JM2 Peptide Disrupts Glioblastoma Stem Cells and Slows Tumor Growth in Preclinical Models

Biodegradable nanoparticles are being tested to optimize JM2 delivery ahead of human studies.

Overview

  • The JM2 peptide selectively disrupts connexin43-microtubule interactions in glioblastoma stem cells, triggering their death while sparing normal brain cells.
  • In vivo experiments show that JM2 treatment significantly reduces tumor growth in mouse models of glioblastoma.
  • Researchers uncovered a novel role for cytoplasmic connexin43 in maintaining treatment-resistant stem cells, guiding the design of JM2.
  • Teams are exploring biodegradable nanoparticle and viral vector platforms to deliver JM2 directly to tumor sites.
  • Co-founders Samy Lamouille and Rob Gourdie formed Acomhal Research Inc. to license JM2 and advance it toward clinical trials.
