RGS14 – "The Homer Simpson gene"

If the RGS14 gene only slows down the brain, then why does it exist in both mice and humans? Won't genetic engineering help in the future to get rid of this brake, giving the opportunity, for example, to memorize the text by heart after the first reading?

Cancer cells survive by self-eating

As previously thought, autophagy – the process of "self–digestion" of cells - plays an important role in protecting the body from the development of cancer, but sometimes cancer cells use autophagy to survive in conditions of lack of resources.

Allergy to cancer

Scientists have deduced an amazing pattern: allergy sufferers rarely join the ranks of cancer patients. Is it a simple coincidence, or do the two ailments have much more in common than was commonly believed?

A means to prolong life: only three amino acids

The life expectancy of mice taking the essential amino acids leucine, isoleucine and valine was 12% longer than the average. Such an addition to the diet can have a positive effect on people's life expectancy.

Telomeres, histones and aging. And maybe rejuvenation…

The discovery of the connection between the shortening of telomeres and a decrease in the number of histones in the nucleus of cells as they age can be used to develop new methods of rejuvenation of an aging organism.

The death switch?

According to the researchers, the results of their work can lead to the creation of drugs that protect human organs from apoptosis – cellular "suicide".

The choice between life and death: apoptosis or autophagy?

Under stress, the cell can end its life by apoptosis or survive with the help of partial self–eating - autophagy. Scientists from the University of Pittsburgh have found a key protein for autophagy and a chain of intracellular interactions associated with it.
