ABSTRACT
<p><b>OBJECTIVE</b>To investigate the inhibition effect of leukemic bone marrow stromal cells (BMSCs) on daunorubicin (DNR) induced apoptosis of human Jurkat cell line, and analyze the differentially expressed genes between Jurkat cells cocultured with leukemic BMSCs or without.</p><p><b>METHODS</b>Suppression subtractive hybridization (SSH) was employed to establish subtracted cDNA library of differentially expressed genes in Jurkat cells cocultured with leukemic BMSCs and DNR. The cDNA fragments were sequenced and analyzed.</p><p><b>RESULTS</b>The differentially expressed gene cDNA library was successfully developed. Primary screening was done by reverse Northern hybridization. Thirty up-regulated and 22 down-regulated cDNA fragments were isolated and sequenced. Analysis and comparison were performed in GenBank using BLAST. These genes are related to cell cycle regulation, cell apoptosis and energy metabolism.</p><p><b>CONCLUSION</b>Leukemic BMSCs influence gene expression of Jurkat cells. The resulting differentially expressed genes might be associated with the protection of leukemic cells by BMSCs from injury.</p>
