The US researchers, whose study is published in Nature Genetics, analysed samples of tumours and blood samples from cancer patients to find markers for different organs in the blood.
美国研究人员分析了癌症患者的肿瘤样本和血液样本,从而找出血液中不同器官的标记。他们将研究成果发表在了《自然遗传学》杂志上。
They created a DNA database for the liver, intestine, colon, lung, brain, kidney, pancreas, spleen, stomach and blood.
研究人员创造了一个肝脏、肠道、结肠、肺、脑、肾、胰腺、脾、胃以及血液的DNA数据库。
Now the bioengineers know the normal cells, killed off when tumour cells compete with them for space and nutrients, also release a DNA signature, called CpG methylation haplotypes.
现在,这些生物工程师们发现在与肿瘤细胞争夺空间及营养物质时被杀死的正常细胞也释放一种DNA信号,叫做CpG甲基化单体。
They were able to test which organ they came from by checking their diagnoses back against the cancer patients.
他们可以通过对比癌症患者之前的诊断检测出这些细胞来自哪个器官。
The researchers screened blood samples from individuals with and without tumours, looking for signals of the cancer markers and the tissue-specific methylation patterns.
研究人员通过检测患有癌症和健康的个体的血液样本,寻找肿瘤标志物的信号以及组织特异的甲基化模式。
