“Co-treatment with ATO plus quercetin caused mitochondrial transmembrane potential dissipation, stimulated the mitochondrial apoptotic pathway, as indicated by cytochrome c and Omi/Htra2 release, XIAP and Bcl-X(L) down-regulation, and Bax activation, and caused caspase-8/Bid activation.”
“The present work demonstrates that the flavonoids quercetin and chrysin cooperate with ATO to induce apoptosis in U937 promonocytes and other human leukemia cell lines (THP-1, HL-60).”
