Abstract (original English)
The global obese population accounts for approximately 30% of the total population and continues to increase. White adipocytes, which accumulate in the body for energy storage, are associated with obesity. Mechanisms that activate browning of white adipocytes are an attractive therapeutic target for obesity and metabolic disorders. Exosomes are nano-sized biovesicles that play a role in cell-to-cell communication though the transfer of cargos such as microRNAs. Although milk exosomes contain many endogenous microRNA molecules, the role of microRNAs in milk exosomes is limited. Therefore, the aim of this study was to investigate the effects of milk exosomes on the browning of white adipocyte. Mouse pre-adipocytes (3T3-L1) and human adipose-derived stem cells (hADSCs) were differentiated and exposed to milk exosomes. Compared to control, milk exosomes promoted the expression of thermogenic genes and cellular mitochondrial energy metabolism in both 3T3-L1 cells and hADSCs. Additionally, milk exosomes were orally administered to mice fed a high-fat diet. As the intake of milk exosomes increased, the mice's body weight decreased. Milk exosomes also increased the protein levels of thermogenic genes and mitochondrial-related genes in mouse adipose tissue. The overexpression of miR-11987, which is abundant in milk exosomes, in both 3T3-L1 cells and hADSCs led to the increased expressio
