What this research studies

Researchers at the Medical University of South Carolina are studying how a protein called lysyl oxidase (LOX) makes triple-negative breast tumors resistant to chemotherapy and are designing small molecules to block it. They will use lab models including 3-D cell cultures and tumor samples to see whether blocking LOX improves drug penetration and reduces survival signals in cancer cells. The team will study both the structural tumor changes and cell-signaling pathways driven by LOX, and then generate prototype LOX inhibitors for preclinical testing. Results are intended to pave the way for future clinical trials combining LOX blockers with standard chemotherapy for people with TNBC.

Who could benefit from this research

Good fit: People diagnosed with triple-negative breast cancer, especially those whose tumors have not responded well to standard chemotherapy, would be the eventual candidates for therapies developed from this work.

Not a fit: Patients with non–triple-negative breast cancers or those seeking an immediately available therapy are unlikely to receive direct benefit from this preclinical research until clinical trials begin.

Why it matters

Potential benefit: If successful, this work could make standard chemotherapies more effective against triple-negative breast cancer and reduce treatment failure.

How similar studies have performed: Previous laboratory studies have linked LOX to chemotherapy resistance and early preclinical work suggests that targeting LOX can re-sensitize tumors, but selective LOX inhibitors for patients are still novel.
