Who could benefit from this research
✓Could help
Infants at risk for or diagnosed with bronchopulmonary dysplasia, particularly those with oxygen exposure history.
✕Less likely to help
Very premature infants without BPD or those not exposed to hyperoxia may see no direct benefit.
What this research studies
Bronchopulmonary dysplasia is a common problem in babies born early and is worsened by high oxygen exposure. This grant studies how reduced LKB1 and related AMPK signaling in lung endothelial cells may limit new blood vessel growth, contributing to BPD. Using neonatal mouse models, the researchers will explore how LKB1, AMPK, and mitochondrial biogenesis interact to drive angiogenesis in the lungs and whether activating AMPK can restore normal vessel formation. The work builds on prior findings that metformin can improve mitochondrial function and lung angiogenesis in hyperoxia, with the goal of translating these insights toward human therapies. Overall, the project seeks to map the molecular pathway from cellular energy sensing to blood vessel growth in the developing lung to inform future treatments for BPD.
Why it matters
Potential benefit: If successful, the findings could guide new therapies to promote lung blood vessel growth and reduce BPD severity in preterm infants.
How similar studies have gone: Previous studies showed that activating AMPK pathways can improve mitochondrial function and angiogenesis in experimental lung models, supporting this approach.
