Mitochondrial biogenesis is the process by which cells increase mitochondrial numbers. It was first described by John Holloszy in the 1960s, when it was discovered that physical endurance training induced higher mitochondrial content levels, leading to greater glucose uptake by muscles. Mitochondrial biogenesis is activated by numerous different signals during times of cellular stress or in response to environmental stimuli, such as aerobic exercise. WebNov 26, 2024 · Yeast strains with severe defects in ATP synthase have a relatively high propensity to produce cells with large deletions (ρ −) or total absence (ρ 0) of mitochondrial DNA, up to 100% vs 5–10% in WT ( (), see below).We therefore probed the mitotic stability of L 186 P yeast.
