Maldive Tragedy Prompts Study of Genetic Adaptation

Gregg L. Semenza, a Nobel laureate in Medicine, explained in Rome how some populations withstand low oxygen levels.

Semenza, a leading expert on cellular responses to oxygen, discussed the body’s limitations during hypoxia following recent events in the Maldives. He emphasized the critical importance of oxygen for heart and brain function, and careful ascent planning during diving to avoid dissolved gas complications.

Semenza noted certain groups demonstrate genetic adaptations to low oxygen environments. He cited pearl divers in Korea and Indonesia, and people living in high altitudes as examples of populations who can remain underwater longer due to their genetics. These adaptations allow them to better manage oxygen scarcity compared to others.

The scientist’s work clarifies how cells detect and react to oxygen availability, informing understanding of both normal physiology and disease. Further research continues to explore these mechanisms and potential therapies.
