NF-κB induction in MyD88−/− cardiomyocytes. Cfb RNA was quantified from WT and MyD88−/− cultured neonatal cardiomyocytes after 12 h treatment with LPS (A) or TNF-α (B). Expression was compared by ΔΔCT method and statistical analyses performed using One-way ANOVA and Bonferroni’s post-test. For testing role of MyD88 in NF-κB induction, cultured neonatal cardiomyocytes from WT (C) and MyD88−/− (C and D) mice were transfected with an NF-κB-luciferase reporter plasmid. After 48 h of transfection, cells were treated with 10 µg per ml LPS (C) or 4 µg per ml poly(I:C) (D) for indicated time. Controls (Ctr) were left untreated. Luciferase activity from a Renilla luciferase reporter was used as a control for transfection efficiency.
