    Journal: Zhonghua Jie He He Hu Xi Za Zhi; 2005 Mar; 28(3):149-53. PubMed ID: 15854407.
    Abstract:
    OBJECTIVE: To study genes that differentially expressed in peripheral blood eosinophils of patient with asthmatic. METHODS: Total RNA extracted from eosinophils of patient at the time of exacerbation was taken as the tester and the total RNA from eosinophils of the same patient after improvement as driver. The ds cDNA was synthesized by SMART PCR cDNA Synthesis technology. The differentially expressed genes were obtained by suppression subtractive hybridization (SSH) technology and were further identified by Southern blot. RESULTS: Twelve differentially expressed genes including transformation growth factor beta activated kinase like (TAK1L) protein, cGMP gated channel protein were obtained. CONCLUSION: Increased expression of these genes were involved in the regulation of proinflammatory response, signal transduction, energy metabolism and cell apoptosis, which may help to clarify the molecular mechanism of eosinophils in asthma and may provide the theoretical base for finding out the new medicines towards eosinophils.
