[Screening of differentially expressed genes of allergic rhinitis with asthma].

Objective: To detect the differentially expressed genes of allergic rhinitis(AR) with asthma and screen the pathogenic genes. Method: Eight nasal mucosa tissue samples from patients with nasal septum deviation (healthy control group), eight nasal mucosa tissue samples from patients with allergic rhinitis（AR） and eight nasal mucosa tissue samples from patients with AR and asthma were collected. Allergy & Asthma PCR Array was used to analyze allergy related genes expression level. Result: Compared to the control group, there are 84 related genes were found and 15 genes were up-regulated, 69 genes were down-regulated. Furthermore, there are 17 genes（ADAM33, BCL6, IFNGR2, IL12A, IL12B, IL13RA1, IL17A, IL31, IL4R, IL5, KIT, LTB4R, MS4A2, RORC, STAT5A, STAT6, TBX21） differentially expressed. Compared AR with asthma group to the AR group, there was 1 gene differentially expressed(RORC). Conclusion: ADAM33, BCL6, IFNGR2, IL12A, IL12B, IL13RA1, IL17A, IL31, IL4R, IL5, KIT, LTB4R, MS4A2, RORC, STAT5A, STAT6, TBX21 are the possible pathogenic genes of AR with asthma. RORC may be the specific marker gene in asthma induced by allergic rhinitis.
