Indicators
The red respiratory protein of erythrocytes, consisting of approximately 3.8% heme and 96.2% globin (64.5 KD), which as oxyhemoglobin (HbO2) transports oxygen from the lungs to the tissues where the oxygen is readily released and HbO2 becomes Hb.
Indicators
A physiological progestin that is produced during glucocorticoid and steroid hormone synthesis and is increased during the third trimester of pregnancy. Hydroxyprogesterone binds to the cytoplasmic progesterone receptors in the reproductive system and subsequently activates progesterone receptor mediated gene expression.
Indicators
Along with the immunoglobulin G4 subclass (IgG4), the IgG3 subtype makes up a minor part of circulating antibodies in healthy individuals. The core hinge sequence contains approximately four times the number of amino acids as the other subclasses; allotypes of IgG3 can have up to 62 hinge residues and up to four interchain disulfide bonds. The increased hinge size for IgG3 increases the separation between the Fc (constant fragment) tail and Fab (antigen binding fragment) arms of antibodies of this subclass. This enhances the relative flexibility of the molecule, which may modulate antigen-binding capacity and immune complex formation, and may increase the affinity for binding to both Fc receptors and complement component C1q.
Indicators
Exhibiting a broad range of biological activities on T and natural killer cells, Interleukin-12 is a disulfide-bonded heterodimeric cytokine composed of a 35-kD IL12A subunit (IL-6 Superfamily) and a 40-kDa IL12B subunit (Type I Cytokine Receptor 3 Family). IL12 stimulates T-cell-independent production of IFN-gamma by PBMCs, enhances NK cell lytic activity, acts as a growth factor for T- and NK-cells, and is important for Th1 and Th2 cell differentiation. Lymphocyte responses to IL12 require NOS2A and are mediated by STAT4 activator of transcription. (NCI)
Indicators
Interleukin-8 (99 aa, ~11 kDa) is encoded by the human CXCL8 gene. This protein is involved in chemotaxis and neutrophil activation.
Indicators
This gene plays a role in signal transduction and non-receptor tyrosine protein kinase activity.
Indicators
Lactotransferrin (710 aa, ~78 kDa) is encoded by the human LTF gene. This protein is involved in the mediation of both proteolysis and iron transport.
Indicators
Lipoprotein lipase (475 aa, ~53 kDa) is encoded by the human LPL gene. This protein is involved in the metabolism of triglycerides.
Indicators
An element with atomic symbol Li, atomic number 3, and atomic weight 6.941.
Indicators
A water-soluble vitamin belonging to the vitamin B family, which occurs in many animal and plant tissues, with antihyperlipidemic activity. Niacin is converted to its active form niacinamide, which is a component of the coenzymes nicotinamide adenine dinucleotide (NAD) and its phosphate form, NADP. These coenzymes play an important role in tissue respiration and in glycogen, lipid, amino acid, protein, and purine metabolism. Although the exact mechanism of action by which niacin lowers cholesterol is not fully understood, it may act by inhibiting the synthesis of very low density lipoproteins (VLDL), inhibiting the release of free fatty acids from adipose tissue, increasing lipoprotein lipase activity, and reducing the hepatic synthesis of VLDL-C and LDL-C.
Indicators
This gene plays a role in both intercellular signaling and cell fate determination.
Indicators
This gene plays a role in neuronal development and cellular differentiation. Mutations in the gene are associated with medulloblastomas, secretory breast carcinomas and other cancers.
