BECN1 and breast neoplasm: This toxicity was mitigated by coating QDs with 3‐mercaptopropionic.[236] Upregulation of Beclin‐1 and LC3‐II was reported for Hederagenin‐loaded black phosphorus QDs (BPQDs) coated by platelet membranes in breast tumors.[240] Cetuximab‐decorated Ag2S QDs (mPEG–Ag2S–Cet) enhanced 5‐FU efficacy by inhibiting 5‐FU‐induced cytoprotective autophagy in A549 cells.[239] Furthermore, cetuximab improved targeting specificity toward EGFR‐overexpressing cells.
