A transient MXD4-dependent proliferative pause enables survival of brain micrometastases.
A transient MXD4-dependent proliferative pause enables cancer cells to survive early brain colonization, preventing progression to macrometastases in metastasis models.
- Why it matters: Understanding how metastasis-initiating cells survive initial stresses is crucial for preventing metastatic spread and relapse, yet this adaptive process was previously unknown.
- What they did: The study identified a temporary proliferative arrest mediated by MXD4 in aggressive cancer cells during early brain colonization, using genetic disruption, human tissue analysis, and patient-derived models.
- The result: Targeting this proliferative pause with existing drugs offers new preventive therapies to halt brain metastasis progression and improve patient outcomes.
