Human serum albumin (HSA) coated lipid nanoparticles (HSA-LNPs) loaded with
phrGFP-targeted siRNA (HSA-LNPs-siRNA) were prepared and evaluated for gene
downregulation effect in phrGFP transfected breast cancer cells and the
corresponding xenograft tumor model. HSA-LNPs-siRNA were successfully prepared
with a particle size of 79.5±5.5 nm. In phrGFP transfected MCF-7 cells,
HSA-LNPs-siRNA significantly decreased cell fluorescence even in the presence of
FBS. Moreover, cell fluorescence and phrGFP mRNA expression were significantly
downregulated by HSA-LNPs-siRNA in phrGFP transfected MCF-7, MDA-MB-231 and
SK-BR-3 cells compared to control or HSA-LNPs-siRNA (scrambled). In phrGFP
transfected MCF-7 xenograft tumor model, tumor fluorescence was significantly
decreased after three times i.v. administration of HSA-LNPs-siRNA at a dose of 3
mg/kg compared to siRNA alone. HSA-LNPs-siRNA demonstrated a superior
pharmacokinetic profile compared to siRNA at dose of 1 mg/kg. These results show
that the novel non-viral carrier, HSA-LNPs, may be used for the delivery of siRNA
to breast cancer cells.
