Stopping tumor 'stem cells' that drive malignant peripheral nerve sheath tumors

Targeting the Cancer Stem Cells in Malignant Peripheral Nerve Sheath Tumor

['FUNDING_R37'] · MEDICAL COLLEGE OF WISCONSIN · NIH-11159749

This project aims to block a signaling loop that helps cancer 'stem cells' start and spread malignant peripheral nerve sheath tumors to slow tumor growth and metastasis for people with MPNST.

What this research studies

Researchers will study tumor samples from people with MPNST and use mouse models to find a small population of stem-like tumor cells that can seed new tumors and metastases. They will focus on a nerve-related signaling loop (NRG1–ERBB3–CD44) that appears to help these cells survive and spread. In mice they will test ways to disrupt that loop and watch whether treated tumors form less often or send out fewer metastases. The work combines analysis of human tumors, genetic labeling in mouse models, and functional tests of tumor initiation and spread.

Who could benefit from this research

Good fit: People diagnosed with malignant peripheral nerve sheath tumor (MPNST), including those with NF1-associated disease or recurrent/metastatic MPNST, would be the most relevant candidates for related clinical approaches.

Not a fit: People with unrelated cancer types or tumors that are not driven by the NRG1–ERBB3–CD44 pathway are unlikely to benefit directly from this project.

Why it matters

Potential benefit: If successful, this work could point to new treatments that prevent tumor start and reduce metastasis in patients with MPNST.

How similar studies have performed: Therapies targeting ERBB-family signaling have helped other cancers, but targeting the specific NRG1–ERBB3–CD44 loop in MPNST is largely new and not yet proven.
