Recently, the research findings of the team led by CAS Academician Xiang Zhou from Wuhan University were published in the National Science Review. The team successfully developed an efficient technique for enriching trace amounts of circulating nucleic acids in blood.
Early diagnosis of diseases can significantly improve clinical treatment outcomes and survival rates. Circulating cell-free nucleic acids in blood represents a promising avenue for non-invasive early disease diagnosis.
However, the lack of efficient tools for obtaining cell-free nucleic acids has been a challenge. The team developed a blood-circulating nucleic acid enrichment technique based on MOF (metal-organic framework) materials, which exhibited higher enrichment efficiency compared to commercial reagent kits and prevented RNA degradation.
Additionally, the team applied this technique in combination with high-throughput sequencing and bioinformatics analysis to identify cell-free RNA serum biomarkers for non-invasive diagnosis of liver cancer. They constructed a detection model to identify liver cancer, which achieved a diagnostic accuracy of 90% when validated in another sample cohort, demonstrating its potential for non-invasive liver cancer diagnosis.
