Target Background
Growth/differentiation factor 15 (GDF-15) is a divergent member of the TGF-β superfamily of proteins (aliases: MIC-1, NAG-1, pTGFB, PDF and PLAB). Mature GDF-15 is released as a homodimer where each dimer is 25 kDa. The expression of GDF-15 is most prominent in the placenta, followed by the prostrate. Outside of the reproductive organs, it shows low constitutive expression, however, expression can be induced by stress. Cell types that produce GDF-15 include, cardiomyocytes, adipocytes, macrophages, endothelial cells and vascular smooth muscle cells. As a stress-induced cytokine, it is regulated by inflammation and stress-related proteins. The effects of GDF-15 are seen during tissue injury, metabolic conditions, pregnancy (immune tolerance) and various cancers.
