Abstract:
AIM: To find new gene function associate with active lupus nephritis (LN) through study on the difference in gene expression of peripheral blood mononuclear cells between LN patients and healthy controls by gene chip. METHODS: The CSC-GE-80 chip containing 8 000 spots of cDNAs were used to investigate the difference of the expression. Both the total RNA from peripheral blood mononuclear cells of active LN patients and healthy donors were reversely transcribed to cDNA with the incorporation of fluorescent( cy3 and cy5) labeled dCTP to prepare the hybridization probes. After hybridization, the gene chip was scanned for the fluorescent intensity. The differentially expressed genes were screened. We repeated that in three groups of LN patients and healthy controls, respectively, and only the genes that have differential expression in all three chips were considered associated with LN. RESULTS: 75 genes were identified to be differently expressed in all three groups of LN patients as compared with healthy controls, including 42 up-regulated genes and 33 down-regulated ones. CONCLUSION: The present study represents a global view of gene expression of LN and provides important clues for further study of LN related genes. And it also suggests defensin ? 1, S100A8, S100A9 may be involved in the pathogenesis of LN.
