Sex-specific association between the gut microbiome and high-fat diet-induced metabolic disorders in mice.

ABSTRACT: BACKGROUND:Accumulating evidence indicates that high-fat diet (HFD)-induced metabolic disorders are associated with dysbiosis of the gut microbiota. However, the sex-specific characteristics of the gut microbiota and its association with a sexually dimorphic response to a HFD remain unclear. METHODS:Male and female mice were randomly assigned to receive a chow diet (CD) or HFD for 12 weeks. A group of HFD mice were pretreated with antibiotic cocktails for 4 weeks. Body weight, insulin sensitivity and the levels of serum metabolic parameters (blood glucose and insulin) were evaluated. 16S rRNA gene sequencing was performed to analyze the composition of the gut microbiota. RESULTS:HFD-induced body weight gain (BWG) was higher in male mice than in female mice. While insulin resistance was inc
