Fibroblast Growth Factor 21(FGF-21) is a member of the fibroblast growth factor (FGF) family and it is involved in the modulation of cell proliferation, growth, and differentiation as well as cell metabolism. This protein is a secreted endocrine factor that functions as a major metabolic regulator, and stimulates the uptake of glucose in adipose tissue. FGF21 binds to FGFR1c complexed with β-Klotho expressed in adipocytes to activate the canonical FGF signaling pathway (ERK1/2) and the AMPK/PGC1α pathway. Therefore, FGF-21 is being pursued as a therapeutic target for diabetes and obesity.
Measured in a cell proliferation assay using NIH-3T3 mouse embryonic fibroblast cells. The EC50 this effect is less than 0.2μg/ml in the presence of 2μg/ml recombinant Klotho β and 20μg/ml heparin.
