KILL....A spicy way has been found to kill cancer cells.
SCIENTISTS have discovered that a substance found in turmeric, a basic curry ingredient, can kill cancer cells within 24 hours.
Researchers at Ireland's Cork Cancer Research Centre who treated
oesophageal cancer cells with curcumin, a chemical found in turmeric,
observed that it triggers lethal death signals in the cells. The cells eventually digest themselves and die. The results of the study were published in the British Journal of Cancer on Wednesday.
Curcumin gives turmeric (curcuma zangais) its orangy-yellow colour. The
rhizome, a close relative of the ginger, is commonly used in Asian
cooking as well as in traditional medicine.
Chinese and Ayurvedic medical practioners use turmeric as a treatment for many
ailments as it has anti-inflammatory, anti-fungal properties and
believed to lower cholestrol.
The results of the Cork Cancer Research Centre study were published in the British Journal of Cancer on Wednesday.
"These exciting results suggest that scientists can develop curcumin as a
potential anti-cancer drug to treat oesophageal cancer," said Dr Sharon
McKenna who led the study.

She said scientists had known hat natural compounds had the potential to
treat faulty cells that become cancerous, adding they also suspected
curcumin's possible therapeutic value.
She
said medical researcher Dr Geraldine O’Sullivan-Coyne who had been
looking for new ways of killing resistant oesophageal cancer cells
tested curcumin on resistant cells.
She found that they started to die using an unexpected system of cell messages.
Normally,
faulty cells die by committing programmed suicide or apoptosis which
occurs when proteins called caspases are ‘switched on’ in cells. But
these cells showed no evidence of suicide and the addition of a
molecule that inhibits caspases and stops this ‘switch being flicked’,
made no difference to the number of cells which died.
"This suggested that curcumin attacked cancer cells using an alternative cell signalling system," she added.
Oesophagus cancer kill more than half a million people in the world each year.
The cancers are exceptionally deadly, with five-year survival rates of
between 12 and 31 per cent.
The number of oesophageal cancer cases have gone up tremendously since the
70s and this is thought to be linked to rising rates of obesity,
alcohol intake and reflux disease. (Cancer Research UK)
