  •   Objective  To investigate the role and potential mechanism of microRNA-544 (miRNA-544) in lipopolysaccharide (LPS)-induced liver injury in mice with sepsis, and to provide a new target for the treatment of liver injury in sepsis.  Methods  A total of 40 C57BL/6J mice were randomly divided into control group (intraperitoneal injection of normal saline), model group (intraperitoneal injection of LPS at a dose of 5 mg/kg), agonist group (intraperitoneal injection of LPS and miR-544 agonist at a dose of 5 mg/kg), and miR-544 inhibitor group (intraperitoneal injection of LPS and miR-544 inhibitor at a dose of 5 mg/kg), with 10 mice in each group. An automatic biochemical analyzer was used to measure the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total bilirubin (TBil) in serum and the liver; Western blot was used to measure the expression levels of monocyte chemotactic protein-1 (MCP-1), CD16/32, and proteins associated with the NF-κB signaling pathway in the liver; q-PCR and ELISA were used to measure the expression levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-1β (IL-1β) in serum. A one-way analysis of variance was used for comparison between multiple groups, and the least significant difference t-test was used for further comparison between two groups.  Results  Compared with the control group, the model group of LPS-induced sepsis had a significant reduction in the expression level of miR-544 in serum and liver tissue (P<0.01), significant pathological changes of the liver (such as inflammatory cell infiltration and central vein congestion), and significant increases in the levels of liver injury markers (ALT, AST, and TBil) in serum and the liver (all P<0.001), the expression levels of inflammatory factors (MCP-1, CD16/32, TNF-α, IL-6, and IL-1β) (all P<0.01), and the phosphorylation levels of key proteins of the NF-κB pathway (p-IKK, p-I-NF-κ, and p-p65) (all P<0.01). Compared with the model group, the miR-544 inhibitor group had a significant reduction in the expression level of miR-544 in serum and liver tissue (P<0.01), aggravated pathological changes of the liver, and significant increases in the levels of liver injury markers and inflammatory factors (ALT, AST, TBil, MCP-1, CD16/32, TNF-α, IL-6, and IL-1) (all P<0.05), as well as significant increases in the phosphorylation levels of key proteins of the NF-κB pathway (p-IKK, p-I-κB-α, and p-p65) (all P<0.01). On the contrary, the miR-544 agonist group had a significant increase in the expression level of miR-544 in serum and liver tissue (P<0.01), significant alleviation of liver pathological changes, and significant reductions in the levels of liver injury markers and inflammatory factors (ALT, AST, TBil, MCP-1, CD16/32, TNF-α, IL-6, and IL-1β) (all P<0.05), as well as significant reductions in the phosphorylation levels of key proteins of the NF-κB pathway (p-IKK, p-I-κB-α, and p-p65) (all P<0.05).  Conclusion  This study shows that miR-544 can alleviate LPS-induced liver injury in mice with sepsis by inhibiting the expression of inflammatory-related proteins and the activation of the NF-κB signaling pathway.
