DcR3/TNFRSF6B in Human Stomach Cancer Tissue. DcR3/TNFRSF6B was detected in immersion fixed paraffin-embedded sections of human stomach cancer using 10 µg/mL Goat Anti-Human DcR3/TNFRSF6B Antigen Affinity-purified Polyclonal Antibody (Catalog # AF142) overnight at 4 °C. Before incubation with the primary antibody tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained with the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific labeling was localized to the membrane of epithelial cells in gastric glands. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.
DcR3/TNFRSF6B Inhibition of Fas Ligand/TNFSF6-induced Apoptosis and Neutralization by Human DcR3/TNFRSF6B Antibody. In the presence of a cross-linking antibody, Mouse polyHistidine Monoclonal Antibody (10 µg/mL, Catalog # MAB050), Recombinant Human DcR3/TNFRSF6B Fc Chimera (Catalog # 142-DC) inhibits Recombinant Human Fas Ligand/TNFSF6 (Catalog # 126-FL) induced apoptosis in the Jurkat human acute T cell leukemia cell line in a dose-dependent manner (orange line). Under these conditions, inhibition of Recombinant Human Fas Ligand/TNFSF6 (2 ng/mL) activity elicited by Recombinant Human DcR3/TNFRSF6B Fc Chimera (50 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human DcR3/TNFRSF6B Antigen Affinity-purified Polyclonal Antibody (Catalog # AF142). The ND50 is typically 0.1-0.5 µg/mL.

Human decoy receptor 3 (DcR3), also called TNFRSF6B, TR6, and M68, is a member of the TNF receptor superfamily. The cDNA of DcR3 encodes a 300 amino acid (aa) polypeptide with a putative 23 aa signal peptide. Like osteoprotegerin (OPG), DcR3 lacks a transmembrane sequence and is a secreted protein. DcR3 shares sequence identity with OPG (31%), TNF RII (29%), and Fas (17%). It was found to be expressed in a variety of different tissues and at high levels in many malignant tumors. Among TNF family members, DcR3 was shown to bind with Fas ligand (FasL) and LIGHT and inhibit FasL- and LIGHT-induced apoptosis. Thus, in addition to DcR1, DcR2, and OPG, DcR3 is another TNFR family molecule which modulates ligands that induce apoptosis. Over-expression of DcR3 might be a mechanism by which certain tumors escape immune-cytotoxic attack.
