AI Article Synopsis
- Researchers studied quercetin's effects on salivary secretion to find a treatment for dry mouth.
- In a mouse model with radiation-induced reduced salivation, quercetin improved secretion levels, while normal mice also showed enhanced salivation with quercetin.
- The study indicated that quercetin works by increasing AQP5 expression and calcium uptake, while reducing oxidative stress and inflammation, highlighting its potential as a treatment for dry mouth.
Article Abstract
With the aim of discovering an effective method to treat dry mouth, we analyzed the effects of quercetin on salivary secretion and its mechanism of action. We created a mouse model with impaired salivary secretion by exposure to radiation and found that impaired secretion is suppressed by quercetin intake. Moreover, secretion levels were enhanced in quercetin-fed normal mice. To elucidate the mechanisms of these effects on salivary secretion, we conducted an analysis using mouse submandibular gland tissues, a human salivary gland epithelial cell line (HSY), and mouse aortic endothelial cells (MAECs). The results showed that quercetin augments aquaporin 5 (AQP5) expression and calcium uptake, and suppresses oxidative stress and inflammatory responses induced by radiation exposure, suggesting that quercetin intake may be an effective method to treat impaired salivary secretion.
