ht In the present investigation, although inflammation is present within both the nasal floor and ethmoid sinus of patients with CRSsNP, the inflammatory gene and pathway expression profiles manifest differently across the two subsites. There were 46 transcripts that were significantly different between the anterior ethmoid sinus mucosa and the floor of the nose using a cut-off of a >=4-fold change was implemented and presented (Gene Expression Omnibus contains the full dataset). These findings may provide useful insight into how sinus mucosa differs in its inflammatory response from nasal floor mucosa, while accounting for site-dependent differences in the inflammatory profile of patients with CRS.
