Enhanced expression of SAM-pointed domain-containing Ets-like factor in Chronic rhinosinusitis with nasal polyps

Objective/Hypothesis Chronic rhinosinusitis with nasal polyps (CRSwNP) is characterized by significant goblet hyperplasia and mucus hypersecretion. However, the molecular mechanism underlying mucin overexpression in CRSwNP has not been well characterized. This study sought to assess the expression of SAM-pointed domain-containing Ets-like factor (SPDEF) and its regulation of mucin production in CRSwNP patients. Study design Prospective...
