Quercetin and Green tea induces apoptosis of leukemic cells. NOD/SCID mice with HL60 tumors were treated or not with quercetin (120 mg/kg), once every 4 days or green tea (100 mg/kg), every day. After 3 weeks, tumors were harvested and relative levels of protein in tumor lysates were determined by Western blotting (A,B) BCL-2; (C,D) BCL-XL; (E,F) BAX; (G) -MCL-1; (H) -cytocrome c; (I) -p-JNK. (J,K) IHC analysis of cleaved caspase-3 in tumor sections and the percentage of caspase 3 positive nuclei of cells per field; four fields per tumor section. Counts were made using x40 objective connected to a light microscope (Olympus CBA; Olympus America). Values are means ± SD (mean of 6 mice/group); *P < 0.05.
