Development of nanocarrier for gene delivery to improve cellular uptake

Nanolipoparticles-mediated MDR1 siRNA delivery: preparation, characterization and cellular uptake

Objective(s): Lipid-based nanoparticles (NLP) are PEGylated carriers composed of lipids and encapsulated nucleic acids with a diameter less than 100 nm. The presence of PEG in the NLP formulation improves the particle pharmacokinetic behavior. The purpose of this study was to prepare and characterize NLPs containing MDR1 siRNA and evaluate their cytotoxicity and cellular uptake. MDR1 siRNA coul...

ethosome: a nanocarrier for transdermal drug delivery

ethosomes are a novel and alternative drug delivery systems and currently the focus of many research activities. ethosomes are soft, flexible vesicles that are composed mainly of phospholipids, ethanol and water. ethosomes can provide better skin permeation than liposomes and deliver enhanced amounts of both small and large therapeutic agents through skin and targeting to deeper skin layers for...

modification of chitosan to improve its biophysical properties for gene delivery applications

A surface-adaptive nanocarrier to prolong circulation time and enhance cellular uptake.

Based on the protonation/deprotonation of poly(β-amino ester) (PAE), mixed-shell micelles (MSMs) with adaptive surfaces could rapidly and reversibly change surface properties to prolong circulation time in blood (pH 7.4) and enhance cellular uptake at tumor sites (pH 6.5).

construction of peg-pamam dendrimer-based tag72-targeting nanocarrier for t-bid gene delivery to colorectal tumor cells

objective: the objective of this study is to develop and assess targeted pamam-peg nanocarrier with anti-tag72 nanobody for t-bid gene coding construct delivery into the human colonic adenocarcinoma cells. materials and methods: nanobody (nb) coding sequence was subcloned into psj expression vector for large-scale production and then nb was purified by ni++ affinity chromatography. sds-page an...
