    • Disclosed herein is a method for inducing Hsp72 production in a cell. The method involves contacting the cell transiently with a proteasome inhibitor in an amount sufficient to induce Hsp72 production. Preferably Hsp72 levels are induced to a level sufficient for the suppression of stress-activated kinase activity attributable, for example, to a stress-activated kinase selected from the group consisting of JNK and p38. The method has both in vitro and in vivo applications. Also disclosed is a method of the type described above is applied specifically to aged cells. Also disclosed is a method for treating pathologies associated with apoptosis and inflammation in an individual. The method involves administering to the individual a proteasome inhibitor in an amount sufficient to induce Hsp72 production. In a preferred embodiment of the therapeutic method, the individual is an aged individual. Stress-induced pathologies such as ischemia are particularly important with respect to the therapeutic aspect of the invention. Also disclosed is a method for identifying an organic compound having the ability to induce Hsp72 levels in aged cells to a level sufficient to suppress stress-activated kinase activity.
    • 本文公开了一种在细胞中诱导Hsp72产生的方法。 该方法包括使细胞与蛋白酶体抑制剂瞬时接触,其量足以诱导Hsp72产生。 优选Hsp72水平被诱导到足以抑制应激激活的激酶活性的水平,其归因于例如选自JNK和p38的应激激活的激酶。 该方法具有体外和体内应用。 还公开了上述类型的方法专门应用于老化细胞。 还公开了一种用于治疗个体中凋亡和炎症相关病理的方法。 该方法包括以足以诱导Hsp72产生的量向个体施用蛋白酶体抑制剂。 在治疗方法的优选实施方案中,个体是老年个体。 对于本发明的治疗方面,应激诱导的病症如缺血是特别重要的。 还公开了一种用于鉴定具有将老化细胞中的Hsp72水平诱导到足以抑制应激激活的激酶活性的水平的能力的有机化合物的方法。
