Abstract
The infusion of Q. eduardii leaves has been used ancestrally for medicinal purposes. We investigated the effect of Q. eduardii infusion intake on inflammatory and oncogenic biomarkers in animals induced to have colorectal cancer with DMH. We also investigated its influence on the microbiota, establishing the main microbial metabolites in the intestinal content of the experimental animals. The microbial metabolites associated with greater anti-inflammatory and anticarcinogenic activity were 3́-hydroxyphenylacetic acid (3HPA) and €-3-(3,4,5-trimethoxyphenyl) prop-2-enoic acid (TMCA). Finally, the intake of the Q. eduardii infusion significantly increased the abundance of the Erysipelotrichaceae and Lachnospiraceae families, that seems to have a great influence on the antitumor responses detected in the study.
