Genome evolution. Gene fusion versus gene fission.

Fusion and fission: interlinked processes critical for mitochondrial health.

Mitochondria are dynamic organelles that continually undergo fusion and fission. These opposing processes work in concert to maintain the shape, size, and number of mitochondria and their physiological function. Some of the major molecules mediating mitochondrial fusion and fission in mammals have been discovered, but the underlying molecular mechanisms are only partially unraveled. In particul...

Fission–fusion populations

obese. Applying an understanding of nutritional and evolutionary theory to the modern human nutritional dilemma has turned out to be very enlightening indeed. Who have been your most important mentors? Two people have had the greatest impact on my career. The fi rst was the late Reg Chapman as my PhD supervisor. Reg and his wife Liz Bernays were inspiring, selfl ess and incredibly tolerant. I c...

Mitochondrial fission and fusion.

Mitochondria are highly dynamic cellular organelles, with the ability to change size, shape and position over the course of a few seconds. Many of these changes are related to the ability of mitochondria to undergo the highly co-ordinated processes of fission (division of a single organelle into two or more independent structures) or fusion (the opposing reaction). These actions occur simultane...
