Platinum (IV) coiled coil nanotubes selectively kill human glioblastoma cells

Abstract

The prognosis of malignant glioma remains poor despite medical advances. Platinum, one of the chemotherapeutic agents used, has significant systemic side effects. In this article, the authors employed α-helical right handed coiled coil (RHCC) protein nanotubes as a carrier for cisplatin. It was shown that the new compound achieved higher tumor kill rate but lower toxicity to normal cells and thus may hold promise to be a highly efficient treatment for the future.
