Paper Mechanisms of Nanoparticle-Mediated siRNA Transfection by Melittin-Derived Peptides
Peptide p5RHH
Delivery Success Class no
In Vivo Flag no
Uptake Confirmed no
Label Confidence high
In Vitro Functional Effect yes
Endosomal Escape Evidence yes
Peptide Concentration p5RHH stock 10 mM; peptide:siRNA ratio 100:1
Rna Concentration combined siRNA formulation tested across dose range; IC50 ~50 nM for viability effect
Mixing Ratio peptide:siRNA 100:1
Formulation Format albumin-stabilized peptide/siRNA nanocomplex with two siRNA cargoes
Formulation Components p5RHH nanoparticles simultaneously carrying p65 and p100/p52 siRNAs
Size Nm 55.00
Zeta Mv
Model Scope in_vitro
Model Type in vitro dual-target functional assay
Cell Lines Or Primary Cells F8 cells, murine model of HTLV-1-induced adult T-cell leukemia/lymphoma
Animal Model
Administration Route cell culture transfection
Output Type synergistic cell viability reduction after dual NFκB knockdown
Output Value Dual formulation targeting p65 and p100/p52 reduced F8 cell viability more strongly than either single siRNA, with reported IC50 around 50 nM
Output Units
Output Notes Multiple cargoes were used in the same peptide complex, so this is curated as a separate dual-cargo row. Functional in vitro activity was demonstrated, but no in vivo functional delivery was shown.
Toxicity Notes Scrambled siRNA showed no toxicity/viability reduction
Curation Notes
