MicroRNA-183 regulates lipopolysaccharide-induced oxidative stress of hippocampal neurons by targeting the fibronectin 1 gene. Neurosci Lett 2020; 725:134902. [PMID: 32165261 DOI: 10.1016/j.neulet.2020.134902] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2019] [Revised: 02/27/2020] [Accepted: 03/07/2020] [Indexed: 12/24/2022]
Abstract
Oxidative stress is implicated in the initiation and progression of human and animal diseases. MicroRNA (MiR) has been reported to be involved in the body's regulation to oxidative stress. We investigated if miR-183 regulates lipopolysaccharide (LPS)-induced oxidative stress in the hippocampus of weaned piglets. LPS-treated piglets had lower expression of miR-183 and higher expression of the fibronectin(FN)1 gene in their hippocampus than control piglets. The expression profiles of miR-183 and the FN1 gene in primary cultured rat hippocampal neurons exposed to LPS were consistent with those in the hippocampus of LPS-treated piglets. The LPS-induced expression of FN1 was reversed in hippocampal neurons by transfection with an miR-183 mimic. A luciferase reporter assay further demonstrated that the FN1 gene is a direct target of miR-183. Taken together, our results demonstrated that miR-183 regulates LPS-induced oxidative stress at least in part by targeting FN1.

Abstract
Despite much progress in microRNA (miRNA) research, information regarding the association between miRNAs and venous thromboembolism (VTE), especially in Asian patients, remains limited. This case-control study sought to determine the correlation between the presence of polymorphisms in the genes encoding the miRNAs miR-146a, miR-149, miR-196a2, miR-499, and VTE in Korean patients. We observed no statistically significant differences in the genotype frequency of miRNA polymorphisms between 300 control individuals and 203 VTE patients. However, we observed a significant association between three allelic combinations of miRNA polymorphisms and VTE risk. Overall, our findings suggest that specific miRNA polymorphisms are associated with the risk of VTE in a Korean population.
