Abnormal Elongations of HOX Gene Clusters May Cause Cancer
Hox gene activation is crucial for normal development of most organisms. Because of its importance, in both development and disease, it is intensively studied. Up to now, molecular methods have been almost exclusively used in order to explore the underlying mechanisms in normal embryonic growth (Tarchini and Duboule, 2006; Tschopp et al., 2009). The clustering of Hox genes is of particular inte...
متن کاملPulling forces acting on Hox gene clusters cause expression collinearity.
The development of normal patterns along the primary and secondary vertebrate axes depends on the regularity of early Hox gene expression. During initial stages, these expression events form a sequential pattern of partially overlapping domains along the anteroposterior axis in coincidence with the 3' to 5' order of the genes in the Hox cluster (spatial collinearity). In addition, the genes are...

متن کاملGenomic evolution of Hox gene clusters.
The family of Hox genes, which number 4 to 48 per genome depending on the animal, control morphologies on the main body axis of nearly all metazoans. The conventional wisdom is that Hox genes are arranged in chromosomal clusters in colinear order with their expression patterns on the body axis. However, recent evidence has shown that Hox gene clusters are fragmented, reduced, or expanded in man...
متن کاملNucleosome positioning in human HOX gene clusters.
The distribution of nucleosomes along the genome is a significant aspect of chromatin structure and is thought to influence gene regulation through modulation of DNA accessibility. However, properties of nucleosome organization remain poorly understood, particularly in mammalian genomes. Toward this goal we used tiled microarrays to identify stable nucleosome positions along the HOX gene cluste...
