How the ASK1 protein influences lung scarring in men and women

Sex differences in ASK1-mediated pulmonary fibrosis

NIH-funded research Charlie Norwood VA Medical Center · NIH-11109429

This work looks at whether the cell protein ASK1 drives lung scarring after injury and whether it acts differently in men versus women.

What this research studies

The team will study how ASK1, a stress-activated protein, contributes to the scarring process that causes pulmonary fibrosis and why the disease is more common in men. Researchers will use laboratory models that mimic lung injury and fibrosis, examine ASK1-linked signaling pathways (including p38 and ERK1/2), and explore how sex hormones alter these responses. The work will analyze cell death, inflammation, and the behavior of scar-forming cells to map how ASK1 promotes fibrosis. Results are intended to point toward targets for therapies that could prevent or slow lung scarring.

Who could benefit from this research

Good fit: People with pulmonary fibrosis or scarring after severe lung injury (including post-COVID survivors) and U.S. Veterans with lung fibrosis would be the most directly relevant patient groups.

Not a fit: Patients without lung fibrosis or whose lung problems are caused by unrelated conditions are unlikely to benefit directly from this basic science work.

Why it matters

Potential benefit: If successful, this could point to new treatments that limit or prevent lung scarring and help tailor therapies for men and women.

How similar studies have performed: Related research has linked ASK1 to scarring in other organs and ASK1-blocking drugs have been tested elsewhere with mixed results, so applying this specifically to lung fibrosis is relatively new.
