5΄ -(E)-vinylphosphonate modification enhances hsiRNA efficacy in liver, kidneys and heart column scatter plots showing Ppib or Htt mRNA levels in the livers, kidneys and hearts of mice (n = 5 per group) treated with 5΄-hydroxyl (5΄-OH), 5΄-phosphate (5΄-P), or and 5΄-(E)-vinylphosphonate (5΄-VP) hsiRNAs by intravenous (IV) of subcutaneous (SC) injection. mRNA levels measured by QuantiGene® 2.0 assay, were normalized to Hprt mRNA and expressed as percent of mRNA levels in PBS-treated animals. NTC, non-targeting control. T, targeting hsiRNA. Significance calculated by ANOVA with Bonferroni΄ s correction: ns, non-significant; *P ≤ 0.05; **P ≤ 0.01; ***P ≤ 0.001 and ****P ≤ 0.0001.
