result sql = Cationic hyaluronic acid (HA)-modified DOTAP/DOPE liposomes were designed for the targeted delivery of anti-telomerase siRNA to CD44 receptor-expressing lung cancer cells DOTAP/DOPE : liposomes modified with 1%-20% (w/w) HA-DOPE conjugate were obtained by the ethanol injection method. Their size was below 170 nm and they exhibited zeta potentials higher than +50 mV. Lipoplexes prepared at different +/-ratios with siRNA were in the range of 200 nm and below and their zeta potentials were strongly dependent on the degree of modification and the +/-charge ratio. The presence of HA did not compromise binding, protection of siRNA from degradation, and complex stabilities in serum but rather resulted in an improvement of these properties. Liposome cytotoxicity, investigated by the MTT assay and LDH release after treatment of CD44(+) A549 cells and CD44(-) Calu-3, was demonstrated only at high concentrations. However, the addition of siRNA to HA-modified liposomes prevented cytotoxic effects compared to all other formulations. As shown by flow cytometry, transfection of siRNA into A549 cells was markedly improved with HA-modified liposomes, but not into Calu-3 cells. Using a qPCR-TRAP assay to test telomerase activity, no difference was demonstrated in the efficiency between HA-modified and nonmodified preparations. Moreover, some reduction in telomerase activity was observed with liposomes alone, lipoplexes prepared with nonsense siRNA and lipofectamine, indicative for some direct inhibitory effect of the lipids and siRNA on the expression of this enzyme. HA-modified DOTAP/DOPE liposomes represent a suitable carrier system for siRNA since properties like binding or protection of siRNA are not altered. They display an improved stability in cell culture medium and a reduced cytotoxicity. Furthermore, these novel lipoplexes could successfully be targeted to CD44-expressing A549 cells opening interesting perspectives for the treatment of lung cancer.
