Figure 4From: Modeling cardiac β-adrenergic signaling with normalized-Hill differential equations: comparison with a biochemical modelPredicted dynamics and dose responses of the normalized-Hill β-adrenergic model. A) Predicted dynamics of G proteins (Gsα), cyclic AMP (cAMP), and phospholamban (PLB) phosphorylation in response to a transient norepinephrine (NE) exposure (NE = 1). B) Steady-state concentration responses of Gsα, cAMP and PLB to varying levels of NE.Back to article page
