Long-lived proteins are the key to understanding the mechanisms of aging

Identification of long–lived proteins, which may be the weakest link of the aging proteome – a set of proteins expressed by the genome under given environmental conditions - will help to understand the molecular basis of aging.

Leptin instead of insulin?

Swiss researchers conducted a series of experiments on rodents deprived of the ability to synthesize insulin, which were injected with leptin, a hormone that regulates energy metabolism and appetite. Thanks to leptin, all animals perfectly tolerated the state of insulin deficiency.

How mitochondria age

In a young cell, pairs of protein complexes of ATP synthase are located close to each other and, due to this, bend the mitochondrial membrane, forming folds. Over time, there are fewer such pairs, and instead of a complex structure, the membrane turns into a relatively smooth two-layer bubble.
