The compound in the Mediterranean diet that makes cancer cells 'mortal'
Date:5/20/2013

COLUMBUS, Ohio New research suggests that a compound abundant in the Mediterranean diet takes away cancer cells' "superpower" to escape death.

By altering a very specific step in gene regulation, this compound essentially re-educates cancer cells into normal cells that die as scheduled.

One way that cancer cells thrive is by inhibiting a process that would cause them to die on a regular cycle that is subject to strict programming. This study in cells, led by Ohio State University researchers, found that a compound in certain plant-based foods, called apigenin, could stop breast cancer cells from inhibiting their own death.

Much of what is known about the health benefits of nutrients is based on epidemiological studies that show strong positive relationships between eating specific foods and better health outcomes, especially reduced heart disease. But how the actual molecules within these healthful foods work in the body is still a mystery in many cases, and particularly with foods linked to lower risk for cancer.

Parsley, celery and chamomile tea are the most common sources of apigenin, but it is found in many fruits and vegetables.

The researchers also showed in this work that apigenin binds with an estimated 160 proteins in the human body, suggesting that other nutrients linked to health benefits called "nutraceuticals" might have similar far-reaching effects. In contrast, most pharmaceutical drugs target a single molecule.

"We know we need to eat healthfully, but in most cases we don't know the actual mechanistic reasons for why we need to do that," said Andrea Doseff, associate professor of internal medicine and molecular genetics at Ohio State and a co-lead author of the study. "We see here that the beneficial effect on health is attributed to this dietary nutrient affecting many proteins. In its relationship with a set of specific proteins, apigenin re-establishes the normal profile in cancer c
