Manipulating Radiation‐Sensitive Z‐DNA Conformation for Enhanced Radiotherapy

DNA double-strand breaks (DSBs) yield highly determines radiotherapy efficacy. However, improving the inherent radiosensitivity of tumor DNA to promote radiation-induced DSBs remains a challenge. Using theoretical and experimental models, the underexplored impact of Z-DNA conformations on radiosensitivity, yielding higher DSBs than other DNA conformations, is discovered. Thereout, a radiosensitization strategy focused on inducing Z-DNA conformation, utilizing CBL@HfO
