Chem Res Toxicol:啤酒花提取物可降低乳腺癌的发生风险

2016-06-24 MedSci MedSci原创

啤酒花植物花头,可用于酿造啤酒风味并保持啤酒稳定,也可用作膳食补充剂来治疗更年期症状及其他疾病。已知激素替代疗法可增加乳腺癌的发病风险,因此一些女性将啤酒花提取物作为一种替代疗法,但是,啤酒花提取物对癌症的影响尚未清楚。日前,来自芝加哥伊利诺伊大学(UIC)研究中心的一项新的研究表明,啤酒花提取物与乳腺癌风险降低之间或存在关联,该研究成果已发表于Chemical Research in Toxic

啤酒花植物花头,可用于酿造啤酒风味并保持啤酒稳定,也可用作膳食补充剂来治疗更年期症状及其他疾病。已知激素替代疗法可增加乳腺癌的发病风险,因此一些女性将啤酒花提取物作为一种替代疗法,但是,啤酒花提取物对癌症的影响尚未清楚。日前,来自芝加哥伊利诺伊大学(UIC)研究中心的一项新的研究表明,啤酒花提取物与乳腺癌风险降低之间或存在关联,该研究成果已发表于Chemical Research in Toxicology。

一直以来认为长期暴露于雌激素是乳腺癌发生的一个危险因素,尤其是对于更年期女性。为了缓解潮热和其他更年期症状,有些女性采用激素替代疗法(HRT)来替代缺少的激素,包括雌激素。

然而,已知HRT与乳腺癌及心脏病发生风险的增加有关,所以有些女性开始寻求其他的天然替代物,如啤酒花提取物,它含有植物雌激素或植物性雌激素。但是,啤酒花提取物对癌症风险的何影响尚未清楚。

研究人员指出实验室初步研究表明,啤酒花中的一些活性物质或具有保护作用,因此他们决定行进一步的研究。

啤酒花提取物和6-PN增强细胞解毒途径

研究人员测试了富含啤酒花提取物对雌激素代谢过程的影响,而雌激素代谢过程与乳腺癌的发生有关。

研究人员测试了两种不同的乳腺细胞系。结果发现,其中一种啤酒花物质,特别是6-prenylnaringenin(6-PN),能够增强细胞的解毒途径。既往研究已证实这一途径与乳腺癌的风险降低有关。

作者指出,“结果表明,啤酒花提取物与6-PN可优先诱导两种细胞系的2-羟基化途径。”
最后,他们总结道,该研究发现表明了6-PN或具有抗癌性,但仍需进一步的研究加以证实。

在美国女性中,乳腺癌的发病率仅次于皮肤癌,不过部分男性也可发生乳腺癌。据估计,2012年,美国约有224147名女性和2125名男性诊断为乳腺癌,最终有41150名女性和405名男性死于该疾病。
