Targeting cell-division proteins (TTK and NEK2) for aggressive triple-negative breast cancer in Hispanic/Latina patients
Targeting centrosome‐mitotic kinases as a novel therapeutic approach against breast cancers in Hispanic/Latinas.
This project tests drugs that block two cell-division proteins (TTK and NEK2) to try to slow aggressive triple-negative breast cancer in Hispanic/Latina patients.

What this research studies
As a patient, I would know the team is studying tumor samples from Tampa and Puerto Rico to see if TTK and NEK2 are linked to aggressive triple-negative breast cancer in Hispanic/Latina people. They will use tissue microarrays and lab assays to measure these proteins and their connections to chromosome instability and EMT. In lab models they will block TTK and NEK2 to see if that reduces cell division errors, migration, and invasion and whether it can restore sensitivity to drugs like Palbociclib. The researchers will compare results across different ancestral backgrounds to understand why outcomes are worse in patients with African genomic ancestry in their catchment areas.
Who could benefit from this research
Good fit: Ideal participants are people diagnosed with triple-negative breast cancer, particularly Hispanic/Latina patients or those from the Tampa and Puerto Rico catchment areas.
Not a fit: Patients with hormone-receptor-positive or HER2-positive breast cancers, or whose tumors do not show TTK/NEK2 dysregulation, are unlikely to benefit from these specific targeted approaches.
Why it matters
Potential benefit: If successful, this work could lead to new targeted therapies that slow tumor growth, reduce spread, and improve outcomes for Hispanic/Latina patients with triple-negative breast cancer.
How similar studies have performed: Laboratory studies by the team show that inhibiting TTK and NEK2 reduces migration and may restore drug responses in cells, but this approach has not yet been proven effective in patients.
