Celery, artichokes contain flavonoids that kill human pancreatic cancer cells
Date:8/15/2013

estructs because its DNA has been damaged.

In one of the cancer cell lines, the percentage of cells undergoing apoptosis went from 8.4 percent in cells that had not been treated with the flavonoid to 43.8 percent in cells that had been treated with a 50-micromolar dose. In this case, no chemotherapy drug had been added.

Treatment with the flavonoid also modified gene expression. "Certain genes associated with pro-inflammatory cytokines were highly upregulated," de Mejia said.

According to Johnson, the scientists' in vitro study in Molecular Nutrition and Food Research is the first to show that apigenin treatment can lead to an increase in interleukin 17s in pancreatic cells, showing its potential relevance in anti-pancreatic cancer activity.

Pancreatic cancer patients would probably not be able to eat enough flavonoid-rich foods to raise blood plasma levels of the flavonoid to an effective level. But scientists could design drugs that would achieve those concentrations, de Mejia said.

And prevention of this frightening disease is another story. "If you eat a lot of fruits and vegetables throughout your life, you'll have chronic exposure to these bioactive flavonoids, which would certainly help to reduce the risk of cancer," she noted.
