以往的研究表明，槲皮素可抑制多种肿瘤细胞的生长及加强某些抗癌药物的抗癌细胞生长作用［１］，并可抑制癌细胞ＤＮＡ的生物合成［２］。因而，槲皮素被认为是颇具应用前景的抗癌药物或抗癌辅助药物。然而，槲皮素抗癌细胞增殖的机理尚未阐明。本文研究了槲皮素对培养的... Previous studies have shown that quercetin can inhibit the growth of many kinds of tumor cells and strengthen the anti-cancer cell growth effect of certain anti-cancer drugs [1], and can inhibit the DNA biosynthesis of cancer cells [2]. Therefore, quercetin is considered to be a promising anti-cancer drug or anti-cancer drug. However, the mechanism of quercetin anti-cancer cell proliferation has not yet been elucidated. This article studies the quercetin on cultured...
