BACKGROUND Vectors based on human adenovirus serotype 5 (HAdV-5) continue to show promise as delivery vehicles for cancer gene therapy. Nevertheless, it has become clear that therapeutic benefit is directly linked to tumor-specific vector localization, highlighting the need for tumor-targeted gene delivery. Aberrant glycosylation of cell surface glycoproteins and glycolipids is a central featur...

BACKGROUND The success of gene transfection is largely dependent on the development of a vehicle or vector that can efficiently deliver a gene to cells with minimal toxicity. METHODS A liver cancer-targeted specific peptide (FQHPSF sequence) was successfully synthesized and linked with chitosan-linked polyethylenimine (CP) to form a new targeted gene delivery vector called CPT (CP/peptide). T...

ABSTRACT- In order to produce transgenic rice lines lacking selectable marker gene, biolistic co-transformation technique using gold nanoparticles was adopted. In the first step, the efficiency of different sizes of gold particles was evaluated. The results showed that the efficiency of the nanoparticles in the transformation was comparable to that of the micro particles. Subsequently, two sepa...

There is increasing trend in using recombinant stem cells as novel therapeutic candidates in different diseases. These studies encompass different applications from targeted homing of Mesenchymal Stromal (stem) Cells (MSC), to arming them with different cytokines. Resistance to transfection or transduction methods had urged researchers to look for better gene delivery alternates and optimizing ...

The efficient targeted delivery of nucleic acids in vivo provides some of the greatest challenges to the development of genetic therapies. We aim to develop nanocomplex formulations that achieve targeted transfection of neuroblastoma tumours that can be monitored simultaneously by MRI. Here, we have compared nanocomplexes comprising self-assembling mixtures of liposomes, plasmid DNA and one of ...

The construction of synthetic straightforward, biocompatible and biodegradable targeted drug delivery system with fluorescent tracking abilities, high anticancer activities and low side effects is still a challenge in the field of biochemistry and material chemistry. In this work, we constructed targeted paclitaxel (Taxol) delivery nanoparticles composed of permethyl-β-cyclodextrin modified hya...

Microspheres having free flowing powder characteristics, which are consisting of synthetic polymers and proteins. These biodegradable in nature particle size less than 200um. the multiparticulate drug delivery systems from natural material. received much attention not only for prolonged release, but also targeting anticancer drugs. In future by combining various other strategies, microspheres w...
