La Trobe University research has revealed a tobacco plant’s natural defence mechanisms could be harnessed to kill cancer cells in the human body.
Scientists at the La Trobe Institute for Molecular Science have identified that a molecule occurring in the flower of the plant that fights off fungi and bacteria also has the ability to identify and destroy cancer.
The defence molecule, called NaD1, works by forming a pincer-like structure that grips onto lipids present in the membrane of cancer cells and rips it open, causing the cell to expel its contents and explode.
The results are published in the journal eLife today.
Lead investigator Dr Mark Hulett said the discovery has potential for use in cancer treatment.
‘There is some irony in the fact that a powerful defence mechanism against cancer is found in the flower of a species of ornamental tobacco plant, but this is a welcome discovery, whatever the origin,’ Dr Hulett said.
