A novel antisense oligonucleotide (ASO) carrier, polyethylenimine conjugated to linoleic acid (PEI-LA), was synthesized and evaluated for delivery of LOR-2501 to tumor cells. LOR-2501 is an ASO targeting ribonucleotide reductase R1 subunit (RRM1). In this study, PEI-LA was synthesized by reacting PEI (Mw ~ 800) with linoleoyl chloride. Gel retardation assay showed complete complexation between PEI-LA and LOR-2501 at N/P ratio above 8. No significant cytotoxicity was observed with these… Expand

TLDR
This novel formulation of FA/PEI-OA provides a reliable and highly efficient method for delivery of oligonucleotide and warrants further investigation. Expand
Delivery of antisense oligonucleotide using polyethylenimine-based lipid nanoparticle modified with cell penetrating peptide
TLDR
In vitro experiments suggested that Lp-PPRP had lower cytotoxic and higher transfection efficiency for delivering LOR-2501 compared with PEI, and potential utility of LP-P PRP in the development of ASO in tumor therapy is suggested. Expand
Polyethylenimine-based formulations for delivery of oligonucleotides.
TLDR
Various intelligent modifications of PEI such as pH responsive bond (hydrazone bond) and redox sensitive bond (disulfide bond) could accurately control oligonucleotides release and have attracted attention for efficient oligon nucleotides delivery. Expand
A novel reduction-sensitive modified polyethylenimine oligonucleotide vector.
TLDR
It is demonstrated that a reducibly degradable cationic polymer PEI-SS-OA possesses both higher oligonucleotide delivery efficiency and lower cytotoxicity than PEI (25 kDa), therefore is an attractive candidate for further in vivo evaluation. Expand
Antisense precision polymer micelles require less poly(ethylenimine) for efficient gene knockdown.
TLDR
A conceptual solution to the problem of antisense or siRNA delivery is to self-assemble these molecules into 'gene-like' micelles with high local charge and increased stability, thus reducing the amount of transfection agent needed for effective gene silencing. Expand

Cross-linked Small Polyethylenimines: While Still Nontoxic, Deliver DNA Efficiently to Mammalian Cells in Vitro and in Vivo
TLDR
Cross-linking of small PEIs with judiciously designed amide- and ester-bearing linkers boosts their gene delivery efficiency both in vitro and in vivo without increasing the cytotoxicity. Expand
Nonviral gene transfer into fetal mouse livers (a comparison between the cationic polymer PEI and naked DNA)
TLDR
The gene transfer efficacy of concentrated naked DNA was approximately 40 times higher in fetuses than in adults (0.8 × 103 RLU/mg of tissue protein), indicating that fetal tissue is especially amenable to the uptake and expression of naked DNA. Expand
A versatile vector for gene and oligonucleotide transfer into cells in culture and in vivo: polyethylenimine.
TLDR
Together, these properties make PEI a promising vector for gene therapy and an outstanding core for the design of more sophisticated devices because its efficiency relies on extensive lysosome buffering that protects DNA from nuclease degradation, and consequent lysOSomal swelling and rupture that provide an escape mechanism for the PEI/DNA particles.

Gene transfection of hyperbranched PEI grafted by hydrophobic amino acid segment PBLG.
TLDR
The experiments showed that PP can effectively condense pDNA into particles and suggested that the PP had much lower toxicity than PEI, and showed considerable potential as carriers for gene delivery. Expand
Polyethylenimine/DNA complexes shielded by transferrin target gene expression to tumors after systemic application
TLDR
It is shown that the positive surface charge of PEI (25 kDa branched or 22’kDa linear)/DNA complexes can be efficiently shielded by covalently incorporating transferrin at sufficiently high densities in the complex, resulting in a dramatic decrease in nonspecific interactions, eg with erythrocytes, and decreased gene expression in the lung. Expand
Optimized galenics improve in vitro gene transfer with cationic molecules up to 1000-fold.
TLDR
Gene transfer with a lipopolyamine (transfectam) in the presence of serum was increased over 10-fold by sequential addition of the lipid to DNA, and high complex concentrations led to large enhancements too, which points to the fact that formation of productive complexes is a slow process. Expand
