Detection methods for mitochondrial DNA heteroplasmy and their potential single-cell applications in cancer.

Abstract excerpt

Mitochondrial DNA (mtDNA) is crucial for cellular metabolism, oxidative stress responses, and genomic stability, with mutations linked to cancer progression and therapeutic resistance. Mitochondrial heteroplasmy, the coexistence of wild-type and mutant mtDNA within a cell or across populations, plays a key role in mitochondrial dysfunction, tumor heterogeneity, and disease pathogenesis. Advances in single-cell...
