(A) Quantification of phospho-ERK1/2 (normalized to total ERK1/2 and β-actin) as assessed via Western blot. Exo-Fect + KrasG12D synthetic guide RNA1, n = 7 mice; n = 8 mice for all other groups. Data are presented as mean ± SEM. Kruskall–Wallis with Dunn’s multiple comparison test performed. (B) Quantitative PCR for WT Kras mRNA. Data are normalized to 18s and Exosomes + Exo-Fect control and presented as mean ± SEM. n = 5 mice per group. One-way ANOVA with Tukey’s multiple comparison test performed. (C) Full-length blots for phospho-ERK1/2, total ERK1/2, and β-actin. *P < 0.05, **P < 0.01.
