ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effects on chemotherapeutic sensitization of the PI3K inhibitor LY294002 in diffuse large B cell Lymphoma (DLBCL) cell lines ly1, ly8, ly10.</p><p><b>METHODS</b>The three cell lines were treated with LY294002, or doxorubicin alone or combined or sequentially respectively. Western blotting was used to detect the level of phospho-AKT after the treatment. Flow cytometry combined with annexin V-FITC assay and Brdu incorporation assay were used to analyze the alterations of cell cycle, proliferation, and apoptosis, respectively.</p><p><b>RESULTS</b>LY294002 decreased the level of phospha-AKT efficiently in the three DLBCL cell lines. The ratio of S phase cells was significantly decreased (P < 0.05). Sequential use of LY294002 and doxorubicin increased the ratio of apoptosis and there was significant difference between the sequential group and the other four groups (P < 0.05) at 24, 48, 72(ly1), 48, 72 (ly8) or 24 h (ly10).</p><p><b>CONCLUSION</b>LY294002 can sensitize doxorubicin-induced apoptosis and may be a potential molecular therapeutic agent targeted at AKT signaling pathway in DLBCL.</p>
