The current methods for treatment of cancers are inadequate and more specific methods such as gene therapy are in progress. Among different vehicles, cationic liposomes are frequently used for delivery of genetic material. This investigation aims to prepare and optimize DOTAP cationic liposomes containing an antisense oligonuclotide (AsODN) against protein kinase C alpha in non-small cells lung...

The development of efficient and safe carrier system to transfer DNA into cells is essential in non-viral gene therapy. The aim of the present study was to evaluate the effect of linear polyetheneimine (lPEI) (2500 Da) on the physicochemical and biological properties of lipopolyplexes constructed from liposomes and lPEI. Materials and Methods Different lipopolymers were synthesized from lPEI ...

Oligonucleotides able to hybridize bacterial RNA via in situ hybridization may potentially act as new antimicrobials, replacing antibiotics, and fast vivo diagnostic probes, outperforming current clinical methodologies. Nonetheless, oligonucleotides are not efficiently permeate the multi-layered envelope reach their target cytosol. Cationic fusogenic liposomes here suggested vehicles enable int...

Delivery of oligonucleotides has been a major impediment in the development of nucleic acid based drugs. In this report, we show that neomycin, an aminoglycoside antibiotic, when combined with a cationic lipid preparation such as DOTAP, enhances transfection efficiency of both reporter plasmids and oligonucleotides and results in a significant increase in transgene expression. The results descr...
