An object to be solved by the present invention is to identify patients resistant to known HSP90 inhibitors, and to provide a novel therapeutic agent for treating the patients who have become resistant to known HSP90 inhibitors.
As a means for solving the above problems, the present invention provides identification of the patients based on a protein, which is an HSP90 family protein having a mutation in the site corresponding to F138 of HSP90α class A consisting of the amino acid sequence of SEQ ID NO: 1, and use of a substance that inhibits the protein as an active ingredient of a therapeutic agent.
本发明要解决的一个目的是鉴定对已知HSP90
抑制剂耐药的患者,并提供一种新型治疗剂用于治疗对已知HSP90
抑制剂耐药的患者。
作为解决上述问题的一种方法,本发明提供了基于一种蛋白质识别患者的方法,该蛋白质是一种在由
SEQ ID NO: 1的
氨基酸序列组成的HSP90α类A的F138对应位点发生突变的HSP90家族蛋白质,以及使用抑制该蛋白质的物质作为治疗剂的有效成分。
