Consistently, we found that epithelial MEX3B mRNA levels were positively associated with tissue edema scores (Figure 9D), but epithelial TGFBR3 mRNA levels were associated negatively (Figure 9E) with edema in eosinophilic CRSwNP participants. The gene discussed is TGFBR3; the disease is chronic rhinosinusitis with nasal polyps.
