Abstract:
OBJECTIVE: To compare the changes of gene expression profiles of multiple myeloma cell line RPMI 8226 before and after 24-hour intervention of arsenic trioxide. METHODS: The responses of the RPMI 8226 cells to arsenic trioxide were determined with cDNA microarray which included 4,096 different human genes. RESULTS: Of these 4,096 genes, the expressions of 273 genes were altered significantly at mRNA level. The expressions of 121 genes were up-regulated while the expressions of 152 genes were down-regulated. CONCLUSION: The effect of arsenic trioxide on RPMI 8226 cells is related to changing the expression levels of a number of genes. ZFYVE16, ALK1 and TXNIP genes may play important roles in apoptosis and differentiation of RPMI 8226 cells.
