SLC38A7 and cancer: It is noteworthy that previous nanoparticle‐based approaches for cancer starvation therapy primarily focus on glucose consumption or amino acid transporter blockage, while we for the first time developed a coordination system targeting protein catabolism.[27] According to the results, the pH‐responsive THPMA moiety facilitated drug release in acidic environment (Figure 6D).[18a] The dual‐drug polymersomes (EBNPs) exerted higher anti‐cancer effect compared with free‐drug administration or single‐drug polymersomes (ENPs or BNPs) (Figure 7B–D).
