Immune Modulation of DUX4 in Cancer

DUX4 as predictive biomarker and therapeutic target to enhance the effectiveness of immunotherapies

  • Stage: Preclinical in vitro
  • Type: Diagnostic
  • Categories: Biomarker, Immuno Oncology, Target

Technology Overview

Although immune checkpoint blockade therapies represent important treatments for cancer, most patients are non-responders or may relapse. The efficacy of these treatments relies on cytotoxic T-cell recognition of antigens presented by MHC Class I on tumor cells and can be reduced by suppression of antigen presentation or blunt tumor-immune interactions. Fred Hutch researchers have discovered that DUX4, a double homeobox transcription factor expressed normally only early in development, is a novel regulator of antigen presentation and immune modulation. They found that DUX4 is re-expressed in solid tumors, is associated with anti-tumor activity, and promotes resistance to immune checkpoint blockade. Therefore, DUX4 is useful not only as a biomarker for identifying patients that may respond to immunotherapies, but also as a target to increase the effectiveness of immunotherapies.

Applications

  • Therapeutic target for cancer treatment
  • Therapeutic target to upregulate MHC Class 1 for use in combination with adoptive TCR-based T cell therapies
  • Predictive biomarker for immunotherapy response

Advantages

  • Reveals a molecular basis for DUX4 amplification in cancer cells
