Abstract

Diet is a crucial factor for preventing most diseases. Edible plant extracts are known to contain exosome-like nanoparticles, in which food-derived plant microRNAs are included and may serve as a novel functional component in human health. Here, we demonstrated that hvu-MIR168-3p included in the nanoparticles of rice aleurone cells down-regulated the expression of the genes related to mitochondrial electron transport chain complex I in human cells. Subsequently, hvu-MIR168-3p enhanced protein and RNA expression levels of glucose transporter I and caused a decrease in the blood glucose level, which findings were obtained by in vitro and in vivo experiments, respectively. These findings suggest that a cross-kingdom relationship between plants and humans with respect to hvu-MIR168-3p exists and may contribute to preventive medicine for GLUT1-related dysfunctions including glucose metabolism, aging, and tumor immunology.
