Investigating lipopolymers based on polyethylenimine and nanoliposome for gene delivery to prostate cancer (PC3) cell line
Background: Non-viral Nano carriers such as liposomes and cationic polymers based on engineered properties are regarded in gene delivery field. Although these carriers do not have weaknesses of viral vectors, but they are less efficient than viruses and they still need to be improved as favorable gene delivery carriers. Amongst non-viral carriers, cationic liposomes have been proposed for clini...
متن کاملEnhanced tumor-targeted gene delivery by bioreducible polyethylenimine tethering EGFR divalent ligands.
This work demonstrates successful delivery of a gene to EGFR-overexpressed cancer cells by using a rationally designed branched GE11 peptide as a targeting ligand. In addition, we exploited the effect of the divalent structure of the branched GE11 peptide on the gene delivery and tumor targeting efficiency, compared to the monovalent GE11 peptide. The GE11 or branched GE11-tethered polymers wer...
متن کاملMannose polyethylenimine conjugates for targeted DNA delivery into dendritic cells.
Cell surface-bound receptors represent suitable entry sites for gene delivery into cells by receptor-mediated endocytosis. Here we have taken advantage of the mannose receptor that is highly expressed on antigen-presenting dendritic cells for targeted gene transfer by employing mannosylpolyethylenimine (ManPEI) conjugates. Several ManPEI conjugates were synthesized and used for formation of Man...
متن کاملPolyethylene glycol-grafted polyethylenimine used to enhance adenovirus gene delivery.
An improved adenoviral-based gene delivery vector was developed by complexing adenovirus (Ad) with a biocompatible, grafted copolymer PEG-g-PEI composed of polyethylene glycol (PEG) and polyethylenimine (PEI). Although an Ad-based gene vector is considered relatively safe, its native tropism, tendency to elicit an immune response, and susceptibility to inactivating antibodies makes the virus le...
متن کاملEffective in vitro gene delivery to murine cancerous brain cells using carbon nanotube-polyethylenimine conjugates
Objective(s): Carbon nanotube (CNT) has been widely applied at molecular and cellular levels due to its exceptional properties. Studies based on conjugation of CNTs with biological molecules indicated that biological activity is preserved. Polyethylenimine (PEI) is explored in designing novel gene delivery vectors due to its ability to condense plasmid DNA through electrostatic attraction. In t...
