Boosting heart muscle and blood vessel repair by targeting Shh/Gli1 and Etv2 signals

Project 2 - Shh and Etv2 Signaling Pathways and Cardiovascular Repair in Mouse and Pig

NIH-funded research University of Alabama at Birmingham · NIH-11141891

Researchers are trying to see whether boosting specific signals (Shh/Gli1 and Etv2) can help adult hearts regrow muscle and blood vessels after injury.

What this research studies

This project uses mouse and pig models and specialized genetic tools to study how the Shh pathway (through Gli1/Gli2) and the Etv2 factor drive heart muscle cell and blood vessel growth after damage. The team will combine laboratory experiments with bioinformatics algorithms to map the genes and signaling networks that trigger regeneration. Large-animal pig studies will test whether manipulating these pathways improves heart repair after injury. Results are intended to identify biological targets that could guide future therapies for people recovering from heart attacks.

Who could benefit from this research

Good fit: Adults who have had a heart attack or have ischemic heart disease and who are interested in regenerative treatment approaches could be future candidates for therapies developed from this research.

Not a fit: Patients needing immediate, approved treatments or those with non-cardiac conditions are unlikely to receive direct benefit from the current animal-focused research.

Why it matters

Potential benefit: If successful, this work could point to new therapies that help damaged hearts regrow muscle and blood vessels and improve recovery after myocardial infarction.

How similar studies have performed: Prior animal work in newts and mice has shown that Shh/Gli1 and Etv2 can stimulate cardiomyocyte proliferation and angiogenesis, but translation to human treatments has not yet been proven.
