How CRIPTO helps breast cancer cells adapt and spread

Coordination of stress-adaptive cell states by CRIPTO in breast cancer heterogeneity and progression

NIH-funded research Utah State Higher Education System--University of Utah · NIH-11262894

This project looks at whether blocking a protein called CRIPTO can keep breast cancer cells from changing in ways that help tumors resist treatment and spread.

What this research studies

Researchers are studying a protein called CRIPTO (also called CR1) that appears to help breast cancer cells switch into stress-adaptive states that fuel relapse and metastasis. They will use human breast cancer cells grown in lab models, 3-D culture systems, and animal models to see how CRIPTO controls cell behavior and interactions with surrounding tissue. The team will test a candidate peptide drug (A4Fc) that blocks CRIPTO and measure effects on tumor growth, fibrosis, and spread. Molecular tools like ATAC-seq and signaling studies will be used to understand the mechanisms behind these changes.

Who could benefit from this research

Good fit: People with breast cancer—especially those with aggressive or treatment-resistant tumors—would be the most relevant group for future clinical testing based on this research.

Not a fit: People without breast cancer or with tumors that do not rely on CRIPTO-related signaling are unlikely to receive direct benefit from this work.

Why it matters

Potential benefit: If successful, this work could lead to new therapies that stop cancer cells from adapting to stress and reduce treatment resistance and metastasis in breast cancer.

How similar studies have performed: Preclinical studies reported by the team showed that blocking CRIPTO with the A4Fc peptide reduced tumor growth under stress and blocked metastasis in mouse models, but human testing has not yet been done.
