How high altitude affects fetal growth through blood flow signaling

Official title: Novel roles of purinergic signaling for altitude-associated fetal growth restriction

Funded at University of Colorado Denver · NIH-11171322 · Data updated 2026-11-12

This study is looking at how being at high altitudes affects the growth of babies during pregnancy by checking the blood of moms and their babies to see how certain substances change, which could help us find ways to keep babies healthy in those conditions.

Who could benefit from this research

Could help

Ideal candidates for this research are pregnant individuals living at high altitudes who may be at risk for fetal growth restriction.

Less likely to help

Patients who are not pregnant or those living at low altitudes are unlikely to benefit from this research.

What this research studies

This research investigates how high-altitude conditions impact fetal growth by examining the role of purinergic signaling in blood flow regulation. Researchers will analyze maternal and fetal blood samples to identify differences in nucleotide metabolites at high altitudes compared to lower altitudes. The study aims to understand how these metabolites influence blood vessel behavior, particularly in the uterus and placenta, which are crucial for fetal development. By exploring these mechanisms, the research seeks to uncover potential interventions to improve fetal health in high-altitude pregnancies.

Why it matters

Potential benefit: If successful, this research could lead to improved strategies for preventing fetal growth restriction in pregnancies at high altitudes.

How similar studies have gone: Previous research has shown that understanding metabolic responses to hypoxia can lead to significant insights in fetal health, indicating potential for success in this novel approach.
