Paper Dual Strategies Based on Golgi Apparatus/Endoplasmic Reticulum Targeting and Anchoring for High-Effi
Peptide KDEL-grafted chondroitin sulfate CPD/siBcl-2/CK
Delivery Success Class yes
In Vivo Flag yes
Uptake Confirmed yes
Label Confidence high
In Vitro Functional Effect
Endosomal Escape Evidence yes
Peptide Concentration KDEL grafting ratio on chondroitin sulfate approximately 11%
Rna Concentration In vivo siRNA dose 1 mg/kg where applicable; exact in vitro siRNA concentration not fully specified for luciferase assay
Mixing Ratio CPD/siRNA/CK prepared by CPD/siRNA complexation followed by coating with KDEL-grafted chondroitin sulfate; C/Gu ratios screened, same strategy as CPD/siRNA/CS
Formulation Format polymer/polysaccharide nanocomplex
Formulation Components Cell-penetrating poly(disulfide) (CPD), siRNA, KDEL-grafted chondroitin sulfate (CK); CK provides CD44-associated targeting/Golgi transport and KDEL-mediated ER-directed sorting
Size Nm 167.20
Zeta Mv -13.60
Model Scope in_vivo
Model Type in vivo antitumor RNAi therapy
Cell Lines Or Primary Cells B16F10 melanoma cells
Animal Model C57BL/6 mice bearing subcutaneous B16F10 tumors
Administration Route intravenous injection; every 2 days for 5 doses
Output Type in vivo target-gene knockdown and tumor inhibition
Output Value Tumor inhibition rate 90.1%; tumor Bcl-2 expression downregulated to approximately 26%; apoptosis markers increased.
Output Units
Output Notes Functional in vivo Bcl-2 knockdown with tumor inhibition qualifies as delivery_success_class = 1. This row represents the KDEL/CK directed-sorting peptide strategy.
Toxicity Notes No abnormalities in main-organ HE staining; no significant changes in red/white blood cells, platelets, CRE, CK, UREA, or ALT versus controls were reported.
