Cancer Res:肥胖促进卵巢癌转移机制被揭开

2015-12-09 MedSci MedSci原创

卵巢癌是一种致死性疾病,不仅检测困难,而且进展迅速。超过75%的卵巢癌患者在初次诊断时已经发生了转移,造成卵巢癌患者的5年生存率不到30%。 大量的研究显示,患者的身体质量指数(BMI)与卵巢癌患者更差的总生存期相关。超过35%的美国女性为肥胖人群,导致这部分女性的癌症风险更大。 最近,来自美国圣母大学(University of Notre Dame)




卵巢癌是一种致死性疾病,不仅检测困难,而且进展迅速。超过75%的卵巢癌患者在初次诊断时已经发生了转移,造成卵巢癌患者的5年生存率不到30%。

大量的研究显示,患者的身体质量指数(BMI)与卵巢癌患者更差的总生存期相关。超过35%的美国女性为肥胖人群,导致这部分女性的癌症风险更大。

最近,来自美国圣母大学(University of Notre Dame)及其附属Harper癌症研究所(Harper Cancer Research Institute,HCRI)的研究者评估了肥胖对卵巢转移的影响,揭示了卵巢癌和肥胖的新关系。

来自HCRI的M. Sharon Stack、Ann F. Dunne和Elizabeth Riley说道,在美国,卵巢癌是主要的导致死亡的妇科恶性肿瘤。

“卵巢癌转移的机制与众不同,容易导致腹腔很多转移灶产生,从而使手术治疗面临巨大挑战,”Stack说道。

研究者采用了结合3D细胞培养模型、组织种植和小鼠模型的实验方法对肿瘤细胞对腹腔间皮细胞的粘附情况。

“在3D组织培养模型中,我们发现含有脂质的间皮细胞,或者将间皮细胞种植在有脂肪的环境下,肿瘤细胞对间皮细胞的粘附能力更强,”Stack说道。“因为肿瘤细胞-间皮细胞间的连接是卵巢癌转移的关键步骤,这些实验结果促使我们在小鼠模型中继续对其进行研究。我们喂食小鼠高脂肪饮食,使得小鼠增肥40%,然后我们将携带荧光的卵巢癌细胞注入到小鼠中,观察卵巢癌细胞的转移到腹腔中的情况。”

“在所有的模型中,我们发现肥胖可以促进卵巢癌转移,”Stack说道。

目前研究者对肥胖对卵巢癌转移的机制知之甚少,未来还需要开展大量的工作揭示相关机制。
