  Wine Antioxidant Polyphenols Inhibit the Proliferation of Human Prostate Cancer Cell Lines

  摘要：

  The effect of different wine antioxidant polyphenols (catechin, epicatechin, quercetin, and resveratrol) on the growth of three prostate cancer cell lines (LNCaP, PC3, and DU145) was investigated A dose- and time-dependent inhibition of cell growth by polyphenols was found at nanomolar concentrations. The proliferation of LNCaP and PC3 cells was preferentially inhibited by flavonoid's (catechin, epicatechin, and quercetin), whereas resveratrol was the most potent inhibitor of DU145 cell growth. Possible mechanisms of action were investigated. 1) The competition of polyphenols for androgen binding in LNCaP cells revealed significant interaction only in the case of high concentrations of quercetin, at least at five orders of magnitude higher than the concentrations needed for cell growth inhibition. All other phenols showed low interactions. 2) Oxygen species production after mitogen stimulation and H2O2 sensitivity of these cell lines did not correlate with the observed antiproliferative effects, ruling out such a mode of action. 3) NO production revealed two different patterns. LNCaP and DU145 cells produced high concentrations of NO, whereas PC3 cells produced low concentrations. Phorbol ester stimulation of cells did not reveal any additional effect in LNCaP and DU145 cells, whereas it enhanced the secretion of NO in PC3 cells. Polyphenols decreased NO secretion. This effect correlates with their antiproliferative action and the inhibition of inducible NO synthase. It is therefore proposed that the antiproliferative effect of polyphenols is mediated through the modulation of NO production. rn conclusion, our data show a direct inhibitory effect of low concentrations of antioxidant wine phenols on the proliferation of human prostate cancer cell fines mediated by the production of NO, further suggesting potential beneficial effects of wine and other phenol-containing foods or drinks for the control of prostate cancer cell growth.

  三萜类化合物是一组结构多样的专门代谢物，经常显示出有用的生物活性。这些化学物质是由植物中常见的前体2,3-氧化角鲨烯生物合成的。氧化角鲨烯环化酶（OSC）产生的碳骨架通常会被细胞色素P450单加氧酶（P450s）和UDP依赖性糖基转移酶修饰。这些生物合成酶有助于植物三萜的结构多样化。迄今为止，许多P450酶已被表征为三萜类氧化酶。其中，CYP716家族P450酶似乎已从多种植物家族中分离出来，似乎有助于三萜类化合物的结构多样化。许多CYP716家族P450酶已被表征为多功能三萜C-28氧化酶，可以将α-amyrin和β-amyrin分别氧化​​为广泛分布的三萜类乌索酸和齐墩果酸。番茄（Solanum lycopersicum）是世界上最重要的茄科作物之一。然而，关于其三萜生物合成的信息知之甚少。为了解番茄中三萜类生物合成的机理，我们集中研究了CYP716家族酶作为三萜类氧化酶的功能。我们从
