The inefficiency of non-viral gene delivery systems, relative to viral systems, is likely due, in part, to the failure of endosomes to release DNA before reaching degradative lysosomes. A solution is to incorporate compounds in a delivery vector that will selectively increase the release of endosomally encapsulated DNA. To meet the above criteria, we(More)
Maize is moderately sensitive to salt stress; therefore, soil salinity is a serious threat to its production worldwide. Here, excellent salt-tolerant maize inbred line TL1317 and extremely salt-sensitive maize inbred line SL1303 were screened to understand the maize response to salt stress and its tolerance mechanisms. Relative water content, membrane(More)
The impact of biodegradable pH-sensitive surfactant (BPS)-liposomes on nucleic acid, i.e., oligonucleotide and plasmid DNA, cellular delivery was examined. Fluorescein-labeled nucleic acids complexed with 1,2-dioleoyl-3-trimethylammonium propane cationic liposomes and BPS at a charge ratio (+/-) of 10 were incubated in CV-1 cells and analyzed by flow(More)
A variety of techniques are currently available to enhance the cellular uptake and pharmacological effectiveness of antisense oligonucleotides in the in vitro setting. The choice of technique will depend on the context of investigation, the likelihood of cytotoxity due to the delivery agents, and the ease and convenience of the approach. The considerations(More)
The use of oligonucleotides (ONs) for gene therapy of certain diseases has been discussed since the late 1970s. ONs are single stranded chains of nucleic acids that can hybridize with target nucleic acid sequences to inhibit specific proteins, and therefore allow selective treatment of various diseases. The use of ONs is limited due to their instability in(More)
