Tobacco plant has key to fighting cancer

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.
‘The next step is to undertake pre-clinical studies to determine what role NaD1 might be able to play in treating cancer. The preclinical work is being conducted by the Melbourne biotechnology company Hexima. So far the preliminary trials have looked promising.
‘We are confident there is potential for this discovery to translate to therapeutic use in humans.
‘One of the biggest issues with current cancer therapies is that the effect of the treatment is indiscriminate,’ Dr Hulett said. ‘In contrast, we’ve found NaD1 can target cancerous cells and has little or no effect on those that are healthy.’
