BRD4 and lung carcinoma: Herein, a novel style of versatile nano‐PROTAC (CREATE (CRV‐LLC membrane/DS‐PLGA/dBET6)) is developed, which is constructed by using a pH/GSH (glutathione)‐responsive polymer (disulfide bond‐linked poly(lactic‐co‐glycolic acid), DS‐PLGA) to load BRD4‐targeted PROTAC (dBET6), followed by the camouflage with engineered lung cancer cell membranes with dual targeting capability.
