As basal cell hyperplasia is a hallmark of nasal polyps, we detected increased expression of basal cell marker in nasal polyps compared with the control (although only the Padj value of S100A2 was less than 0.05); however, the suppression caused by GC was not significant both in the Responder and Non-responder groups. This evidence concerns the gene S100A2 and Nasal polyposis.
