'Fountain of Youth' pill created by Harvard scientists reverses aging

Is eternal youth within our grasp? A team of scientists at Harvard University believes so as they edge closer to discovering the famed Fountain of Youth.

Their recent publication in the scientific journal Aging unveils the identification of six chemical concoctions capable of reversing the aging process in both human and rodent skin cells.

Meet Dr. David Sinclair

Dr. David Sinclair, a molecular biologist at Harvard Medical School, and co-author of the study, hails this as a “breakthrough”. He sees it as a step towards “affordable whole-body rejuvenation.”

Sinclair’s audacious prediction that human trials could commence within the next year got people talking, including none less than the tech titan Elon Musk, who curiously asked: “Ok, so what exactly is it?”

Understanding the “Fountain of Youth”

The Fountain of Youth is a legendary spring that reputedly restores the youth of anyone who drinks or bathes in its waters.

People have recounted tales of such a fountain across the world for thousands of years. Mention of a Fountain of Youth appear in writings by Herodotus, the Alexander romance, and the stories of Prester John.

The exact location of the mythical fountain has been described differently in various stories and legends. One of the most famous associated locales is Florida.

Tradition says that Spanish explorer Juan Ponce de León, the first recorded European to reach Florida, discovered Florida while he was searching for the Fountain of Youth. However, there is no contemporary evidence to support this claim.

In modern times, people often use the Fountain of Youth metaphorically to represent anything that has the potential to increase longevity or reverse aging. This can be anything from a scientific breakthrough, to a new skincare product, or a healthful lifestyle.

Cramming the Fountain of Youth into a Pill

The Harvard researchers used high-throughput cell-based assays to differentiate young cells from their older, non-dividing, or senescent counterparts — a characteristic of aging.

They tested thousands to millions of samples rapidly for biological activity, resulting in the identification of six chemical mixtures that “restored genome-wide transcript profiles to youthful states and reversed transcriptomic age in less than a week.”

“Miraculous” aging reversal

Testing these mixes on mice and human cells suggested a de-aging effect for all six combinations.

The effect of this four-day treatment is comparable to the total change seen after a year of a regenerative treatment described in a landmark study from 2019, which also focused on restoring epigenetic information.

Researchers evaluated age changes using rodent and human transcriptomic clocks, which predict biological age using gene expression data.

“This new discovery offers the potential to reverse aging with a single pill, with applications ranging from improving eyesight to effectively treating age-related diseases,” said Dr. Sinclair.

Word of caution: Not all are convinced

However, other biologists are skeptical of this enthusiastic claim. Matt Kaeberlein, a biogerontologist, offered cautious praise.

He noted that while the innovative screening method could lead to significant discoveries, the study is still preliminary.

Kaeberlein suggested the team should have validated at least one of the concoctions in an animal model and shown improvements in age-related health metrics or lifespan before making claims about effects on biological aging.

Dr. Charles Brenner, a metabolism researcher, raised concerns about three compounds in the study. CHIR99021 blocks glycogen formation during sleep to store energy; tranylcypromine is an antidepressant; and valproic acid treats bipolar disorder but can harm the liver.

The study didn’t mention these risks, and Brenner warned, “These are generally not safe alone or in combination.”

Brenner also criticized the study for not using single-cell sequencing to evaluate cell identity. He pointed out that researchers initially reported these cocktails in 2013, suggesting the compounds aren’t new discoveries.

“Getting these readouts on cells is not a groundbreaking study on the reversal of aging,” said Brenner.

Forever young? Not quite yet

The pursuit of eternal youth has taken a significant step forward with Harvard scientists identifying six chemical mixtures that show promise in reversing the aging process in human and rodent cells.

While Dr. David Sinclair and his team hailed this as a breakthrough towards potential whole-body rejuvenation, skepticism remains among other biologists regarding the safety and preliminary nature of the findings.

As the scientific community awaits further validation and research, the dream of a Fountain of Youth in pill form remains tantalizingly close yet still elusive.
