Figure 1From: Downregulation of peroxisome proliferator-activated receptors (PPARs) in nasal polyposisExpression levels of PPARα, PPARβδ and PPARγ in biopsies of the nasal mucosa from 10 healthy volunteers (control) and 10 patients with symptomatic allergic rhinitis (allergic) together with biopsies of nasal polyps from 11 patients with bilateral nasal polyposis (polyp). Levels of PPAR mRNA are calculated in relation to 100,000 mRNA molecules of β-actin. Bold lines represent the median values. The expression of PPARα and PPARγ was lower in polyps than in normal nasal mucosa (**p < 0.01).Back to article page
