Beschreibung

Allgemeine Beschreibung

Annexin A3 (UniProt P12429; also known as 35-alpha calcimedin, Annexin III, Annexin-3, Inositol 1,2-cyclic phosphate 2-phosphohydrolase, Lipocortin III, PAP-III, Placental anticoagulant protein III) is encoded by the ANXA3 (also known as ANX3) gene (Gene ID 306) in human. Annexin A3 is a Ca2+-dependent phospholipid-binding protein shown to promote angiogenesis and rat liver regeneration. Upregulated annexin A3 expression is reported in ovarian, breast, colon, lung, gastric, gallbladder, testicular, and urothelial cancers, where it is involved in promoting tumorigenesis and resistance to chemotherapy. ANXA3 is reported to represent the most significantly upregulated gene that encodes for a secretory protein in the CD133+ liver cancer stem cell (CSC) subset. Both cellular and secretory annexin A3 play pivotal roles in promoting cancer and stem cell-like features in CD133+ liver CSCs through a dysregulated JNK pathway. Annexin A3 serum levels in hepatocellular carcinoma (HCC) patients are closely associated with aggressive clinical features. Annexin A3 neutralizing antibody is shown to cause a significant reduction in HCC tumor growth and self-renewal by effectively killing off CD133+ CSCs both in cultures in vitro and in animal xenograft in vivo.

Spezifität

This monoclonal antibody detected a single ~33 kDa target band among a panel of human hepatocellular carcinoma (HCC) cell lines. The epitope has been mapped to a 10-a.a. region within the third annexin domain (Tong, M., et al. (2015). Stem Cell Reports. 5(1):45-59).

Immunogen

Recombinant human annexin A3.

Anwendung

Research Category
Zelluläre Signaltransduktion

Detect Annexin A3 using this mouse monoclonal Anti-Annexin A3 Antibody, clone 9996-1-3M1/3L7-5, Cat. No. MABS1329, validated for use in Immunohistochemistry (Paraffin) Neutralization, and Western Blotting.

Immunohistochemistry Analysis: A 1:250 dilution from a representative lot detected Annexin A3 in human placenta tissue sections.

Western Blotting Analysis: 10 µg/mL from a representative lot detected Annexin A3 in 10 µg of human spleen tissue lysate.

Immunohistochemistry Analysis: A representative lot detected a markedly downregulated annexin A3 immunoreactivity in Huh7 xenografts from antibody-treated mice, while an upregulated annexin A3 immunoreactivity was seen in xenografts from Cisplatin-treated mice (Tong, M., et al. (2015). Stem Cell Reports. 5(1):45-59).

Neutralizing Analysis: A representative lot inhibited the proliferation of CD133-/annexin A3-positive Huh7 cells, but not the CD133-/annexin A3-negative MIHA cells. Antibody treatment further sensitized Huh7 to Cisplatin (Cat. No. 232120) antiproliferative activity (Tong, M., et al. (2015). Stem Cell Reports. 5(1):45-59).

Neutralizing Analysis: A representative lot suppressed the migration, invasion, angiogenesis induction, and hepatospheres formation of human hepatocellular carcinoma (HCC) cells (Tong, M., et al. (2015). Stem Cell Reports. 5(1):45-59).

Neutralizing Analysis: A representative lot inhibited the growth of Huh7 xenograph in mice. Residual xenografts following antibody treatment (alone or with Cisplatin), but not Cisplatin treatment alone failed to form tumor mass when serially transplanted into secondary recipients (Tong, M., et al. (2015). Stem Cell Reports. 5(1):45-59).

Western Blotting Analysis: A representative lot detected the expression of the ~33 kDa Annexin A3 among a panel of human hepatocellular carcinoma (HCC) cell lines (Tong, M., et al. (2015). Stem Cell Reports. 5(1):45-59).

Qualität

Evaluated by Western Blotting in human placenta tissue lysate.

Western Blotting Analysis: 5 µg/mL of this antibody detected Annexin A3 in 10 µg of human placenta tissue lysate.

Zielbeschreibung
