Expression of SOCS1 Protein in Endotoxin-Tolerant Mouse Model and Its Regulation Mechanism by mir-150

In order to investigate the expression of Suppressor of Cytokine Signaling 1 (SOCS1) and its regulatory mechanism by mir-150 in a lipopolysaccharide (LPS) tolerant mouse model of endotoxin, a total of 60 male BALB/C mice were randomly divided into 2 groups. The LPS is used to construct the endotoxin resistant mouse model and the mice are included in the model group (n = 30), 0.9% sodium chloride injection is used to construct the normal control group (n = 30). And tumor necrosis factor-α (TNF-α) is determined by Elisa to determine whether the model was successfully constructed. The correlation between SOCS1 protein and mir-150 is analyzed by the Pearson correlation coefficient. In the experiments, the results show that the expression of TNF-α in the macrophage fluid of the model group is significantly decreased (P < 0.05), indicating that the endotoxin tolerance mouse model is successfully constructed, so the secretion of TNF-α is reduced.
