Abstract:
AIM: To investigate the relationship between inflammatory cell infiltration and proto-oncogenes expression in asthma. METHODS: Guinea pigs were used as asthma models challenged by ovoglobulin. Dot-blot, Northern-blot and immunochemical techniques were used to detect the expression of c-fos, c-myc, c-jun and c-sis. Inflammatory cell infiltration was showed by pathologic study.RESULTS: c-fos and c-myc mRNA could not be detected or expressed at very low level in control group. Those were greatly increased after the animals are challenged by ovoglobulin. Immunochemical study showed that Fos, Myc, Jun and Sis expressed at low level in control group, and those were increased after the challenge. There was little inflammatory cell infiltration in control group. Lymphocyte, neutrophil and eosinophil were detected immediately after the challenge, a great number of inflammation cells could be seen after 12-24 h of the challenge. Majority of neutrophil and eosinophil were under mucosa or in epithelium in airway. CONCLUSION: Oncogenes expression had strong relationship with airway inflammation.
