Fig. 1From: The inhibition of human lung fibroblast proliferation and differentiation by Gs-coupled receptors is not predicted by the magnitude of cAMP responseInhibition of ERK1/2 phosphorylation and proliferation. Concentration effect curves for forskolin-mediated inhibition of ERK phosphorylation, and PD0325901-mediated inhibition of proliferation in HLF in the presence of 3 ng/mL PDGF. For each individual experiment, data were normalised to the maximum amount of ERK phosphorylation or proliferation after addition of 3 ng/mL PDGF, and are expressed as means ± SEM for 4 independent experimentsBack to article page
