- This study evaluated the beneficial effects of fructooligosaccharide (FOS) intake from Aureobasidium pullulans using poloxamer-407 (PX-407) induced type 2 diabetes mellitus (T2DM) in rat. Administration of FOS enhanced enzymatic activities of catalase and glutathione reductase in a dose-dependent manner. Significant reduction in fasting plasma triacylglycerol and very low-density lipoprotein level coupled with slight increase in fasting plasma insulin level was observed. Significant decrease in severe glucosuria, proteinuria, blood creatinine, urea and advanced glycation end products was also observed. Supplementation of FOS increased glucagon like peptide-1 content as well as Bifidobacteria and Lactobacilli populations in the caecum. Molecular docking by Gold and Glide software revealed that three sugar types present in the FOS (1-kestose, nystose, and 1-β-fructofuranosyl nystose) are potent dipeptidyl peptidase-IV inhibitors as well as peroxisome proliferator-activated receptor-gamma agonists. This work indicates that FOS can be positioned as a nutraceutical product, beneficial in diabetes-associated metabolic abnormalities.
