Deep dives
Mechanisms of Tumor Dormancy
Research indicates that certain breast cancer cells can enter a dormant state, remaining inactive for extended periods before potentially becoming metastatic. The study highlights that this dormancy is influenced by signaling changes in small cell clusters known as tumor emboli, which detach from the primary tumor and circulate through the bloodstream. Specifically, the research identified reduced activity of the metabolic regulator mTOR and structural alterations in e-cadherin, a molecule important for cell adhesion, as key factors in maintaining this dormant state. These findings underscore the complexity of tumor behavior and encourage further exploration into how manipulating these pathways could prevent cancer recurrence.
