Han et al found that autophagy inhibitors increased the sensitivity of MDA‐MB‐231 breast cancer cells to radiation by inhibiting the activation of TAK1 after irradiation, suggesting that regulating TAK1 may be an effective way in treating radiation‐resistant breast cancer.53 Sun et al54 have found that MiR‐200c inhibited autophagy and enhanced radiosensitivity in breast cancer cells by targeting UBQLN1. Here, UBQLN1 is linked to breast cancer.
