Type 2 diabetes increases oocyte mtDNA mutations which are eliminated in the offspring by bottleneck effect

Abstract excerpt

BACKGROUND: Diabetes induces many complications including reduced fertility and low oocyte quality, but whether it causes increased mtDNA mutations is unknown. METHODS: We generated a T2D mouse model by using high-fat-diet (HFD) and Streptozotocin (STZ) injection. We examined mtDNA mutations in oocytes of diabetic mice by high-throughput sequencing techniques. RESULTS: T2D mice showed glucose intolerance, insulin...
