Cell-free RNA(cf RNA) allows assessment of health, status, and phenotype of a variety of human organs and is a potential biomarker to non-invasively diagnose numerous diseases. Nevertheless, there is a lack of highly efficient and bias-free cf RNA isolation technologies due to the low abundance and instability of cf ***, we developed a reproducible and high-efficiency isolation technology for different types of cell-free nucleic acids(containing cf RNA and viral RNA) in serum/plasma based on the inclusion of nucleic acids by metal-organic framework(MOF) materials, which greatly improved the isolation efficiency and was able to preserve RNA integrity compared with the most widely used research kit method. Importantly, the quality of cf RNA extracted by the MOF method is about 10-fold that of the kit method, and the MOF method isolates more than three times as many different RNA types as the kit method. The whole transcriptome mapping characteristics of cf RNA in serum from patients with liver cancer was described and a cf RNA signature with six cf RNAs was identified to diagnose liver cancer with high diagnostic efficiency(area under curve = 0.905 in the independent validation cohort) using this MOF method. Thus, this new MOF isolation technique will advance the field of liquid biopsy, with the potential to diagnose liver cancer.
