技術簡介
本揭露提供一種用於癌症檢測之循環生物標記的鑑別系統、用於癌症檢測之循環生物標記的開發方法、癌症檢測方法及試劑盒,所述開發方法包括以下步驟。識別正常組織檢體與腫瘤組織檢體中之複數個基因的表現量,且挑選腫瘤組織檢體中具高表現量的基因。之後,使用單一組織高表現基因及組織群高表現基因計算人體各組織對於血漿外泌體貢獻的權重。接下來,以重疊指數比對健康人與罹癌患者之血漿外泌體基因的表現量,並從中挑選適用以血漿外泌體檢測及評估的循環生物標記及其組合。
Abstract
An identification system of circulating biomarkers for cancer detection, a development method of circulating biomarkers for cancer detection, a cancer detection method and a kit are provided, and the development method includes the following steps. Expression levels of multiple genes in normal tissue samples and tumor tissue samples are identified, and genes with high expression levels in tumor tissue samples are selected. Afterwards, a weight of each tissue’s contribution to plasma exosomes is calculated using Tissue-specific genes and Group-enriched genes. Next, expression levels of plasma exosome genes of healthy people and cancer patients are compared by the overlapping index, and circulating biomarkers and combinations thereof suitable for detection and evaluation of plasma exosomes are selected.
