Abstract
Aim of the studyTo study the cross-border regulation of immunity and energy metabolism by ginseng miRNA156, and to provide a new perspective for further exploring the possibility of ginseng miRNA156 as a pharmacodynamic substance. Materials and methodsCombined with the previous research results of our research group, miRNA156 with high expression in blood sequencing of intragastrically administered with ginseng decoction was selected. Bioinformatics analysis was performed on the selected differential miRNA156. The target genes of differential miRNA156 were mainly enriched in metabolic, immune and other signaling pathways. According to the analysis results, the experimental part will use qi deficiency fatigue model and RAW264.7 cells. The contents of lactic acid (LA), creatine kinase (CK), blood urea nitrogen (BUN), lactate dehydrogenase (LD), liver glycogen (LG), muscle glycogen (MG), interleukin 4 (IL-4), matrix metallo-proteinase 9 (MMP-9), superoxide dismutase (SOD), malondialdehyde, phosphor-enolpyruvate carboxykinase (PEPCK), glucose-6-phosphatase (G6pase), nitric oxide (NO) and tumor necrosis factor-α (TNF-α) were measured after administration of miRNA156. ResultsGinseng miRNA156 can accelerate the removal of metabolic waste during exercise. Increase the glycogen reserve in, provide energy for the body, regulate the activity of key gluconeogenesis enzyme phosphorus, improve the energy metabolism system of, and enhance the endurance of fatigue mice. The contents of matrix metalloproteinase 9, superoxide dismutase and malondialdehyde were affected, and the content of TNF-α in the supernatant of RAW264.7 cells was significantly increased, which had certain antioxidant capacity and potential immunomodulatory effects. ConclusionGinseng miRNA156 has a certain regulatory effect on the energy metabolism and immune function of mice, which makes it possible to regulate the cross-species regulation of ginseng miRNA in theory, provides ideas for ginseng miRNA to become a new pharmacodynamic substance.
