Fibroblast growth factor protein was first purified in 1975, but soon afterwards others using different conditions isolated acidic FGF, Heparin-binding growth factor-1, and Endothelial cell growth factor-1. [7] Gene sequencing revealed that this group was actually the same growth factor and that FGF1 was a member of a family of FGF proteins.
A mitogenic growth factor activity was found in pituitary extracts by Armelin in 1973 [14] and further work by Gospodarowicz as reported in 1974 described a more defined isolation of proteins from cow brain extract which, when tested in a bioassay that caused fibroblasts to proliferate, led these investigators to apply the name "fibroblast ...
Fibroblast growth factor receptor 1 (FGFR-1), also known as basic fibroblast growth factor receptor 1, fms-related tyrosine kinase-2 / Pfeiffer syndrome, and CD331, is a receptor tyrosine kinase whose ligands are specific members of the fibroblast growth factor family.
Fibroblast growth factor 21 (FGF-21) is a protein that in mammals is encoded by the FGF21 gene. [ 5 ] [ 6 ] The protein encoded by this gene is a member of the fibroblast growth factor (FGF) family and specifically a member of the endocrine subfamily which includes FGF23 and FGF15/19.
Growth factor is sometimes used interchangeably among scientists with the term cytokine. [3] Historically, cytokines were associated with hematopoietic (blood and lymph forming) cells and immune system cells (e.g., lymphocytes and tissue cells from spleen, thymus, and lymph nodes).
The klotho protein is a novel β-glucuronidase (EC number 3.2.1.31) capable of hydrolyzing steroid β-glucuronides. Genetic variants in KLOTHO have been associated with human aging, [22] and klotho protein has been shown to be a circulating factor detectable in serum that declines with age. [23]
