摘要
The heat shock protein mortalin is frequently overexpressed in human malignancies. In this study, an assessment of mortalin expression using ovarian cancer tissue microarrays suggested that mortalin overexpression might be related to drug resistance. Using a short hairpin (sh) RNA approach, we evaluated the effect of reducing mortalin expression in vitro and in vivo. The results of our study show that elevated levels of mortalin expression increase cancer cell resistance to cisplatin-induced cytotoxicity and identify mortalin as a potential therapeutic target for improved treatment of drug-resistant ovarian cancer.
