Paper Anti-cancer effect of R3V6 peptide-mediated delivery of an anti-microRNA-21 antisense-oligodeoxynucl
Peptide R3V6
Delivery Success Class yes
In Vivo Flag yes
Uptake Confirmed no
Label Confidence high
In Vitro Functional Effect
Endosomal Escape Evidence
Peptide Concentration not reported as molarity; complex prepared by weight ratio
Rna Concentration 40 µg antisense-ODN per intratumoral injection
Mixing Ratio antisense-ODN:R3V6 weight ratio 1:30
Formulation Format noncovalent peptide micelle/antisense-ODN complex
Formulation Components R3V6 amphiphilic peptide complexed with anti-miR-21 antisense-ODN
Size Nm
Zeta Mv
Model Scope in_vivo
Model Type in vivo glioblastoma xenograft therapeutic delivery
Cell Lines Or Primary Cells
Animal Model C6 glioblastoma subcutaneous xenograft in male BALB/c nude mice
Administration Route intratumoral injection every 7 days; three total injections
Output Type in vivo miR-21 knockdown, PDCD4 induction, apoptosis, tumor growth inhibition
Output Value anti-miR-21/R3V6 significantly reduced miR-21 levels, increased PDCD4 staining, induced tumor apoptosis, and suppressed tumor growth/tumor weight compared with controls
Output Units
Output Notes delivery_success_class = 1 because functional in vivo anti-miR-21 delivery was demonstrated by reduced tumor miR-21, downstream PDCD4 induction, apoptosis, and tumor growth suppression. Scr-antisense-ODN/R3V6 control did not show significant tumor inhibition.
Toxicity Notes No significant body-weight differences among animal groups, suggesting no obvious systemic toxicity under intratumoral dosing.
