槲皮素（ｑｕｅｒｃｅｔｉｎ）是一种天然黄酮类化合物 ,它能抑制多种癌细胞株的生长 ,对白血病的治疗具有巨大潜力 ,其抗增殖的作用机理虽有许多研究［１，２］，但对ｃ ｍｙｃ和ｃｙｃｌｉｎＤ１的影响却少有报道。本实验以ＨＬ ６０细胞为靶细胞 ,研究槲皮素对ｃ ｍｙｃ和ｃ Quercetin is a natural flavonoid that inhibits the growth of many cancer cell lines and has great potential for the treatment of leukemia. Although there are many researches on its anti-proliferative mechanism [1,2], The effects of c myc and cyclinD1 have been rarely reported. In this experiment, HL 60 cells were used as target cells to study quercetin on c myc and c
