Cancer Med Sci:我伙呆!吃咖喱也能治肿瘤!?

2015-04-24 Zhang JL译 MedSci原创

人乳头瘤病毒(HPV)是一种属于乳多空病毒科的乳头瘤空泡病毒A属,是球形DNA病毒,能引起人体皮肤黏膜的鳞状上皮增殖。表现为寻常疣、生殖器疣(尖锐湿疣)等症状。 随着性病中尖锐湿疣的发病率急速上升和宫颈癌、肛门癌、口腔癌等的增多,人乳头瘤病毒(HPV)感染越来越引起人们的关注。最新研究发现,咖喱香料中的一种抗氧化剂——姜黄素,可以减缓或抑制HPV病毒的活性,而后者则是导致多数口腔癌和宫颈癌的罪魁祸

人乳头瘤病毒(HPV)是一种属于乳多空病毒科的乳头瘤空泡病毒A属,是球形DNA病毒,能引起人体皮肤黏膜的鳞状上皮增殖。表现为寻常疣、生殖器疣(尖锐湿疣)等症状。 随着性病中尖锐湿疣的发病率急速上升和宫颈癌、肛门癌、口腔癌等的增多,人乳头瘤病毒(HPV)感染越来越引起人们的关注。

最新研究发现,咖喱香料中的一种抗氧化剂——姜黄素,可以减缓或抑制HPV病毒的活性,而后者则是导致多数口腔癌和宫颈癌的罪魁祸首。

姜黄素是从姜科、天南星科中的一些植物的根茎中提取的一种化学成分,其中,姜黄约含3%~6%,是植物界很稀少的具有二酮的色素,为二酮类化合物。姜黄素为橙黄色结晶粉末,味稍苦。不溶于水。在食品生产中主要用于肠类制品、罐头、酱卤制品等产品的着色。医学研究表明,姜黄素具有降血脂、抗肿瘤、抗炎、利胆、抗氧化等作用。

近年的研究不仅证明了姜黄的传统作用,而且还揭示出一些新的药理作用,如抗炎、抗氧化、清除氧自由基、抗人类免疫缺陷病毒、保护肝脏和肾脏、抗纤维化以及防癌抗癌等作用,可能与其抑制核因子-κB和激活蛋白-1等转录因子的激活及表达有关,而且无明显的毒副作用。

HPV是一种促进宫颈癌和口腔癌发展的病毒,目前并没有治愈的方法,而姜黄素则可能为未来HPV的控制提供新的手段。

“姜黄素具有抗病毒和抗癌特性,” 美国亚特兰大埃默里大学的Alok Mishra博士说,“根据我们的新发现,我们可以说姜黄素是有利于口腔健康的。”

早在2005年,Mishra博士所在的研究小组已经率先指出姜黄素对人乳头状瘤病毒和宫颈癌细胞具有一定影响。姜黄素的抗氧化效应能够延缓HPV的表达,提示其可以控制HPV的感染程度。

“由于HPV相关的口腔癌病例在逐渐上升,因此我们在口腔癌中测试了相同的假设。” Mishra博士说,“由此我们得到了一些很有趣的发现。”

该项研究结果表明,姜黄素下调感染HPV的口腔癌细胞中HPV的表达,而这一现象是通过下调细胞转录因子AP-1和NF-kB的水平达到的。这些发现提示姜黄素可能在未来癌症控制的新治疗方法中发挥重要的作用。

尽管Mishra博士尚不能定论姜黄的在作为日常饭桌上一员对疾病的疗效,但他认为食用姜黄素和其他抗氧化剂对健康应该是有益的,尤其是对于HPV相关的口腔癌症。
