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 کاملPectin–Coated Polyethylenimine Polyplexes as Effective Gene Delivery Systems
Gene therapy is believed to be the therapy of the future because it aims to eradicate causes rather than symptoms of diseases. The generic aim of gene therapy is to deliver DNA inside cells in order to achieve a stable and regulated expression of transgenes in the target cells or tissues without side effects. Spontaneous entry of naked DNA inside cells is an inefficient process, consequently, a...
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...
متن کاملPolyethylenimine-grafted polycarbonates as biodegradable polycations for gene delivery.
Polycations as one of non-viral vectors have gained increasing attentions. In this paper, polyethylenimine(PEI)-grafted polycarbonates (PMAC-g-PEIx) were synthesized as a kind of biodegradable polycations for gene delivery. Backbone polymer, poly(5-methyl-5-allyloxycarbonyl-trimethylene carbonate) (PMAC), was synthesized in bulk catalyzed by immobilized porcine pancreas lipase (IPPL). Then, PMA...
متن کاملCross-linked polyethylenimine–tripolyphosphate nanoparticles for gene delivery
The high transfection efficiency of polyethylenimine (PEI) makes it an attractive potential nonviral genetic vector for gene delivery and therapy. However, the highly positive charge of PEI leads to cytotoxicity and limits its application. To reduce the cytotoxicity of PEI, we prepared anion-enriched nanoparticles that combined PEI with tripolyphosphate (TPP). We then characterized the PEI-TPP ...
