Hox genes, a subset of homeobox genes, are a group of related genes that specify regions of the body plan of an embryo along the head-tail axis of animals. Hox proteins encode and specify the characteristics of 'position', ensuring that the correct structures form in the correct places of the body.
Hox genes are the most commonly known subset of homeobox genes. They are essential metazoan genes that determine the identity of embryonic regions along the anterior-posterior axis. [ 27 ] The first vertebrate Hox gene was isolated in Xenopus by Edward De Robertis and colleagues in 1984. [ 28 ]
Hox genes are a subset of the homeobox genes. The Hox genes are often conserved across species, so some of the Hox genes of Drosophila are homologous to those in humans. In general, Hox genes play a role of regulating expression of genes as well as aiding in development and assignment of specific structures during embryonic growth.
The homeobox gene clusters studied by Ed Lewis were named the Hox genes, although many more homeobox genes are encoded by animal genomes than those in the Hox gene clusters. The homeotic-function of certain proteins was first postulated to be that of a "selector" as proposed by Antonio Garcia-Bellido. [11]
Homeobox protein Hox-A9 is a protein that in humans is encoded by the HOXA9 gene. [5] [6] In vertebrates, the genes encoding the class of transcription factors called homeobox genes are found in clusters named A, B, C, and D on four separate chromosomes. Expression of these proteins is spatially and temporally regulated during embryonic ...
Homeobox protein Hox-C6 is a protein that in humans is encoded by the HOXC6 gene. [5] [6] [7] Hox-C6 expression is highest in the fallopian tube and ovary. [8]HoxC6 has been highly expressed in many types of cancers including prostate, breast, and esophageal squamous cell cancer.
This gene and other HOXB genes form a gene cluster on chromosome 17 in the 17q21.32 region. [6] Men who inherit a rare (<0.1% in a selected group of patients without clinical signs of prostate cancer ) genetic variant in HOXB13 (G84E or rs138213197) have a 10-20-fold increased risk of prostate cancer.
