What this research studies

The team is studying a protein called NPM1 that helps trigger cell death in kidneys when blood flow is reduced. They will map the part of NPM1 that binds to another protein, Bax, using protein-structure tools like x-ray crystallography and chemical cross-linking. Chemists will design and optimize short peptide drugs to stop the NPM1:Bax interaction, and the best candidates will be tested in kidney cells and animal models. The long-term aim is to pick a therapy that could prevent ischemic acute kidney injury in patients having high-risk cardiac surgery.

Who could benefit from this research

Good fit: Ideal candidates are people at high risk for ischemic acute kidney injury, for example patients undergoing high-risk cardiac surgery with expected periods of low kidney blood flow.

Not a fit: People whose kidney problems are caused by long-term chronic disease, toxins, infections, or non-ischemic causes are less likely to benefit from this specific approach.

Why it matters

Potential benefit: If successful, this work could lead to a new drug that prevents sudden kidney failure after episodes of low blood flow, such as during some heart surgeries.

How similar studies have performed: Previous research has linked NPM1 to ischemic kidney damage and shown effects across species, but using optimized peptides to block NPM1:Bax is a new and early-stage approach not yet proven in patients.
