Mitochondrial Biogenesis - an overview ScienceDirect …

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. WebIt is known that Duchenne dystrophy is accompanied by rearrangements in the systems responsible for mitochondrial fusion/fission, mitochondrial biogenesis, and mitophagy [25,26,27]. One can see that in the present work, the skeletal muscles of mdx mice show a decrease in the expression of the Mfn2 , Ppargc1a , Pink1 , and Parkin genes ( Figure 6 ).
