We previously reported an effective BMPCa cells-targeting cationic polypeptide gene carriermodified with peptide (T7, amino acid sequence: HAIYPRH) that could directly transferplasmid DNA (pDNA, pPMEPA1) into PCa cells, actively targeting to over expressingtransferrin receptors (TfR) in PCa cells (Lu et al., 2018). This evidence concerns the gene TFRC and posterior cortical atrophy.
