Effect of anti-gut inflammatory agent on insulin resistance and lipid profile of mice fed different diets
Abstract
Purpose: To further explore the effect of 5-aminosalicylic acid (5-ASA) treatment on lipid levels in mice fed different diets.
Methods: Groups of 9 - 10 mice each were randomly assigned to 6 different diets, low-fat diet (LFD) with or without 5-ASA, high-fat diet (HFD) with or without 5-ASA, and high-fat high-cholesterol diet (HFC) with or without 5-ASA for 12 weeks.
Results: There were changes in gut microbiota of 5-ASA-treated mice, although gut permeability was similar between treated and non-treated groups. The level of fasting blood glucose, fasting plasma insulin and the curve of glucose tolerance test (GTT) in mice fed LFD, HFD or HFC diet were not affected by 5-ASA treatment. Although plasma lipid levels were similar between 5-ASA consuming and non-5-ASA groups in mice fed LFD and HFD, improved lipid profile was seen in mice that received HFC+5-ASA when compared with mice fed only HFC.
Conclusion: These results indicate that targeting gut inflammation and dysbiosis with 5-ASA neither improves gut barrier nor insulin resistance (IR). Thus, results from therapies for metabolic disorder based on anti-gut inflammation should be interpreted with caution.
