Do humans have a hidden 'hibernation superpower' in their genes?

Scientists have just discovered a cluster of genes that control hibernation in mammals, and humans also carry this set of genes.

In many mammals, hibernation is a special biological state that helps the body slow down its metabolism, conserve energy, and withstand harsh environmental conditions. According to genetics professor Christopher Gregg of the University of Utah, it is the genes that regulate this process that create "a series of biological superpowers" such as resistance to brain damage and selective insulin resistance.

When animals wake up from hibernation, blood rushes to the brain, which would normally cause a stroke in humans. But thanks to a special protective mechanism, their brains are not damaged.

Additionally, some animals such as ground squirrels can develop insulin resistance to store fat before hibernation, but then this ability naturally disappears.

Surprisingly, humans also possess similar gene segments, and scientists believe that we can completely exploit these mechanisms for medical purposes.

Breakthrough from lab mice

In a study published in the journal Science on July 31, a research team at the University of Utah (USA) identified key factors located near the FTO gene cluster, which is related to metabolic control, body mass and obesity risk in humans.

Although mice don’t hibernate, they can enter a state of “torpor,” a temporary sleepiness when they’re hungry, which is good enough to study similar genetic mechanisms. Using the gene-editing tool CRISPR, scientists “disabled” five non-coding regulatory DNA sequences (CREs) in mice and observed:

Deletion of a CRE segment named E1 caused female mice to gain significant weight when fed a high-fat diet.

Deletion of the E3 fragment changes the way mice forage in experimental environments.

In other words, tweaking just a few small stretches of DNA was enough to change the behavior, metabolism, and physiological responses of mice. This opens up the possibility of modifying human metabolism through similar gene clusters.

Is it possible to induce "hibernation" in humans?

Scientists warn that applying similar genetic changes to humans is not simple.

"Humans are not able to enter a state of torpor due to fasting like mice, so it is difficult to simulate the same mechanism," noted professor Joanna Kelley (University of California, Santa Cruz).

Additionally, while torpor in mice is triggered by starvation, true hibernation in species like bears is driven by circadian rhythms and hormones.

Still, the research lays the groundwork for new treatments. In the long term, Gregg hopes to develop drugs that modulate the human “hibernation gene hub,” providing neuroprotection and metabolic stability without actually putting patients into hibernation.

Prospects in future medicine

The discovery of genes related to hibernation is not only a major step forward in biology but also opens up enormous potential for applications in modern medicine.

If we can understand how these genes work, especially how they help animals regulate metabolism, conserve energy, and protect the body during hibernation, it is entirely possible that they could be used to develop new treatments for humans.

Thanks to the controlled insulin resistance mechanism of hibernating animals, scientists hope to find more effective ways to deal with obesity and type 2 diabetes.

The fact that animals can "survive" a blood rush to the brain without damage has important implications for developing methods to prevent neurological damage, such as after a stroke.

In addition, it can also be applied in space medicine and intensive care with the ability to put people into a low metabolic state (similar to hibernation) to prolong life in cases of severe trauma, or during long journeys in space.

Although there are still many challenges ahead, this research has opened up a completely new direction, where humans can exploit their own genes to serve their health and life.
