Abstract

Conclusion The reduced expression of these apoptosis factors in CRSwNP could be related to higher proliferation and perpetuation of inflammatory cells hindering the control of the disease. A better understanding of the possible influence of apoptosis factors on CRSwNP could be a rationale for future therapies.

Highlights

  • The inflammatory process in chronic rhinosinusitis with nasal polyps (CRSwNP) has been extensively studied

  • The molecular assessment of mechanisms involved in apoptosis might shed light on the pathogenesis of CRSwNP

  • We observed significantly lower expression of p53 and caspases 3 and 9 genes in patients with CRSwNP compared to the controls, while caspase 7 expression was expressed in both groups
