in the laboratory, reveals research.

Scientists based at the Cork Cancer Research Centre in Ireland treated

oesophageal cancer cells with curcumin - a chemical found in the curry spice

tumeric.

 

They found that curcumin started to kill cancer cells within 24 hours. The cells

also began to digest themselves, according to the research, published in the

British Journal of Cancer.

 

Dr Sharon McKenna, lead study author, based at the Cork Cancer Research Centre,

University College Cork, said: " These exciting results suggests scientists could

develop curcumin as a potential anti-cancer drug to treat oesophageal cancer.

 

" Scientists have known for a long time that natural compounds have the potential

to treat faulty cells that have become cancerous and we suspected that curcumin

might have therapeutic value.

 

" Dr Geraldine O'Sullivan-Coyne, a medical researcher in our lab, had been

looking for new ways of killing resistant oesophageal cancer cells.

 

" She tested curcurmin on resistant cells and 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 the cancer cells using an alternative cell

signalling system.

Each year around 7,800 people are diagnosed with oesophageal cancer in the UK.

 

Less than 20 per cent of people survive oesophageal cancer beyond five years.

 

It is the sixth most common cause of cancer death and accounts for around five

per cent of all UK cancer deaths.

 

Dr Lesley Walker, director of cancer information at Cancer Research UK, said:

" This is interesting research which opens up the possibility that natural

chemicals found in tumeric could be developed into new treatments for

oesophageal cancer.

 

" Rates of oesophageal cancer rates have gone up by more than a half since the

70s and this is thought to be linked to rising rates of obesity, alcohol intake

and reflux disease so finding ways to prevent this disease is important too. "
