Abstract:
Objective To study the difference of the peripheral blood lymphocyte gene expression in the glioblastoma patients and the normal subjects by the gene chip engineering technique. Methods The human gene expression spectrum chip containing 13 824 cDNA was used to detect the gene expression in the peripheral blood lymphocytes of 23 glioblastoma patients and 40 normal persons. The lymphocyte mRNA in the glioblastoma patients and healthy subjects was withdrawn. The cDNA probe with the different fluorescein was made by reverse transcription. The probe and the chip were hybridized. The fluorescence intensity was scanned and digitized,and gene expression was compared between the two groups. Results The peripheral blood lymphocytes in the glioblastoma patients had 96 genes to present the difference expression with that of normal subjects,including 25 upregulated genes and 71 downregulated genes. Conclusion The gene expression in the peripheral blood lymphocytes of glioblastoma patients and normal subjects exists difference. The lymphocyte DNA union,the abnormal function of transcription and signal conduction are the possible reasons for the different immune function between the glioblastoma patients and the healthy subjects.
