Identification of Rab6a as a New Target of microRNA-155 Involved in Regulating Lipopolysaccharide-Induced TNF Secretion.

Abstract:

:This study aims to provide experimental proof that Rab6a is an efficient target of microRNA-155 in regulating pro-inflammatory tumor necrosis factor (TNF) secretion stimulated by lipopolysaccharide (LPS) in macrophages. We identified Rab6a as a new target of microRNA-155 (miR-155) and found that overexpression of miR-155 decreased Rab6a expression at both protein and mRNA levels, which resulted in a significant reduction of TNF secretion induced by lipopolysaccharide stimulation. We have demonstrated that miR-155 can negatively regulate inflammatory TNF secretion in lipopolysaccharide stimulated macrophages, partly by targeting Rab6a, thereby providing new insights into the role of miR-155 in cytokine secretion in inflammatory macrophages.
