[Correlation of HSP90 mRNA expression with migration ability of human multiple myeloma cells].
This study was aimed to investigate the correlation of heat shock protein 90 (HSP90) expression with migration ability of human multiple myeloma cells. The HSP90 mRNA expression and migration change of human multiple myeloma cell line (U266) were detected by RT-PCR and Transwell chamber respectively after treatment of U266 cells with final concentration 50, 100, 150, 200 nmol/L of bortezomib (proteosome inhibitor) for 4 hours. The results indicated that along with the increasing of bortezomib concentration, the expression level of HSP90alpha mRNA in U266 cells was enhanced, while no obvious increase of HSP90beta mRNA expression was observed in spite of statistical difference as a whole (p<0.05), but with the increasing of drug concentration in cells, their migration ability gradually decreased (p<0.05). It is concluded that the correlation of HSP90 expression with migration ability of human multiple myeloma cells exists.
