Research Abstract

We have reported that the klotho gene, which is an anti-aging gene known to be a tumor suppressor, is a prognostic factor for lung cancer patients (Usuda J et al. Lung Cancer. 2011). In this study, we determined whether klotho expression may have a predictive value of the efficacy of anti-cancer agents for cancer treatment. We performed transfection of klotho-plasmid into MCF-7c3 cells, which stably express procaspase-3, and treated the cells with various kinds of anti-cancer agents. A high expression of the klotho protein can markedly increase the apoptotic response of MCF-7c3 cells to docetaxel and paclitaxel. These results suggest that klotho expression may indicate the predictive value of chemotherapy and play an important role in cancer treatment.
