[Changes in gene expression profiles in multiple myeloma cells after knocking-down SNF5, a core subunit of SWI/SNF complex].

OBJECTIVE

To investigate the changes in the gene expression profiles in a multiple myeloma cell line after knocking-down the expression of SNF5, a core component of the SWI/SNF chromatin remodeling complex.

METHODS

The total RNA were extracted from tetracycline-inducible SNF5 knockdown (KD) cell line derived from KM3 cells for gene expression profiling by affymetrix microarray and bioinformatic analysis.

RESULTS

Knockdown of SNF5 inhibited KM3 cell proliferation. A total of 545 genes were found to be differentially expressed in the cells with SNF5 knockdown, among which 214 were up-regulated and 331 were down-regulated.

CONCLUSIONS

SNF5 is essential for the growth of multiple myeloma cells and can regulate the expression of the genes associated with cell growth and apoptosis.
