Nature:发布!人类癌症细胞的转移图谱 

2020-12-10 haibei MedSci原创

研究人员创建了第一代转移图(MetMap),揭示了器官特异性的转移模式,使这些模式与临床和基因组特征相关联。

人类癌症细胞系一直是癌症研究的驱动力,帮助研究人员发现多种致癌机制和治疗靶点。然而,细胞系的大规模表征被限制在基本的读数中,如在细胞培养系统中的生存能力。目前,更复杂的表型,如肿瘤细胞在体内的行为,一直无法被规模化表征。相比之下,大多数研究的肿瘤转移只依靠了少数实验模型,因而很难将结论外推到遗传多样性的人类肿瘤中去。

最近,研究人员在Nature杂志发文,报导其引入了一种体内条形码策略,能够大规模地确定小鼠异种移植物中人类癌症细胞系的转移潜力,并将其应用于500个细胞系和跨越21种类型的实体瘤中,验证了该方法的稳健性,可扩展性和可重复性。

研究人员创建了第一代转移图(MetMap),揭示了器官特异性的转移模式,使这些模式与临床和基因组特征相关联。研究人员通过研究能够转移到脑部的乳腺癌的分子基础来证明MetMap的效用,脑转移的乳腺癌是致死的主要原因之一。

能够转移到大脑的乳腺癌显示出脂质代谢改变的证据。这些细胞中脂质代谢的扰动抑制了脑转移的发展,也提出了一种防治疾病的治疗策略,并证明了MetMap作为支持转移研究的资源的效用。

转移是导致大多数癌症相关死亡的原因。虽然原发性肿瘤内的基因组异质性与复发有关,但至今为止,我们尚未全面评估未治疗的转移灶之间的异质性。

肿瘤转移的器官亲和性:重新梳理种子-土壤假说

肿瘤转移是癌症发展过程中最致命的阶段并且导致了癌症引起的绝大部分死亡病例。通过临床观察,人们发现了肿瘤转移有器官特异性,称为“器官亲和性(organotropism)”。即不同类型的肿瘤倾向于转移到不同的器官,例如前列腺癌主要转移到骨,葡萄膜黑色素瘤通常转移到肝脏。同一种癌症的不同亚型也会有不同的亲器官性,例如腔上皮型乳腺癌很大一部分转移到骨,然而三阴型乳腺癌更容易转移到内脏器官。因此,阐明肿瘤转
