Cationic SLN for siRNA and DNA plasmid delivery in hepatocellular carcinoma

Hepatocellular carcinoma (HCC) is the sixth most common cancer worldwide and the third leading cause of cancer-related deaths. For the treatment of HCC several drugs are under development, but the only one with proven survival benefit is sorafenib. This agent is a multikinase inhibitor that blocks Raf signaling and VEGF, PDGF and c-Kit. It has antiproliferative and antiangiogenic activity and delays tumor progression [1,2]. Moreover, systemic tumor-targeted gene delivery is attracting increasing attention as a promising alternative to conventional therapeutic strategies. At this purpose a large number of viral and non-viral vectors have been studied and applied as systems of stable transfec…

Cationic solid lipid nanoparticles complexed with genetic material for liver tumor treatment

Concept Gene therapy is a growing field of medicine with great potential for the treatment of several diseases and it is based on the delivery of nucleic acids (DNA, RNA, etc.,) to specific cells. To achieve their therapeutic effects, the nucleic acids need to cross several biological barriers and be protected from the degradation by nucleases, present in biological fluids and intracellular compartments, to successfully gain access to their intracellular targets. To overcome these hurdles, it is necessary to deliver the genetic material with biocompatible carriers able to facilitate its translocation across the cell membranes and protect it from being degraded while circulating in the blood…

Delivery of shRNA plasmid DNA by cationic solid lipid nanoparticles for gene silencing in human hepatocarcinoma cells

PEGylated graphene oxide (GO-PEG) as new carrier for chemotherapeutic agent delivery

Graphene, a single layer of sp2 -hybridized carbon atoms arranged in a honeycomb two-dimensional (2-D) crystal lattice, has evoked enormous interest throughout the scientific community since its first appearance in 2004. Due to its unique structure and geometry, graphene possesses remarkable physical–chemical properties (including large specific surface area and biocompatibility) that enable it to be an ideal material for several of applications, ranging from quantum physics, nanoelectronics, energy research, catalysis and engineering of nanocomposites and biomaterials. In the area of nanomedicine, graphene and its derivatives can be exploited for a broad range of applications, including a …
