'''Grape extract kills cancer cells ''' | |||

An extract from grape seeds can destroy cancer cells, US research suggests. | |||
In lab experiments, scientists found that the extract stimulated leukaemia cells to commit suicide. | |||
Within 24 hours, 76% of leukaemia cells exposed to the extract were killed off, while healthy cells were unharmed, Clinical Cancer Research reports. | |||
The study raises the possibility of new cancer treatments, but scientists said it was too early to recommend that people eat grapes to ward off cancer. | |||
Grape seeds contain a number of antioxidants, including resveratrol, which is known to have anti-cancer properties, as well as positive effect on the heart. | |||
Previous research has shown grapeseed extract has an effect on skin, breast, bowel, lung, stomach and prostate cancer cells in the laboratory. | |||
It can also reduce the size of breast tumours in rats and skin tumours in mice. | |||
However, the University of Kentucky study is the first to test its impact on a blood cancer. | |||
Lead researcher Professor Xianglin Shi said: "These results could have implications for the incorporation of agents such as grapeseed extract into prevention or treatment of haematological (blood) malignancies and possibly other cancers. | |||
"What everyone seeks is an agent that has an effect on cancer cells but leaves normal cells alone, and this shows that grapeseed extract fits into this category." | |||
The researchers exposed leukaemia cells to grape extract in a range of different doses. | |||
:Apoptosis | |||
One of the higher doses produced a marked effect, causing large numbers of the cells to commit suicide in a process known as apoptosis. | |||
This is a natural method of getting rid of damaged and potentially dangerous cells. | |||
When the mechanism behind apoptosis breaks down, cancerous cells can survive and multiply. | |||
The researchers found grapeseed extract activates a protein called JNK which helps to regulate apoptosis. | |||
When they exposed the leukaemia cells to an agent that inhibits JNK, the grapeseed extract effect was cancelled out. | |||
Silencing the gene that makes JNK also blocked the extract's ability to kill cancer cells. | |||
Kat Arney, Cancer Research UK's senior cancer information officer, warned against jumping to firm conclusions. | |||
She said: "This is yet another story highlighting the potential cancer-fighting properties of naturally-occurring chemicals. | |||
"Although interesting, it's still a long way from being a treatment that we can give to patients." | |||
