Effect of Bortezomib on Proliferation, Apoptosis and SHP-2 Gene Expression of Lymphoma Cells / 中国实验血液学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effects of Bortezomib on proliferation, apoptosis and SHP-2 gene expression of lymphoma Jurkat cells and Raji cells.</p><p><b>METHODS</b>Methylthiazoly tetrazolium assay (MTT) was used to observe the proliferation of Jurkat cells and Raji cells treated with bortezomib in different doses. Cell apoptosis was detected by morphological examination and flow cytometry. The level of SHP-2 mRNA expression before and after the treatment with bortezomib was measured by RT-PCR.</p><p><b>RESULTS</b>Bortezomib could inhibit the proliferation of Jurkat and Raji cells and induce their apoptosis with time-and dose-dependent manner. After treatment with 5-100 nmol/L bortezomib, the expression of SHP-2 in Jurkat cells and Raji cells was upregulated.</p><p><b>CONCLUSION</b>Bortezomib can inhibit the proliferation and induc the apoptosis of Jurkat and Raji cells obviously, upregulate the expression of SHP-2 mRNA, suggesting that the SHP-2 may participate in regulation of bortezomib induced apoptosis of Jurkat cells and Raji cells.</p>
