Recently, the team of Professor Zhang Yan and Professor Wang Shuo of Nankai University published an online article titled "Grape seed extract ameliorates PhIP-induced colonic injury by modulating gut microbiota, lipid metabolism, and NF-κB signaling pathway in rats" in the Journal of Functional Foods.
This study explored the protective effect and mechanism of grape seed extract (GSE) on colon injury caused by short-term exposure to PhIP.
Professor Zhang Yan and Professor Wang Shuo of Nankai University are the corresponding authors of this article.
Focus:
Grape seed extract (GSE) improves 2-Amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (2-Amino-1-methyl-6-phenylimidazo[4, 5-b]pyridine, PhIP) induced oxidative stress and DNA damage.
GSE improves the intestinal flora disorder caused by PhIP.
GSE improves lipid metabolism disorders caused by PhIP.
The NF-κB signaling pathway is involved in the process of colon protection.
Summary
2-Amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) is rich in protein A common carcinogen produced during thermal processing of foods.
Xiuli Zhao of the State Key Laboratory of Food Nutrition and Safety of Tianjin University of Science and Technology, Yan Zhang and Shuo Wang of Nankai University School of Medicine, and others discussed the protection of grape seed extract (GSE) on colon injury induced by short-term exposure to PhIP Function and its mechanism.
Wistar rats were randomly divided into control group, GSE only group (GSE), PhIP group (PhIP) and GSE prevention group (GPhIP).
In the GPhIP group, the rats were fed a diet supplemented with GSE for 2 weeks before PhIP was administered.
GSE can significantly improve PhIP-induced oxidative stress and colonic DNA damage.
In addition, GSE effectively maintains the homeostasis of the intestinal flora, especially to prevent PhIP-mediated reduction in the abundance of lactic acid bacteria.
Stool metabolome and colonic transcriptome analysis showed that GSE significantly improved PhIP-induced colon damage by regulating lipid metabolism.
It is worth noting that the NF-κB signaling pathway is involved in the process of prevention and protection.
Therefore, it is recommended to use GSE as an effective dietary supplement to prevent the harm of PhIP in the body.
