Fig. 1From: Recent exposure to ultrafine particles in school children alters miR-222 expression in the extracellular fraction of salivaCorrelation plot between recent UFP exposure and miR-222 and miR-146a. Plotting the miR-222 expression levels from the salivary extracellular fraction for the recent UFP exposure shows a positive association with both indoor (left) and outdoor (right) UFPBack to article page
