ABSTRACT
OBJECTIVE@#To study the expression of insulin-like growth factor-1 receptor(IGF-1R) in nasal polyps and its relationship with allergic rhinitis.@*METHOD@#The mRNA and protein expression of IGF-1R in 40 cases (20 cases with allergic rhinitis and 20 cases without) nasal polyps tissue (the CRSWNP group) and 20 middle turbinate tissue samples (the control group) were examined by fluorescence quantitative polymerase chain reaction (FQ-PCR) and immunohistochemistry.@*RESULT@#The positive staining rate of IGF-1R protein of nasal polyps tissue is 70.8% and that of control is 12.3%, the expression of IGF-1R mRNA of nasal polyp is 0.748 +/- 0.111,which is significant higher than that of the control group is 0.107 +/- 0.208 (P < 0.01). No significant difference of the expression of IGF-1R mRNA between with and without allergic rhinitis cases and between with and without endoscopy sinus surgery history cases in the CRSWNP group.@*CONCLUSION@#The overexpression of IGF-1R maybe play important roles in the formation of nasal polyp. Hypersensitivity reaction type I mediated by IgE has no contribution to the overexpression of the IGF-1R.
