Anti-Recombinant HOXB13, clone A632

HOXB13 is a member of the HOXB cluster which, along with the HOXA, HOXC, and HOXD clusters, governs embryonic patterning along the cranio-caudal axis. HOXB13 plays a key role in the development of the ventral prostate, where it is expressed highly from the embryonic stage through adulthood. Research studies have shown that both overexpression and RNA interference can inhibit the growth of prostate cancer cells. HOXB13 can function as a tumor suppressor by negatively regulating growth through repression of TCF4 and androgen receptor (AR) signaling. However, HOXB13 has also been shown to be overexpressed in more invasive prostate cancers, breast and ovarian cancers, and hepatocellular carcinomas. A common germline mutation G84E in the HOXB13 protein has recently been found to be associated with significant increased risk of prostate cancer. Currently, HOXB13 is being evaluated as a marker for metastatic lesions of prostate origin.
