Descriptions：Haptoglobin is a glycoprotein, which is synthesized in the liver and circulates in the blood. Haptoglobin is usually produced by liver cells, but it is also produced by other tissues, such as skin, lung and kidney. It is a positive acute phase protein, which binds to free hemoglobin and removes it from circulation to prevent kidney injury and iron loss after hemolysis. Decreased levels can be seen in hemolysis and impaired liver function. A high level is a sign of acute or chronic inflammation. Hemoglobin deficiency or hypohaptoglobinemia is caused by mutation of haptoglobin gene and/or its regulatory region. Haptoglobin is also related to diabetic nephropathy, the incidence of coronary artery disease in type 1 diabetes, Crohn's disease, inflammatory disease behavior, susceptibility to primary sclerosing cholangitis, idiopathic Parkinson's disease and the reduction of the incidence of plasmodium falciparum malaria.

Descriptions：Heparin Binding Growth Factors (HDGF) is a 27.6 kDa hepatoma-derived Growth Factors with 246 amino acid residues. HDGF is mainly expressed from mitochondria and proteasome. Functionally, it is a potent mitogen, stimulating the growth of vascular smooth muscle cells, hepatoma cells and endothelial cells, acting as a transcriptional repressor. HDGF is expressed in a variety of cancers.

Descriptions：Interleukin 12 (IL-12) is a pro-inflammatory cytokine with a molecular weight of 70 kDa composed of two subunits, IL-12 p35 (35 kDa) and IL-12 p40 (40 kDa). IL-12 p40 is induced in excess over the other subunits of IL-12 and IL-23 and can exist in a monomeric or homodimeric form.

Descriptions：GDF-3 (previously called Vgr-2) is a TGF-beta superfamily member belonging to the growth/differentiation factor family. GDF-3 is expressed in undifferentiated embryonic stem (ES) cells, white adipose tissue and the brain. The 366 amino acid (aa) mouse GDF-3 contains a 22 aa signal sequence, a 230 aa propeptide and a 114 aa mature protein that contains one potential N-glycosylation site. The mature region contains a cysteine-knot structure that is conserved throughout family members. However, it lacks the fourth cysteine which is responsible for the formation of an inter-molecular disulfide bond, so GDF-3 may exist as a non-covalent homodimer. Mature human GDF-3 shares 83%, 83% aa sequence identity with mouse and rat GDF-3. Most of GDF-3 is present as the uncleaved prepro form. The uncleaved and the mature forms both appear to have activity, but that activity may differ. All forms can oppose BMPs. In ES cells, inhibition of BMP2 signaling by GDF-3 maintains pluripotency. GDF-3 also influences early cell fate decisions; for example, deletion of mouse GDF-3 produces defects in the anterior visceral endoderm of the pre-gastrulation embryo. GDF-3 cooperates with GDF-1 in embryogenesis, and the mature protein has nodal-like activity. Although GDF family members signal through BMP receptors (ALK1, 2, 3 and 6), which activate Smads 1, 5 and 8, GDF-3 signaling through ALK4 and ALK7, which activate Smads 2 and 3, has also been reported. In adipocytes, GDF-3 is induced by a high fat diet, promoting adipogenesis and obesity.
