Scientists have made a remarkable breakthrough in the quest for immortality! A group of researchers at the University of California San Diego have engineered a solution that could stop the aging process of our cells, opening the door to a future where humans can live for hundreds of years.
A Step Toward Immortality?
For years, scientists have been studying the aging process, looking for ways to extend human life.
Now, a team of UC San Diego researchers has taken a major step forward in this endeavor. Using synthetic biology, they've found a way to genetically rewire the circuit that controls cell aging, effectively stalling the aging process.
According to the team, the gene regulatory circuits in cells are like the circuits in our home electric systems that control our devices. They are responsible for many physiological functions, including aging.
The researchers found that cells do not necessarily age the same way, depending on the central gene regulatory circuit controlling them. Using a "smart aging process," the team extended cellular longevity by cycling deterioration from one aging mechanism to another.
To accomplish this, the team rewired the circuit that controls cell aging, creating a negative feedback loop that stalls the aging process.
The rewired circuit acts as a gene oscillator, resembling a clock-like mechanism, that stimulates the cell to alternate between two negative "aged" states at regular intervals, preventing the cell from getting trapped in either state and decelerating its degeneration.
Through the use of computer simulations, the scientists were able to devise and experiment with concepts before making adjustments to the circuit in the cell, thereby conserving time and resources.
This is the pioneering instance in which computer-assisted synthetic biology and engineering principles were employed to systematically overhaul gene circuits and restructure the aging process to boost lifespan.
The team studied yeast cells to learn about how human cells age. They watched the cells grow old using special equipment.
They changed some of the yeast cells using a synthetic device and found that those cells lived 82% longer than normal cells. This is the longest lifespan increase ever seen in yeast cells when changing their genes.
Proof-of-concept Example
"Our work represents a proof-of-concept example, demonstrating the successful application of synthetic biology to reprogram the cellular aging process and may lay the foundation for designing synthetic gene circuits to effectively promote longevity in more complex organisms," the authors wrote.
The team's research has the potential to revolutionize scientific approaches to age delay. It provides evidence that slowing the ticks of the aging clock is possible by actively preventing cells from committing to a pre-destined path of decline and death. Clock-like gene oscillators could be a universal system to achieve that.
The researchers are now expanding their research to the aging of diverse human cell types, including stem cells and neurons. This discovery is a significant step forward in the quest for immortality, but there is still much work to be done before it becomes a reality.
Nevertheless, this breakthrough is sure to spark excitement and hope for a future where humans can live longer, healthier lives.
The findings of the study were published in the journal Science.
