Abstract excerpt
Mitochondrial DNA (mtDNA) mutations are emerging as important molecular features of tumorigenesis. Liquid biopsies, involving analysis of cell-free mtDNA, enable early cancer detection but suffer from low sensitivity due to scarce analytes. Here, we developed a CRISPR/Cas12a-mediated urinary biomarker, termed CasUber, for in vivo monitoring of tumor progression and metastasis. Our results demonstrate that CasUber...
