The compound in the Mediterranean diet that makes cancer cells 'mortal'

occur when only one would take place in a normal cell a trick on the cancer cells' part to keep them alive and reproducing.

In this study, the researchers observed that apigenin's connection to the hnRNPA2 protein restored this single-splice characteristic to breast cancer cells, suggesting that when splicing is normal, cells die in a programmed way, or become more sensitive to chemotherapeutic drugs.

"So by applying this nutrient, we can activate that killing machinery. The nutrient eliminated the splicing form that inhibited cell death," said Doseff, also an investigator in Ohio State's Davis Heart and Lung Research Institute. "Thus, this suggests that when we eat healthfully, we are actually promoting more normal splice forms inside the cells in our bodies."

The beneficial effects of nutraceuticals are not limited to cancer, as the investigators previously showed that apigenin has anti-inflammatory activities.

The scientists noted that with its multiple cellular targets, apigenin potentially offers a variety of additional benefits that may even occur over time. "The nutrient is targeting many players, and by doing that, you get an overall synergy of the effect," Grotewold explained.

Doseff is leading a study in mice, testing whether food modified to contain proper doses of this nutrient can change splicing forms in the animals' cells and produce an anti-cancer effect.
