ABSTRACT
<p><b>OBJECTIVE</b>To construct cyclin D2 (CCND2) short hairpin RNA ( shRNA) plasmid for repressing the expression of CCND2 in human myeloma cell line LP-1,and to detect its effect on the proliferation and apoptosis of LP-1 cell.</p><p><b>METHODS</b>A CCND2 shRNA model was constructed and cloned into plasmid pGensil-2, then the plasmid was transfected into LP-1 cell in vitro. The CCND2 expression cell proliferation, cell cycle and cell apoptosis of the transfected LP-1 cells were studied by RT-PCR, trypanosome staining, flow cytometry and annexin V assay.</p><p><b>RESULTS</b>The transfection efficiency of LP-1 cell was 34. 2%. In the transfected LP-1 cell CCND2 mRNA expression was reduced significantly, the cell growth was inhibited significantly and the cell cycle was partly arrested in G, phase. The apoptosis rate of the transfected LP-1 cell after 72 h was (25.7+/-4.8)%.</p><p><b>CONCLUSION</b>The inhibition of CCND2 in LP-1 cells could inhibit the cell growth and induce cell apoptosis. CCND2 maybe a new therapeutic target.</p>
