GDF-15 人

Growth-differentiation factor-15 (GDF-15) is a stress-responsive member of the transforming growth factor-β cytokine superfamily. It is also known as PTGF-Growth-differentiation factor-15 (GDF-15) and is a stress-responsive member of the transforming growth factor-β cytokine superfamily.² It is also known as PTGF-β, TGF-PL or MIC-1β, TGF-PL or MIC-1.

Growth-differentiation factor-15 (GDF-15) has been associated in the regulation of cell survival, proliferation, and differentiation and also in the protection from ischemia/reperfusion injury. Inflammatory and apoptotic pathways are regulated in injured tissues by GDFs during disease processes.

Although it has been classified as a divergent member of the transforming growth factor-β superfamily, GDF-15 shares structural characteristics with this superfamily. It has been identified as a biomarker for human prostate cancer. Additionally, increased GDF-15 expression has been observed in breast, pancreas and colorectal cancers. Functions of this cytokine include inhibition of TNF-α production, initiation of cartilage formation, and promotion of neuronal survival.
It has been discussed to serve as a secreted biomarker for activation of the p53 pathway in human cancer.

Lyophilized from a 0.2 μm filtered solution in 30% acetonitrile, 0.1% trifluoroacetic acid containing 50 μg of bovine serum albumin per 1 μg of GDF-15.

Under reducing conditions in SDS-PAGE, each recombinant GDF-15 monomer migrates as an ~14 kDa protein.
