Liver regeneration: you can do without stem cells

The data obtained in experiments on mice indicate the existence of molecular mechanisms capable of triggering the process of liver regeneration due to the division of its specialized, rather than stem cells.

Better than endless horror

A resident of the USA decided to remove her colon: four of her relatives died of intestinal cancer within a few years, and gene analysis confirmed the presence of a mutation in Lynn herself, which dramatically increases her chances of getting sick.

Lung cancer was cured with a "spoiled" oncogene

After a year, during which the mice received 8 cycles of therapy (4 weeks of activation of the inhibitor gene, then 4 weeks of "rest"), almost all experimental animals were completely free of cancer.

Death in nature has no purpose – only consequences

Today, an active search is underway for a hypothetical "genetic program of death" in humans and ways to cancel it, but at this stage it is difficult to speculate what achievements we will achieve in this area.

How to rejuvenate an old brain

Blocking the genetic switch prevents the maturation of the brain and even allows the adult brain to return to the plastic state characteristic of a young age.
