Figure 2From: Synovial DKK1 expression is regulated by local glucocorticoid metabolism in inflammatory arthritisRegulation of DKK1 expression by glucocorticoids. (A) Time course for induction of DKK1 protein expression by synovial fibroblasts (FLS) in response to dexamethasone or TNFα. (B) Dose response curves for the secretion of DKK1 in response to dexamethasone (expressed relative to baseline expression). *P < 0.05, **P < 0.01 relative to control.Back to article page
