Dine on DNA: Compounds from nucleic acids in food show anticancer effects

(Press-News.org) When people eat, they ingest the nucleic acids that reside in all living things. The compounds in these acids could inhibit the growth of cancer cells, according to findings published in PLOS ONE by Osaka Metropolitan University Associate Professor Akiko Kojima-Yuasa of the Graduate School of Human Life and Ecology and colleagues.

Consuming nucleic acids found in food has been shown to boost the immune system and prevent some diseases. The nucleotides and nucleosides that result from digesting the acids are largely responsible for these beneficial effects.

Professor Kojima-Yuasa’s team used compounds of nucleic acids derived from salmon milt DNA and torula yeast RNA and showed that chemical compounds like guanosine could prevent the proliferation of certain cancer cells in laboratory rats. The compounds stopped the cells from starting their replication phase.

“Our research provides a new perspective on the physiological functions of nucleic acids derived from food,” Professor Kojima-Yuasa explained. “We hold hope that this will be a crucial step toward cancer prevention.”
