Hepatic expression of the inflammatory cytokine IL‐6 mRNA was significantly lower in both the flox‐Fgf23/Dmp1‐Cre+/− groups treated with AD + FC compared to those receiving AD‐only (Figure 3a), suggesting that FC may be protective for upregulation of IL‐6 mRNA. The gene discussed is FGF23; the disease is Alzheimer disease.
