The liver X receptor alpha (LXRα or NR1H3) mRNA is translated to yield NR1H3 protein. MicroRNAs miR-1, miR-206 and miR-613 have been identified as negative regulators of NR1H3 expression and lipogenesis in the liver (Zhong D et al. 2013; Ou Z et al. 2011). Interestingly, miR-206 also regulates NR1H3 in macrophages but in an opposing manner relative to liver (Vinod M et al. 2014). Stably overexpressing miR-206 in THP-1 human macrophages revealed an up-regulation of NR1H3 and miR-206 knockdown led to a down-regulation of NR1H3 and its target genes (Vinod M et al. 2014).
