Potent, cancer-targeted inhibitors of SUV39H1 to boost immune attack on tumors

Official title: Discovery of Potent Selective Inhibitors of the Histone Methyltransferase SUV39H1 for the Treatment of Cancer

Funded at Sanford Burnham Prebys Medical Discovery Institute · NIH-11377456 · Data updated 2026-11-12

A new drug approach aims to turn difficult cancers into ones that the immune system can better fight by disabling a key protein called SUV39H1.

Who could benefit from this research

Could help

Patients with cancers that are treated with immunotherapies and may benefit from combined strategies could be eligible in future trials.

Less likely to help

If the cancer does not rely on ERV/retrotransposon silencing or if SUV39H1 inhibitors are not effective, patients may not experience benefit.

What this research studies

This grant focuses on creating selective inhibitors of SUV39H1 to reactivate dormant genetic elements in cancer cells, which can wake up immune signals and attract immune cells to tumors. The project uses preclinical models to show that blocking SUV39H1 makes tumors more visible to the immune system and may work with existing immunotherapies. Researchers will test compound potency, selectivity, and how these inhibitors influence cancer cell behavior and immune pathways. If successful, this work could pave the way for combination therapies that help patients whose cancers do not currently respond well to today’s immunotherapies.

Why it matters

Potential benefit: If successful, patients could benefit from new drugs that enhance their immune system’s ability to attack cancer, potentially improving responses to immunotherapy.

How similar studies have gone: Preclinical studies have shown that inhibiting SUV39H1 can convert tumors from “cold” to “hot” and sensitize them to immunotherapies, supporting a plausible pathway for benefit.
