Description

General description

MTDH (metadherin) is a transmembrane protein, which spans the membrane once, and has a molecular weight of 64kDa. It is also called astrocyte elevated gene-1 (AEG-1) and lysine-rich CEACAM1 coisolated (LYRIC). It was initially isolated from primary human fetal astrocytes, as a transcript induced by human immunodeficiency virus (HIV)-1. This gene is localized to human chromosome 8q22.1, and is expressed in human brain, with higher expression in neurons as compared to glial cells. This gene has 12 exons and 11 introns.

Immunogen

Protein LYRIC recombinant protein epitope signature tag (PrEST)

Application

Anti-MTDH antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

Biochem/physiol Actions

MTDH (metadherin) is highly expressed in multiple cancers such as, esophageal squamous cell carcinoma, hepatocellular carcinoma (HCC), breast, gastric, renal, prostate, colorectal cancer, non-small cell lung cancer, and glioma. It promotes angiogenesis, autophagy, tumor invasion and metastasis. It is responsible for resistance to chemotherapy and tamoxifen, and its up-regulation in invasive breast cancer is related to poor prognosis. In HER2⁺ breast cancer, it is responsible for resistance to trastuzumab. It chromosomal location is a susceptibility locus to migraine, and thus, this gene might be associated to migraine. It is up-regulated in astrocytomas, and higher the expression level, higher the grade of astrocytoma. Thus, this protein has potential as diagnostic and prognostic marker for astrocytomas. It is essential for the tumorigenesis of hepatocellular carcinoma (HCC), via the activation of NF-κB.

Features and Benefits

Prestige Antibodies^® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies^® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:

• IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
• Protein array of 364 human recombinant protein fragments.
