Understanding how living at high altitudes changes the body and what it means for heart and brain health

Official title: Physiological plasticity and the mechanisms of adaptation to hypoxia: exploiting natural variation in wild deer mice

Funded at University of Denver (Colorado Seminary) · NIH-11332588 · Data updated 2026-11-12

This NIH grant studies how living in low-oxygen conditions affects breathing, blood flow, and heart health by using wild deer mice to uncover natural biological tricks that help cope with hypoxia.

Who could benefit from this research

Could help

Patients with chronic mountain sickness, high-altitude illness, congenital or acquired heart or brain vascular disorders, or conditions worsened by hypoxia could indirectly benefit from advances in understanding hypoxia tolerance.

Less likely to help

Individuals without conditions related to hypoxia or high-altitude exposure may not see direct personal benefit.

What this research studies

Researchers study wild deer mice that live at very high elevations to uncover the genetic and molecular ways their bodies adapt to low oxygen. They aim to map how these adaptations influence oxygen homeostasis and remodeling of blood vessels, which can affect the heart and brain in people living with chronic hypoxia. The work combines field observations with laboratory analyses to identify conserved pathways that could inform treatments or prevention strategies for high-altitude illness and related cardiovascular and cerebrovascular conditions. This project focuses on evolutionary biology with potential translational implications for human health under hypoxic stress.

Why it matters

Potential benefit: Findings could lead to new approaches to prevent or treat heart, brain, and pregnancy complications linked to low oxygen levels.

How similar studies have gone: Previous work in animal models and human studies supports the idea that adaptive responses to hypoxia involve vascular and blood flow changes, suggesting potential for translation.
