Abstract:
Inflammation is the most important link between obesity and type 2 diabetes (T2D). Although milk fat globule-epidermal growth factor 8 (MFG-E8) is a key mediator in anti-inflammatory responses, its role in obesity and diabetes is not yet completely understood. We aimed to measure MFG-E8 serum levels and to explore the role of MFG-E8 in obesity and T2D. Fasting serum MFG-E8 levels were quantified by enzyme-linked immunosorbent assay for 168 individuals, whose oral glucose tolerance test was conducted, and levels of inflammatory factors, including tumor necrosis factor-α (TNF-α) and C-reactive protein, were measured. The participants were subdivided into 66 newly diagnosed T2D individuals, 44 impaired glucose tolerance (IGT) subjects and 58 healthy controls. Their characteristics were further classified as lean or nonlean for investigation. MFG-E8 levels were significantly higher in T2D subjects than in healthy controls (P = 0.028). Decreased levels of MFG-E8 were found in overweight or obese individuals, compared to those in lean subjects, in both the T2D and IGT groups (P < 0.001). Interestingly, MFG-E8 levels showed a negative correlation with body mass index (BMI) and TNF-α levels in the total population and the T2D subgroup. Further, BMI and TNF-α concentrations were found to be independent predictors of MFG-E8 levels in all subjects. MFG-E8 levels are elevated in T2D but suppressed by increased adipose tissues, thereby allowing inflammatory factors to rise to high levels. MFG-E8 may serve as a potential biomarker for obesity and T2D in the clinical setting. © 2017 IUBMB Life, 69(2):63-71, 2017.

Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...
