(A) RAW 264.7 macrophages were pretreated with drug at 10 μM and inflammatory signaling was induced for 24 h using LPS. Expression of NF-κB–regulated inflammatory genes (Il1b and Il6) was assayed by qRT-PCR. (B) IL1B and IL6 protein levels were assayed in media from the same experiment via AlphaLISA assay. (C) Primary cardiomyocytes were pretreated with vehicle, vamorolone, or the GR-specific ligand deflazacort, and inflammatory signaling induced with TNF. NF-κB–regulated inflammatory gene expression (Il1b and Il6) was assayed by qRT-PCR. (D) IL6 protein levels were assayed by AlphaLISA. (E) HL-1cells were pretreated with 10 μM drug and induced with TNF for 24 h. Expression of Il6 was assayed by qRT-PCR. (n = 4, **P < 0.005, ****P < 0.0001, ANOVA with post hoc versus [+] TNF control in gray; [−] = no TNF control, [+] = TNF plus vehicle, D = deflazacort, P = prednisolone, V = vamorolone, E = eplerenone).
