Composite real time PCR data. Shown are means + SEM, n = 2 for non-CRS (0.533 ± 0.231), 5 for CRSsNP (2.267 ± 1.215), and n = 5 for CRSwNP (1.278 ± 0.413). There was no statistically significant difference among the groups. CRS: chronic rhinosinusitis; s: sine; w: with; NP: nasal polyposis SOAT1: sterol O-acyltransferase 1; RPLP0: ribosomal protein, large, P0
