Inducible microRNA-214 contributes to the suppression of NF-κB-mediated inflammatory response via targeting myd88 gene in fish.

ABSTRACT: Upon recognition of bacterial pathogens by pattern recognition receptors, cells are activated to produce pro-inflammatory cytokines and type I IFN by multiple signaling pathways. Every step of the process must be precisely regulated to prevent dysregulation. MicroRNAs (miRNAs) have been shown to be important regulators with profound effects on inflammatory response. Nevertheless, the miRNA-mediated regulatory mechanism remains unclear in fish species. Here, we addressed the role of miiuy croaker miR-214 in the bacteria triggered inflammatory response. miR-214 could significantly be up-regulated by Vibro harveyi and LPS stimulation. Up-regulating miR-214 subsequently inhibits the production of inflammatory cytokines by targeting myd88 to avoid excessive inflammation. Moreover,
