European Journal of Medical Research Numerous studies have been undertaken to examine the differences in HOX gene expression between normal and neoplastic tissue, but the functional relationship with the malignant phenotype has remained elusive as reviewed by Abate-Shen.29 Some investigators have explored the postulate that Hox genes expressed during embryogenesis but down-regulated during adult life are re-expressed in neoplasia-the so called oncology recapitulates ontology hypothesis.

Homeotic gene - Wikipedia MeSH Sci. . Rearrangements involving MLL and its 39 partner genes identified to date, are associated with approximately 5% of patients suffering from AML and 22% of those with acute lymphoblastic leukaemia (ALL).26 To investigate the t[(11;19)(p22;q23)] translocation which gives rise to the MLL-ENL fusion protein, commonly found in infant acute leukaemias of both myeloid and lymphoid lineage, Horton et al, established a tetracycline-regulable system of MLL-ENL expression in primary haematopoietic cells.27 Utilising a real-time quantitative PCR system 28 they were able to measure the expression of all 39 murine Hox genes and showed for the first time that reduced Hox gene expression is specific to loss of MLL-ENL and is not a consequence of differentiation. Horton SJ, Grier DG, McGonigle GJ, Thompson A, Morrow M, De Silva I, Moulding DA, Kioussis D, Lappin TR, Brady HJ, Williams O. the phenotype of the python hindlimb resembles that of mouse embryos with loss-of-function . The structures of non-Hox homeobox genes are more variable, frequently having the homeobox bridging an exon splicing site. Exp Cell Res 293(1):144153, Gendronneau G et al (2012) The loss of Hoxa5 function causes estrous acyclicity and ovarian epithelial inclusion cysts. Functional demarcation of active and silent chromatin domains in human HOX loci by noncoding RNAs. Chromosomal translocations involving the MLL gene, the human homologue of the Drosophila gene trithorax, create fusion genes which exhibit gain of function and are associated with aggressive leukaemias in both adults and children. The differential expression of HOX genes in various solid tumors thus provides an opportunity to advance our understanding of cancer development and to develop new therapeutic agents.

PubMed The specific regional functions of individual Hox genes largely reflect their restricted expression patterns, the disruption of which can lead to developmental defects and disease.

Altered patterns of HOX gene expression have also been demonstrated in several acquired disorders including emphysema, primary pulmonary hypertension and lung carcinomas.21,22, Murine models in which Hox gene expression has either been reduced or deleted provide strong evidence for the role of these genes in structural development of the respiratory system and regulation of pulmonary surfactant production.
