Specificity / Sensitivity

HOXB9 (E7P5O) Rabbit mAb recognizes endogenous levels of total HOXB9 protein. This antibody does not cross-react with HOXA9, HOXC9, or HOXD9 proteins.

Species Reactivity:

Human, Monkey

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Val116 of human HOXB9 protein.

Background

HOXB9 is a member of the HOXB gene cluster which, along with the HOXA, HOXC, and HOXD gene clusters, governs embryonic patterning along the cranio-caudal axis (1,2). HOXB9 protein functions to regulate formation of the rib cage and contributes to development of the forelimbs (3,4). De-regulation of HOXB9 protein expression is associated with multiple types of cancer. HOXB9 expression is downregulated in pancreatic ductal adenocarcinoma and upregulated in lung adenocarcinoma, where it is associated with poor prognosis (5,6). Overexpression of HOXB9 in breast and hepatocellular carcinomas activates the epithelial-to-mesenchymal transition (EMT) through modulation of TGF-β, promoting tumor progression and metastasis (7,8). HOXB9 overexpression in gliomas increases tumorigenicity by stimulating proliferation, migration, and sphere formation (9).
