Outline of Final Research Achievements |
Osteosarcoma is a primary bone malignancies that predominates in children. No new therapeutic drug has been born for about 40 years, and the current treatment method administers a large amount of multiple anticancer drugs, resulting in serious side effects. This time, we examined the sensitizing effect of using decursin in combination with existing drugs, and examined whether side effects could be reduced. Decursin acted on the cell cycle to suppress cell proliferation and induce apoptosis in a concentration and time-dependent manner. In experiments using mice, decursin suppressed the increase in tumor volume, and when used in combination with cisplatin, it showed a further antitumor effect. Cisplatin-induced renal dysfunction and renal epithelial cell damage were ameliorated by the combined use of decursin.
