Mitophagy responds to ionizing radiation but has little impact on how sensitive adenocarcinoma cells are to radiation

Abstract

Exposing adenocarcinoma cells to 5 Gy X-ray enhanced mitophagy activity and the expression of some mitophagy receptors.

  • Ionizing radiation induces damage not only in cell nuclei but also in mitochondria.
  • Mitophagy, the process of degrading impaired mitochondria, responds to ionizing radiation.
  • Pharmacological inhibition of mitophagy did not significantly alter the radiosensitivity of HCT116 and A549 cells.
  • Molecular targeting to inhibit mitophagy through BNIP3L knockdown also did not significantly change radiosensitivity, despite reduced mitophagy activity.
  • Data suggest that while mitophagy is activated by ionizing radiation, it plays a limited role in the radiosensitivity of adenocarcinoma cells.
