DUSP1 and asthma: In addition, gene expression analysis in peripheral blood mononuclear cells derived from allergic asthmatic and healthy school-age children showed that the expression of an anti-inflammatory gene, dual-specificity phosphatase-1 (DUSP1) and its specific H4 acetylation, which is associated with the anti-inflammatory effects of asthma-therapeutic glucocorticosteroids, was significantly lower in asthmatic children than in healthy ones [33].
