Figure 2From: Downregulation of peroxisome proliferator-activated receptors (PPARs) in nasal polyposisExpression levels of PPARα, PPARβδ and PPARγ in polyps from 7 patients with bilateral nasal polyposis before (control) and after steroid treatment. Levels of PPAR mRNA are calculated in relation to 100,000 mRNA molecules of β-actin. Bold lines represent the median values. The PPARγ levels were reduced following steroid treatment (*p < 0.05).Back to article page
