibitor resistant cancer cells, are provided. In some aspects, methods of treating cancer, e.g., proteasome inhibitor resistant cancer, are provided.
在某些方面,本公开提供了调节细胞蛋白酶体抑制剂抗性水平的方法,这些方法包括操纵细胞中 19S 蛋白酶体亚基的表达水平或活性。在某些方面,提供了 19S 亚基水平被调节(如降低)的细胞。在某些方面,提供了鉴定降低蛋白酶体抑制剂耐药性的制剂的方法。在某些方面,提供了根据预测的蛋白酶体抑制剂耐药性对癌症进行分类的方法。在某些方面,提供了杀死或抑制癌细胞(如蛋白酶体抑制剂抗性癌细胞)增殖的方法。在某些方面,提供了治疗癌症(例如蛋白酶体抑制剂抗性癌症)的方法。
