The known FGF signaling pathways in chondrocytes annotated to reflect proteins identified in the inhibitory FGF signaling. Underlined proteins are present in the dataset of targets regulated by FGF1 in RCS cells. GSK3β is underlined with a dotted line, as its role in the inhibitory FGF signaling was determined because of initial identification of its downstream target, b-catenin.
