STAT3 pathway as a target for uterine fibroids

The STAT3 Pathway in Uterine Leiomyoma: A Therapeutic Target

NIH-funded research Northwestern University · NIH-11248829

This project will see if blocking the STAT3 pathway can shrink or slow uterine fibroids in people whose tumors carry MED12 mutations.

What this research studies

Researchers found that MED12 mutations, which cause most uterine fibroids, disrupt CDK8/19 control of STAT3 and may let STAT3 drive tumor growth and fibrosis. The team will use patients' tumor samples, CRISPR-modified cells, and laboratory models to study how STAT3 activity changes in MED12-mutated fibroids. They will test drugs and genetic approaches that block CDK8/19 or STAT3 to see whether that reduces tumor cell growth or fibrosis. The work aims to provide proof-of-concept for a targeted medical therapy for the MED12-mutated fibroid subtype.

Who could benefit from this research

Good fit: People with symptomatic uterine fibroids, especially those with tumors known or suspected to carry MED12 mutations, are the likely candidates for related clinical trials.

Not a fit: People whose fibroids do not have MED12 mutations or who need immediate surgical treatment may be less likely to benefit from STAT3-targeted approaches.

Why it matters

Potential benefit: Could lead to a new targeted medicine that shrinks or controls MED12-mutated uterine fibroids and reduces the need for surgery.

How similar studies have performed: Targeting STAT3 or related kinases has shown promise in preclinical models and some other cancers, but applying this strategy specifically to MED12-mutated uterine fibroids is largely novel and early-stage.
