Inflammation is a complex biological process which alters the normal physiological function of the immune system resulting in an abnormal microenvironment that leads to several clinical complications. The process of inflammation is mediated through various intracellular signaling factors inside the cells. Apoptosis signal–regulating kinase 1 (ASK1) is an inflammation-derived kinase that controls the activation of other family of kinases such as p38 mitogen–activated protein kinases (p38 MAPKs), which mediates various the inflammatory processes. In this study, we cultured THP-1 macrophage cells to undergo inflammatory proliferation with LPS (1 μg/ml) and TNFα (10 ng/ml) stimulation. Initial in silico analysis was utilized to predict novel microRNAs (miRNAs) that target ASK1 signaling and its expression levels in LPS and TNFα stimulated THP-1 cells were estimated. Among the miRNAs, miR-532-3p showcased the highest binding affinity towards ASK1 kinase. We witnessed that transient transfection of miR-532-3p diminished the levels of ASK1 and downstream phosphorylation/translocation of p38 MAPK. Furthermore, direct targeting of ASK1 resulted in regulation of uncontrolled release of cytokines (TNFα, IL-6, and IL-23) and chemokines (GM-CSF and MIP-2α). Overall, we suggest that miR-532-3p attenuates the pro-inflammatory nature of macrophages by targeting ASK1/p38 MAPK signaling pathway and can be used as a molecular intervention for treating inflammatory diseases. © 2020, Springer Science+Business Media, LLC, part of Springer Nature.
