OBJECTIVE
To study the effect of rutin on body weight and obesity-induced reproductive impairment in male mice.
METHODS
Twenty-four male mice were randomized equally into normal control group, high-fat diet group (HFD group), and HFD + rutin intervention group (HRU group). After 28 days of treatments, the testes and epididymis of the mice were collected for detection of total cholesterol (TC) and triglycerides (TG) levels and for pathological examinations with HE staining. The expressions of related genes was detected with real-time PCR, and Western blotting was used to detect the expression of Ucp1 protein in the samples.
RESULTS
After 28 days of treatments, the mean body weight was lower in mice with rutin intervention than in those in HFD group. The mice in HFD group showed significantly higher TG levels in the testis and epididymis and higher TC levels in the epididymis than those in the control and HRU groups. In HFD group, the testis and the epididymis displayed loosened structures with abnormalcell structure, and the number ofmature spermatozoa in the lumen was decreased and the mobility of the sperms was reduced; all these changes were significantly alleviated in HRU group. The expression levels of Ucp1 mRNA and protein increased (P<0.05) and the expressions of Mcp1 and TNF-α decreased significantly in the mice after rutin treatment (P<0.05).
CONCLUSIONS
Rutin can effectively inhibit rapid increase of body weight and protect against obesity-induced reproductive impairment in obese mice.
