Learning from Whales: Oxygen, Ecosystems and Human Health (2021-2022)
Hypoxia occurs when tissues are deprived of an adequate oxygen supply and is a critically important concern in human clinical settings, including heart attack, stroke, surgery and cancer. In the animal kingdom, deep-diving whales appear to have adapted an exquisite tolerance for hypoxia, demonstrated by their ability to dive at depth, often for hours, while foraging. Marine mammals may hold the answer to developing new ways to protect hypoxia-sensitive species and create new clinical interventions for hypoxia as it relates to human health.
This team used genetics to identify cellular adaptations of deep-diving marine mammals and uncover candidate genes that help them cope with low oxygen conditions (i.e. hypoxia). They found heightened mitochondria levels in deep-diving marine mammals and identified differentiation in genes associated with tumor regulation, inflammation and immune response between deep and shallow-diving marine mammals.
