Uncarboxylated osteocalcin (GluOC), a bone-derived hormone, regulates energy metabolism by stimulating insulin secretion, pancreatic β-cell proliferation, and adiponectin expression in adipocytes. Previously, we showed that long-term intermittent or daily oral administration of GluOC reduced the fasting blood glucose level, improved glucose tolerance, and increased the fasting serum insulin concentration as well as pancreatic β-cell area in female mice fed a normal or high-fat, high-sucrose diet. We have now performed similar experiments with male mice and found that such GluOC administration induced glucose intolerance, insulin resistance, and adipocyte hypertrophy in those fed a high-fat, high-sucrose diet. In addition, GluOC increased the circulating concentration of testosterone and reduced that of adiponectin in such mice. These phenotypes were not observed in male mice fed a high-fat, high-sucrose diet after orchidectomy, but they were apparent in orchidectomized male mice or intact female mice that were fed such a diet and subjected to continuous testosterone supplementation. Our results thus reveal a sex difference in the effects of GluOC on glucose homeostasis. Given that oral administration of GluOC has been considered a potentially safe and convenient option for the treatment or prevention of metabolic disorders, this sex difference will need to be taken into account in further investigations.

Abstract Background Type 2 Diabetes (T2D) has become one of most common and harmful chronic diseases worldwide. T2D is characterized as insulin resistant and is often associated with unhealthy dietary habits. The present study assessed the effects of freeze-dried Saskatoon berry powder (SBp) and cyanidin-3-glucoside (C3G, an anthocyanin enriched in SBp) on metabolism, inflammatory markers and gut microbiota in high fat-high sucrose diet (HFHS) diet induced insulin resistant mice. Results Male C57 BL/6J mice received control, HFHS, HFHS + SBp (8.0 g/kg body weight/day) or HFHS + C3G (7.2 mg/kg/day, equal amount of C3G in 8.0 g/kg/day SBp) diet for 11 weeks. HFHS diet significantly increased the levels of glucose, cholesterol, triglycerides, insulin resistance and inflammatory mediators in plasma. The results of 16S rRNA gene sequencing demonstrated that HFHS diet increased the ratio of Bacteroidetes/Firmicutes (B/F) phylum bacteria and an elevated abundance of Muriculaceae family bacteria in the feces of mice. SBp or C3G supplementation attenuated HFHS diet-induced disorders in metabolism and inflammatory markers, and increased B/F ratio and Muriculaceae abundance in mouse gut compared to HFHS diet alone. The abundance of Muriculaceae in the gut microbiota negatively correlated with body weight, glucose, lipids, insulin resistance and inflammatory mediators in mice. The results of functional predication analysis suggest that HFHS diet upregulated the genes of gut bacteria involved in inflammation-related cellular processes, and inhibited bacteria involved in metabolism. SBp and C3G partially neutralized the alterations induced by HFHS diet in gut microbiota implicated in metabolism or inflammation. Conclusion The findings of the present study suggest that SBp is a potential prebiotic food mitigating Western diet-induced disorders in metabolism, inflammation and gut dysbiosis, and C3G possibly contributes to the beneficial effects of SBp.

Astaxanthin n-octanoic acid diester (AOD) is a type of astaxanthin connecting medium-chain fatty acids with a more stable structure. In this study, we examined the role of AOD in ameliorating insulin resistance (IR) induced by a high-fat and high-sucrose diet (HFD) as well as its effect on modulating gut microbiota in mice, with free astaxanthin (AST) as a comparison. Four groups of male C57BL/6J mice (6 weeks old; n = 10 per group) were fed with a normal control diet (NC), HFD orally administered with AOD, AST (50 mg/kg body weight), or vehicle for 8 weeks. AOD improved glucose tolerance, IR, systematic and intestinal inflammation, and intestinal integrity better than AST. Further, both AOD and AST modulated gut microbiota. A significantly higher abundance of Bacteroides and Coprococcus was found in AOD than in AST, and the predicted pathway of carbohydrate metabolism was significantly impacted by AOD. Overall, AOD may play a role in alleviating IR and inflammation with the modulating effect on microbiota in HFD-fed mice. Our findings could facilitate the development of AOD as a bioactive nutraceutical and more stable alternative to AST.
