HOXA9 is one of the most abundant HOX genes
Testosterone and progesterone have been shown to regulate HOX gene
Nanog and Hox genes
each have their own distinct jobs and by inhibiting each other they work together to direct the proper balance of cell states by helping the cell avoid wrong turns and stay on course.
To visualize the expression of all 39 HOX genes
, hierarchical clustering was applied (MEV4.0, Boston, MA, USA).
The orthological assignments of these new Hox genes
were determined by phylogenetic analyses by the ML (Fig.
indicate a degree of hierarchical organization, context-sensitivity as defined in the terms of the Chomsky hierarchy (see O Nuallain 2003) and long-distance dependencies, indicating that perhaps the phenomena Shieber remarked on are present also in the genome.
Moreover, hth is also expressed in cells where Hox genes
are not expressed; for example, we showed that the Hth-YFP protein trap is expressed in the hinge and notum regions (but not the pouch) of the wing disc where no Hox genes
, including Ubx, are significantly expressed .
found that both gene expression and methylation patterns were altered, proposing that DNMT3A mutations gave rise to hypomethylation of HOX genes
Human genes called the Hox genes
have the same pattern of organization, follow the same order of gene arrangement, their expressions and functions are also in sequences as observed in Drosophila.The genes HOX A,HOX B, HOX C and HOX D are arranged on four different chromosomes 7,17,12 and 2.
