Abstract

Excess weight and obesity are severe public health threats worldwide. Recent evidence demonstrates that gut microbiota dysbiosis contributes to obesity and its comorbidities. The body weight‐reducing and energy balancing effects of melatonin have been reported in several studies, but to date, no investigations toward examining whether the beneficial effects of melatonin are associated with gut microbiota have been carried out. In this study, we show that melatonin reduces body weight, liver steatosis, and low‐grade inflammation as well as improving insulin resistance in high fat diet (HFD)‐fed mice. High‐throughput pyrosequencing of the 16S rRNA demonstrated that melatonin treatment significantly changed the composition of the gut microbiota in mice fed an HFD. The richness and diversity of gut microbiota were notably decreased by melatonin. HFD feeding altered 69 operational taxonomic units (OTU s) compare with a normal chow diet (NCD) group, and melatonin supplementation reversed 14 OTU s to the same configuration than those present in the NCD group, thereby impacting various functions, in particular through its ability to decrease the Firmicutes‐to‐Bacteroidetes ratio and increase the abundance of mucin‐degrading bacteria Akkermansia, which is associated with healthy mucosa. Taken together, our results suggest that melatonin may be used as a probiotic agent to reverse HFD‐induced gut microbiota dysbiosis and help us to gain a better understanding of the mechanisms governing the various melatonin beneficial effects.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
