miR-302 enhances the sensitization of breast cancer cells to ionizing radiation [16], miR-23b regulates autophagy associated with radioresistance of pancreatic cancer cells [17], and miR-205 mediates the PTEN/Akt pathway involved in both radiosensitive and radioresistant nasopharyngeal carcinoma cells [18]. This evidence concerns the gene AKT1 and nasopharyngeal carcinoma.
