RESUMO
<p><b>OBJECTIVE</b>To investigate the effects of quercetin on cell morphology and VEGF expression of acute myeloblastic leukemia cells NB4 in vitro.</p><p><b>METHODS</b>The cytomorphology of NB4 cells was assessed by Wright-stain, apoptosis rate by apoptotic marker Annexin V, and VEGF secretion level by ELISA.</p><p><b>RESULTS</b>Typical apoptosis was found in NB4 cells after treatment with quercetin. Apoptotic marker Annexin V analysis showed that the apoptotic rate of NB4 cells was increased after treatment with quercetin. The secretion of VEGF of NB4 cells was significantly decreased after treatment with quercetin.</p><p><b>CONCLUSION</b>Quercetin can induce apoptosis and inhibit secretion of VEGF in NB4 leukemia cells.</p>
