ABSTRACT
<p><b>OBJECTIVE</b>To investigate the relationship between cyclin D2 and P210(BCR/ABL) tyrosine kinase in chronic myelogenous leukemia (CML).</p><p><b>METHODS</b>RT-PCR, Western blot and flow cytometry were performed to detect the expression of cyclin D2 in K562 cells and in K562-ib-eGFP cells which express intracellular single-chain antibody (sFv, intrabody) against ABL tyrosine kinase domain.</p><p><b>RESULTS</b>Cyclin D2 expression in K562-ib-eGFP cells was 18.90% which was lower than that of control K562 cells (48.10%), and the number of S-phase cells in K562-ib-eGFP was 40.40% which was much lower than that in K562 cells (64.34%).</p><p><b>CONCLUSION</b>Cyclin D2 is a potential down-stream signal molecule of the p210(BCR/ABL) tyrosine kinase in CML. The altered expression of cyclin D2 may contribute to the over proliferation of CML cells.</p>
