title: Expression of ADAM17 and ADAM10 in nasal polyps.
abstract: The "a disintegrin and metalloproteases" (ADAMs) are a multifunctional gene family that contribute to the homeostasis of the extracellular matrix, transduction of specific intracellular signals, organogenesis, inflammation, tissue remodeling, adhesion, and cell migration. ADAM17 is the best-characterized of the "sheddases," and its putative substrates are widespread, including various inflammatory modulators. ADAM10 is the most similar to ADAM17 in terms of protein sequence and the structural properties of their catalytic domains. The objective of this work was to assess the roles of ADAM17 and ADAM10 in nasal polyps (NPs) by measuring their expression.
  
  
  
  The expression of ADAM10 and 17 was investigated in NPs at endonasal sinus surgery (n = 15) and compared with that in inferior turbinate mucosa samples obtained from nonallergic hypertrophic rhinitis patients (n = 15). Tissue samples were analyzed by real-time polymerase chain reaction (PCR), Western blotting, and immunohistochemical staining.
  
  
  
  The ADAM17 messenger RNA (mRNA) and protein levels were significantly higher in the inferior turbinate than in NPs (p < 0.05). The ADAM10 mRNA and protein levels did not differ significantly between NPs and inferior turbinates (p > 0.05). ADAM10 and ADAM17 were expressed primarily in inflammatory cells, submucosal glandular cells, and lining epithelial cells.
  
  
  
  ADAM17 may contribute to the development of NPs in contrast to ADAM10, based on their expression patterns. It may be important to discover the role of ADAM17 in the development of NP and helpful to examine the specific mechanism of the development of NPs.
