摘要： Adipogenesis is important in the development of fat deposition. Evidence showed that plant microRNAs (miRNAs) could be absorbed by the digestive tract and exert regulatory effects on animals' physiological processes. However, the regulation of plant miRNA on host lipogenesis remains unknown. This study explored the potential function of plant miRNA, miR167e-5p, in adipogenesis in vitro. The presentation of plant miR167e-5p improved lipid accumulation in 3T3-L1 cells. Bioinformatics prediction and luciferase reporter assay indicated that miR167e-5p targeted beta-catenin. MiR167e-5p could not only negatively affect the expression of beta-catenin but also showed a positive effect on several fat synthesis-related genes, peroxisome proliferator-activated receptor gamma (Ppary), CCAAT/enhancer-binding protein alpha (Cebp alpha), fatty acid-binding protein 4 (Ap2), lipolysis genes, adipose triglyceride lipase (Atgl), and hormone-sensitive lipase (Hsl) messenger RNA levels. Meanwhile, lipid accumulation and the expression of the beta-catenin and other five fat synthesis-related genes were recovered to their original pattern by adding the miR167e-5p inhibitor in 3T3-L1 cells. The immunoblot confirmed the same expression pattern in protein levels in beta-catenin, PPAR-gamma, FAS, and HSL. This research demonstrates that plant miR167e-5p can potentially affect adipogenesis through the regulation of beta-catenin, suggesting that plant miRNAs could be a new class of bioactive ingredients in adipogenesis.
