In fact, fasting (raises glucagon) provides the greatest known boost to autophagy.įasting is actually far more beneficial than just stimulating autophagy. This increase in glucagon stimulates the process of autophagy. When we don’t eat (fast) insulin goes down and glucagon goes up. As we eat, insulin goes up and glucagon goes down. It’s like the game we played as kids – ‘opposite day’. Remember that glucagon is kind of the opposite hormone to insulin.

Nutrient deprivation is the key activator of autophagy. When mTOR is activated, it suppresses autophagy, and when dormant, it promotes it. One of the key regulators of autophagy is the kinase called mammalian target of rapamycin (mTOR). Damaged sub cellular parts and unused proteins become marked for destruction and then sent to the lysosomes to finish the job. The Nobel prize winning scientist Christian de Duve coined the term autophagy. This is done by sending it to the lysosome which is a specialized organelle containing enzymes to degrade proteins.Īutophagy was first described in 1962 when researchers noted an increase in the number of lysosomes (the part of the cell that destroys stuff) in rat liver cells after infusing glucagon. Old cell membranes, organelles and other cellular debris can be removed. That is the process of autophagy, where sub-cellular organelles are destroyed and new ones are rebuilt to replace it. Instead of killing off the entire cell (apoptosis), you only want to replace some cell parts. Sometimes, you just need to replace the battery, throw out the old one and get a new one. You don’t necessarily need to replace the entire car. The same process also happens at a sub-cellular level. Autophagy – replacing old parts of the cell You don’t have to worry about it breaking down at the worst possible time.
After a certain amount of time, you get rid of the car, whether it’s still working or not. That’s the process of apoptosis, where cells are pre-destined to die after a certain amount of time.
It is better that they be programmed to die when their useful life is done. So you get rid of it and buy a snazzy new car. Is it better to keep it around when it’s nothing but a hunk of junk? Obviously not. The car is costing you thousands of dollars every year to maintain. After a few more, it’s not looking so great. You love to ride it.īut after a few years, it starts to look kind of beat up. While this may sound kind of macabre at first, realize that this process is essential in maintaining good health. Cells, after a certain number of divisions, are programmed to die. There is a similar, better known process called apoptosis, also known as programmed cell death. It is a regulated, orderly process to degrade and recycle cellular components. Essentially, this is the body’s mechanism of getting rid of all the broken down, old cell machinery (organelles, proteins and cell membranes) when there’s no longer enough energy to sustain it. So the word literally means to eat oneself. On October 3rd, the Nobel Assembly at Karolinska Institutet has awarded the Nobel Prize in Physiology or Medicine to Yoshinori Ohsumi for his discoveries of mechanisms for autophagy.īut what is autophagy? The word derives from the Greek auto (self) and phagein (to eat).
