Article Title: Lipid nanoparticles and siRNA targeting plasminogen provide lasting inhibition of fibrinolysis in mouse and dog models of hemophilia A
doi: 10.1126/scitranslmed.adh0027
Figure Lengend Snippet: (A) Mice were injected with a single dose of siLuc (gray) or siPlg (teal blue). Plg mRNA in liver tissue was measured using qPCR, normalized against the housekeeping gene, Ppia. (B) Representative Western blot against plasminogen, where each lane contains the plasma from an individual mouse in either treatment group. The triangular marker indicates the expected molecular weight of plasminogen (92 kDa). (C) Plasminogen protein in plasma measured in a portion of the mice enrolled at each time point using densitometry, normalized to a loading control, and graphed relative to untreated mice. (D) Plasminogen protein in plasma quantified after administration of siPlg to dogs at 0.027 (purple, n = 3), 0.054 (green, n = 2), or 0.54 (teal blue, n = 1) mg siRNA/kg body weight. (E) Representative Western blot against plasminogen, where each lane contains plasma collected from a single WT dog at a different time point before or after siPlg administration at 0.054 mg/kg. Data are presented as mean ± SEM and were analyzed by two-tailed unpaired Student’s t test (A) or by two-way ANOVA (C); *P < 0.05.
Article Snippet: The membranes were treated with a primary antibody against plasminogen (1:1000; SAPG-AP; confirmed cross-reactivity: human, rat, mouse, rabbit, canine, and pig; Affinity Biologicals), washed, and treated with horseradish peroxidase–labeled anti-host secondary antibody (1:15,000; Abcam).
