Why does the Greenland shark live longer?

Great White Shark - The Greenland shark, considered the longest-lived vertebrate known with an estimated lifespan of almost 400 years, possesses genetic characteristics that could explain its extraordinary resistance to aging and disease.

This emerges from a study published in the journal Proceedings of the National Academy of Sciences (PNAS) by Kaiqiao Yang, Kazuya Nishiwaki, Hideaki Mizobata and Shigeharu Kinoshita of the University of Tokyo, together with an international group of researchers.

The Greenland Shark Genome

The researchers have carried out the first complete chromosomal-level genomic assembly of the Greenland shark, a species adapted to the deep, cold environments of the Arctic and characterized by an extremely slow metabolism. The reconstructed genome measures approximately 5.9 gigabases, with a high level of genetic completeness of 96.7 percent.

Biological Mechanisms of Longevity

The analyses highlighted several biological mechanisms associated with extreme longevity, including strengthening of immune defenses, resistance to tumors, and particularly efficient DNA repair systems.

The Role of Histone H1.0

The researchers also identified specific amino acid modifications in the histone protein H1.0, involved in chromatin stability, which could contribute to protecting genetic material from accumulated molecular damage over centuries.

Protection from Cellular Degradation

According to the authors, these characteristics could help the Greenland shark overcome the normal biological limits of lifespan. “The amino acid substitutions observed in the globular domain of histone H1.0 could improve chromatin stability,” explain the researchers, indicating a possible mechanism of protection against age-related cellular degradation.

Longevity and Ferroptosis

The study also suggests a possible link between longevity and ferroptosis, a particular form of cell death regulated by iron and oxidative processes. The distinctive genetic repertoire of the species, the researchers observe, provides a foundation for future hypotheses on the role of ferroptosis in aging processes.

Evolution and Populations

In addition to aspects related to the biology of longevity, the work also reconstructs the historical dynamics of Greenland shark populations and the closely related species *Somniosus pacificus*, offering new information on the evolution of cartilaginous sharks.

A Resource for Future Research

According to the authors, the availability of this genome represents an important resource for evolutionary studies as well as research into the genetic mechanisms of aging. “These genomic analyses offer new perspectives on the molecular basis of the Greenland shark’s exceptional longevity,” the researchers conclude, emphasizing how the results can contribute to the development of future research on human aging and age-related diseases.
