摘要： The aim of this paper was to study the differential gene expression of giant cell tumor of bone (GCTB) by gene chip technology. Total RNA of 8 fresh GCTB specimens (Jaffe I∶6 cases, II∶1 case, III∶1 case; Campanacci I∶6 cases, II∶1 case, III∶1 case; Enneking Staging G T M : 5 cases, G T M : 2 cases, G T M : 1 case) and 4 normal bony callus specimens (the control group) were extracted and purified to get mRNA and then reverse transcribed to complementary DNA, respectively. Microarray screening with a set of 8064 human cDNA genes was conducted to analyze the difference among the samples and the control. The hybridization signals were scanned. The gene expression disparity between the GCTB samples and normal bony callus was significantly different ( <0.01), and the disparity of over 5-fold was found in 47 genes in the GCTB specimens, with 25 genes up-regulated and 22 down-regulated including the extracellular matrix and transforming-related genes, oncogene and its homolog genes, cytokine and its receptor genes. Specific gene spectrum associated with GCTB can be identified by cDNA microarray, which will be the foundation of progressive etiology elucidation, diagnosis and treatment of GCTB.
