Fibroblast Growth Factor (acidic) (FGF-1)
Responses to ligand
|Ligand family||FGF ligand|
|HMS LINCS ID||200860|
|Molecular weight||17 kDa|
Time course response
Fold-change response of pERK and pAKT following 10, 30 or 90 minutes treatment with FGF-1 at 1ng/ml (left) or 100ng/ml (right). Colored trajectories represent the indicated cell lines and all remaining cell lines are gray. Non-significant responses (below ~1.2-fold) are set to 1.
(Left) Distribution of the pathway bias across cell lines for FGF-1 (in black) and 2 reference ligands (IGF-1, yellow; and EGF, red) where the bias is defined as the arctangent of the ratio of the pAKT to pERK fold change responses (maximum across the three time points at 100ng/ml). (Right) Distribution of the pathway bias for all ligands that exhibited a least 50% significant responses across all cell lines when stimulated at 100ng/ml. Ligands are sorted according the median of the pathway bias and colored as in the left panel.
Fold change pERK (left) and pAKT (right) responses following treatment with FGF-1 at 1ng/ml and 100ng/ml (maximum response across 10, 30 and 90 minutes). Colored trajectories represent the indicated cell lines and all remaining cell lines are gray. Non-significant responses (below ~1.2-fold) are set to 1.
Distribution of sensitivity classes by ligands for pERK (left) and pAKT (right): ‘Equal’ (red) means that the fold change response at low dose is at least 75% of the high dose response; ‘100ng>1ng’ (blue) means that low dose response is statistically significant but less than 75% of the high dose response; ‘only 100ng’ (yellow) means that only the high dose response is significant.
Distribution of the kinetics of the responses at 100mg/ml for FGF-1 (left) and the different ligand families (ErbB ligands, Ins/IGF ligands, FGF-1/2, and all remaining ligands) for pAKT (top) and pERK (bottom). Kinetics classes are determined by an unsupervised k-means clustering of the time-series data that identified trajectories that correspond to sustained, transient, late, or no response.
