Paper

Abstract

Mitochondria, cellular powerhouses, harbor DNA (mtDNA) inherited from the mothers. MtDNA mutations can cause diseases, yet whether they increase with age in human germline cells-oocytes-remains understudied. Here, using highly accurate duplex sequencing of full-length mtDNA, we detected

Research summary

The paper investigates mitochondrial DNA mutations in human oocytes and their relationship with age, which is pertinent to understanding the biological mechanisms of aging. While it provides solid research on the frequency-dependent selection of mtDNA mutations, it does not directly address root causes of aging or lifespan extension. Therefore, it represents a solid contribution but with limited impact on the broader field of longevity research.
