ABSTRACT
Chlorogenic acid improves diabetic symptoms, including inflammation, via the modulation of the gut microbiota. However, the mechanism by which the microbiota is regulated by chlorogenic acid remains unknown. In this study, we firstly explored the effects of chlorogenic acid on diabetic symptoms, colonic inflammation, microbiota composition, and microRNA (miRNA) expression in db/db mice. The results showed that chlorogenic acid decreased body weight, improved glucose tolerance and intestinal inflammation, altered gut microbiota composition, and upregulated the expression level of five miRNAs, including miRNA-668-3p, miRNA-467d-5p, miRNA-129-1-3p, miRNA-770-3p, and miRNA-666-5p in the colonic content. Interestingly, the levels of these five miRNAs were positively correlated with the abundance of Lactobacillus johnsonii. We then found that miRNA-129-1-3p and miRNA-666-5p promoted the growth of L. johnsonii. Importantly, miRNA-129-1-3p mimicked the effects of chlorogenic acid on diabetic symptoms and colonic inflammation in db/db mice. Furthermore, L. johnsonii exerted beneficial effects on db/db mice similar to those of chlorogenic acid. In conclusion, chlorogenic acid regulated the gut microbiota composition via affecting miRNA expression and ameliorated intestinal inflammation via the miRNA-microbe axis in db/db mice.
