Systematic Study of a Library of PDMAEMA-Based, Superparamagnetic Nano-Stars for the Transfection of CHO-K1 Cells.

The introduction of the DNA into mammalian cells remains a challenge in gene delivery, particularly in vivo. Viral vectors are unmatched in their efficiency for gene delivery, but may trigger immune responses and cause severe side-reactions. Non-viral vectors are much less efficient. Recently, our group has suggested that a star-shaped structure improves and even transforms the gene delivery capability of synthetic polycations. In this contribution, this effect was systematically studied using a library of highly homogeneous, paramagnetic nano-star polycations with varied arm lengths and grafting densities. Gene delivery was conducted in CHO-K1 cells, using a plasmid encoding a green fluore…

PREPARAZIONE E CARATTERIZZAZIONE DI NANOSISTEMI LIPIDICI PER IL DIREZIONAMENTO E IL RILASCIO MODIFICATO DI FARMACI E ACIDI NUCLEICI IN TERAPIA ONCOLO…

sono stati sviluppati sistemi nanoparticellari in grado di intrappolare elevate quantità di farmaci e di legare materiale genico. I sistemi preparati sono stati caratterizzati da un punto di vista chimico-fisico e tecnologico farmaceutico. Sono stati infine utilizzati per prove in vitro e i risultati ottenuti hanno mostrato che essi possiedono le caratteristiche per potere essere considerati dei validi carrier per farmaci e materiale genico nel trattamento oncologico.

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…
