PM2.5 increases the expression of glycolytic gene DALT in vitro and in vivo. A PM2.5 exposure enhanced the expression level of DLAT gene in BEAS-2B cells. B PM2.5 inhalation up-regulated DLAT gene expression in lung tissues of rats. C PM2.5 exposure promoted DLAT protein expression in BEAS-2B cells. Numerical numbers denoted the ratio of integrated optical density (IOD) to β-actin. D PM2.5 exposure increased DLAT protein expression in lungs of rats. *P < 0.05, **P < 0.01
