25-Year Dolphin Health Study Reveals Factors Contributing to Slow and Accelerated Aging Rates in Long-Lived Mammals


SAN DIEGO, Aug. 10, 2020 /PRNewswire/ -- Epitracker Inc. today announced the results from a groundbreaking, 25-year longitudinal cohort study of bottlenose dolphins that identified factors differentiating individuals with slow and accelerated aging rates.

The study, which was published in the Proceedings of the National Academy of Sciences, highlights how biological differences between dolphins living in the same natural ocean environment and receiving routine medical examinations under the care of the United States Navy may inform new approaches to slow degradative processes associated with aging. 

Epitracker, a life sciences company applying advanced omic technologies to discover therapeutics for aging-associated diseases, leveraged archived health data on 144 dolphins receiving meticulous care throughout their lives. These health data included 44 clinically relevant measurements on 5,889 biological routine samples collected throughout dolphins' lifetimes.

"Amazingly, this work all started with the sole intent of continually improving the health and welfare of dolphins," said Stephanie Venn-Watson, D.V.M., M.P.H., co-founder and CEO of Epitracker Inc. and Seraphina Therapeutics, and the study's lead author. "The fact that our work is resulting in groundbreaking approaches to delay aging and improve health for both dolphins and humans is a dream come true."

Navy dolphins, which on average live 50 percent longer than wild dolphins, consumed a controlled and well-maintained fish diet and received ongoing health monitoring and medical care. The routine health data and 44 measures collected over time were analyzed to determine aging rates and establish aging rate-related biomarkers that could also be studied in humans.

Epitracker discovered four key biomarkers in dolphins associated with an accelerated aging rate. Two of these biomarkers, which already are used in assessing older people, decreased linearly with age: hemoglobin, used to detect anemia; and lymphocytes, used to detect immunosenescence, or weakened immunity. Importantly, while some dolphins had declines in these clinical biomarkers as they aged, including declines leading to clinical anemia and immunosenescence, others had no declines during the same aging timeframe.  

While it has long been believed that there are factors influencing why some humans and mammals age faster than others, identifying those factors requires a data set that has been difficult to develop in species closely related to humans ? one that is sufficiently large, robust, longitudinal in nature, and collected in a well-controlled population over lifetimes.

"The nature of the Navy dolphins' shared oceanic environment created a perfect setting to generate unparalleled longitudinal health data using easily measured biomarkers that identified slow and accelerated aging in dolphins," said Nicholas Schork, Ph.D., senior author and Professor at the Translational Genomics Research Institute, as well as Scientific Director for the National Institute on Aging's Longevity Consortium.

"The results from the analysis of the dolphin population are directly translatable into human biology and will now empower us to identify how aging rates vary in humans and what we might be able do to slow the rates down for all," Schork said.

This study is one of three recently published peer-reviewed scientific articles from Epitracker and its spin-out health and wellness company, Seraphina Therapeutics, demonstrating the promise of applying advanced technologies to delay aging in dolphins and humans.

In April 2020, Epitracker reported in PLOS ONE how a wild-type fish diet shifted dolphins' metabolomes and improved their health. In this study, increased dietary intake of a trace saturated fat called pentadecanoic acid (C15:0) predicted reversal of low hemoglobin, a key biomarker of accelerated aging rates. Surprisingly, anemia was alleviated in all dolphins placed on a C15:0-rich diet.

Subsequent laboratory studies led by Epitracker and Seraphina and recently published in Scientific Reports, showed repeated, broad health benefits of C15:0 related to healthy aging, including attenuated anemia and fibrosis, lowered inflammation and cholesterol, and improved cellular stability and mitochondrial function. These studies and a growing body of global evidence support that C15:0 is the first essential fatty acid to be discovered in 90 years.

"Our discovery of slow and accelerated aging dolphins is now enabling us to compare thousands of small molecules in the archived serum of individuals with and without aging-related conditions and help find which molecules have the greatest promise of protecting the health of aging mammals," Venn-Watson said.

Seraphina Therapeutics is currently advancing C15:0 as a once daily dietary supplement, food fortifier and nutritional intervention to protect against aging-associated breakdown and as a potential treatment of C15:0 deficiency disorders in humans. Seraphina aims to have C15:0 available for purchase as a supplement during Fall 2020 and as a food ingredient in January 2021.

While developing C15:0 supplements for Navy dolphins, Epitracker is also working cooperatively with the U.S. Navy to study additional serum metabolites that may help prevent and treat chronic aging-associated conditions present in both dolphins and humans, including pulmonary, hepatic, and neurogenerative diseases, including Alzheimer's disease.
