Fig. 4. Pendrin expression correlated with IL-13 mRNA in sinonasal tissues.
Gene expression for IFNγ (A), IL-13 (B) and IL-17A (C) in sinonasal tissues was determined by real-time PCR. The relationship between pendrin and IL-13 was analyzed in mRNA samples by Spearman rank correlation (D). *p<0.05, **P<0.01, ***p<0.001
