...... A whole range of human muscular and neuromuscular diseases, are caused by mutations in the mitochondrial respiratory chain/oxidative phosphorylation system. The problem is that there are about 120 genes involved in this system, some that are found in the mitochondria, and thus inherited through the mother, and some that are found in the nucleus and are inherited from both the mother and...JCI table of contents: 1 September, 2004

This is done by inducing cells to stop any biochemical pathways that use energy and by turning on processes that take up glucose and free fatty acids from their surroundings in order to rebuild their ATP reservoir. The main protein involved in...JCI table of contents, 2 August, 2004
