The acquisition of radioresistance by esophageal squamous carcinoma (ESC) cells
during radiotherapy may lead to cancer recurrence and poor survival. Previous
studies have demonstrated that ionizing radiation (IR) induces
epithelial-mesenchymal transition (EMT) of ESC cells accompanied by increased
migration, invasion, and radioresistance. However, the underlying molecular
mechanisms of IR-induced EMT and radioresistance are not well established,
hampering the development of potential solutions. To address this issue, we
investigated the role of the IL-6/STAT3/TWIST signaling pathway in IR-induced
EMT. We found not only the pathway was activated during IR-induced EMT but also
STAT3 inhibition or Twist depletion reversed the EMT process and attenuated
radioresistance. These results improve our understanding of the underlying
mechanisms involved in IR-induced EMT and suggest potential interventions to
prevent EMT-induced acquisition of radioresistance.
