Polymerase chain reaction, or PCR, is a laboratory technique used to make multiple copies of a segment of DNA. PCR is very precise and can be used to amplify, or copy, a specific DNA target from a ...

肾癌（Renal cancer，RC）是致死率最高的泌尿系统恶性肿瘤，30% 的患者确诊时已处于晚期。超过 50% 的肾癌患者没有明显症状，多为偶然发现。目前，肾癌检测主要依靠影像学检查，但对小尺寸肿瘤的检测灵敏度欠佳。因此，亟需一种灵敏且可靠的诊断工具，推动肾癌标准化早期检测。在本研究中，研究人员对肾癌组织和尿液样本进行全基因组甲基化测序，以探寻肾癌 DNA 甲基化标记物。研究人员利用 93 例 ...
