ABSTRACT
OBJECTIVE:
Acute respiratory distress syndrome (ARDS) is greatly threatening human health with high morbidity and mortality. The pathogenesis of ARDS is closely related to the inflammatory response in patients. The micro-ribonucleic acid (miR)-155/nuclear factor-κB (NF-κB) signaling pathway is crucial in regulating the expression of inflammation-related genes. Therefore, the influences of miR-155/NF-κB signaling pathway on inflammatory factors in ARDS in neonatal pigs were explored in this study. MATERIALS ANDMETHODS:
The model of ARDS in neonatal pigs was established first. The expression levels of miR-155, NF-κB-related proteins, and inflammatory factors in model group and control group were detected, and their differences were compared. Moreover, after treatment with the miR-155/NF-κB signaling pathway inhibitor, the changes of the inflammatory factors expression in ARDS neonatal pigs were observed at different time points.RESULTS:
In the model group, the levels of miR-155 and NF-κB-related proteins were significantly increased, and the levels of inflammatory factors, including interleukin-1ß (IL-1ß), tumor necrosis factor-α (TNF-α), and IL-6, were also increased synchronously. However, the levels of IL-4 and IL-10 declined significantly. In addition, it was proved that after treatment with the inhibitor in model group the mRNA expressions of miR-155/NF-κB signaling pathway-related proteins were significantly inhibited, and the levels of IL-1ß, TNF-α, and IL-6 were also significantly inhibited (p<0.05). The levels of IL-4 and IL-10 remarkably rose after treatment with the inhibitor for 24 h (p<0.05).CONCLUSIONS:
The miR-155/NF-κB signaling pathway influenced the changes of inflammatory factors in ARDS in neonatal pigs, which might be a potential target for eliminating the inflammatory response after ARDS in neonatal pigs.
