A new way to kill cancer cells


Researchers have found a new way to kill cancer cells by using artificial DNA.

Drugs based on nucleic acids -- namely DNA and RNA, the vital information-carrying molecules -- can control the biological functions of cells, and are expected to transform the future of medicine.

Nucleic acid drug use for cancer treatment has been challenging because it is difficult to make the nucleic acids distinguish between cancer cells and other healthy cells.

However, for the first time, a research team from the University of Tokyo has developed a hairpin-shaped DNA strand that can activate a natural immune response to target and kill specific cancerous cells.
