Japanese Fruit Sarunashi Shows Potential in Preventing Lung Cancer in Mice
Researchers at Okayama University have identified a small Japanese fruit, Sarunashi (Actinidia arguta), also known as the kiwiberry, as a potential agent in preventing lung cancer. In a study published in the journal Genes and Environment, the fruit's juice was found to reduce lung tumor formation in mice exposed to NNK, a carcinogen related to tobacco. The juice also decreased the number of tumor nodules in the lungs, and its compound isoquercetin demonstrated protective effects. The study suggests that Sarunashi juice may interfere with the initiation and growth of cancer by reducing DNA damage and supporting DNA repair mechanisms. While these findings are promising, clinical trials are necessary to confirm the fruit's efficacy in humans.
