日本科学家从洋葱中分离出可以对抗卵巢癌的天然成分

日本熊本大学的研究人员最近发现从洋葱中分离得到的一种天然化合物——ONA(洋葱素A)对卵巢癌有一些抗癌特性。该研究在体内和体外实验中研究了ONA对上皮卵巢癌(EOC)临床前模型的作用,参与该研究的研究人员曾经发现ONA能够抑制宿主骨髓细胞的促肿瘤活性。根据2014年世界卫生组织对癌症医学的回顾,上皮卵巢癌是最常见的卵巢癌类型,病人的五年存活率大约为40%。80%的病人在最初接受化疗之后出现复发,因

日本熊本大学的研究人员最近发现从洋葱中分离得到的一种天然化合物——ONA(洋葱素A)对卵巢癌有一些抗癌特性。该研究在体内和体外实验中研究了ONA对上皮卵巢癌(EOC)临床前模型的作用,参与该研究的研究人员曾经发现ONA能够抑制宿主骨髓细胞的促肿瘤活性。

根据2014年世界卫生组织对癌症医学的回顾,上皮卵巢癌是最常见的卵巢癌类型,病人的五年存活率大约为40%。80%的病人在最初接受化疗之后出现复发,因此需要更加有效的治疗方法。

熊本大学的研究人员发现ONA对上皮卵巢癌有一些作用。体外实验表明,加入ONA能够抑制上皮卵巢癌细胞的生长,研究人员认为这种作用主要是由于ONA影响了一个叫做STAT3的转录因子,STAT3能够参与M2型巨噬细胞极化和癌细胞增殖。通过使用临床前肉瘤模型进行研究发现ONA能够抑制骨髓衍生抑制细胞(MDSC)的促肿瘤功能,而MDSC与宿主淋巴细胞的抗肿瘤免疫应答受到抑制有关。ONA还能够通过加强抗癌药物的抗增殖能力促进抗癌药物发挥作用。此外,研究人员还利用卵巢癌小鼠模型研究了口服给予ONA的作用效果,发现小鼠模型的寿命得到延长,同时卵巢癌的肿瘤发育受到抑制。研究人员认为这是ONA抑制了M2型巨噬细胞的结果。

这项研究表明ONA通过干扰骨髓细胞的促肿瘤功能延缓恶性卵巢癌进展。ONA还能够抵消骨髓细胞的免疫抑制功能激活抗肿瘤免疫应答。除此之外ONA具有增强现有抗癌药物效果的潜力,并且对正常细胞几乎没有毒性作用。研究人员并没有在动物模型中观察到ONA的任何副作用。如果再继续进行更多实验,口服ONA药物将为癌症病人带来巨大获益。
