Flavonoid found in citrus slows lung cancer cell growth in lab tests

AI Summary

Laboratory experiments found that quercetin, a flavonoid present in citrus and other foods, slowed lung cancer cell division and nearly halted cell migration. Researchers at Universitätsklinikum Erlangen and Friedrich-Alexander Universität Erlangen-Nürnberg reported the findings in Cell Death Discovery.

Quercetin is found in citrus fruits, onions and buckwheat and is known for its anti-inflammatory properties. Now researchers at Universitätsklinikum Erlangen at Friedrich-Alexander Universität Erlangen-Nürnberg (FAU) have investigated how the plant compound could help treat lung cancer. In the lab, experiments showed that quercetin slows the division of lung cancer cells and almost completely stops their migration. The results have appeared in the journal Cell Death Discovery.
