چکیده

Polymeric micelle prepared through the self-assembly of cationic cholesterol-modified gelatin was tested for siRNA delivery. It exerted the desired effect of gene knockdown in HeLa cells stably expressing the luciferase gene and achieved a two-fold increase in the knockdown ability when compared to Lipofectamine® 2000. It was found that the polymeric micelle exhibited excellent stability and increased the biological stability of the siRNA in serum.

Formulation of a therapeutic cationic liposome-siRNA complex for development to fight osteosarcoma

Introdution: Cationic liposomes have been presented for gene delivery as an alternative vector instead of viral vectors. A major challenge associated with siRNA delivery is the instability of liposomes, which is still a serious problem. The aim of this study was to provide an appropriate formulation to overcome this instability. Methods: In the present study (Scientific-Fundamental, Experiment...

Positively charged cholesterol–recombinant human gelatins foster the cellular uptake of proteins and murine immune reactions

PURPOSE Recombinant human gelatins with defined molecular weights were modified with cholesterol to make them amphiphilic in nature. We investigated the feasibility of these modified human gelatins acting as a carrier of antigenic proteins for inducing cellular immunity. The aim of this study was to synthesize novel and effective compounds for vaccine delivery in vivo. METHODS Two types of ch...

Evaluation of Small Interfering RNA Delivery into Cells by Reverse Transfection in Suspension with Cationic Liposomes

Successful gene silencing by small interfering RNA (siRNA) requires efficient uptake of siRNA into targeted cells. For in vitro transfection of siRNA using cationic liposomes, two types of transfection method are currently being used: conventional (forward; Fw) and reverse (Rev) transfections. Here, to investigate an efficient siRNA transfection method using cationic liposomes, we compared the ...

Highly Efficient Intracellular Protein Delivery by Cationic Polyethyleneimine-Modified Gelatin Nanoparticles

Intracellular protein delivery may provide a safe and non-genome integrated strategy for targeting abnormal or specific cells for applications in cell reprogramming therapy. Thus, highly efficient intracellular functional protein delivery would be beneficial for protein drug discovery. In this study, we generated a cationic polyethyleneimine (PEI)-modified gelatin nanoparticle and evaluated its...
