In Hodgkin lymphoma (HL) we recently reported that deregulated homeobox gene MSX1 mediates repression of the B-cell specific transcription factor ZHX2. In this study we investigated regulation of MSX1 in this B-cell malignancy. Accordingly, we analyzed expression and function of OTX homeobox genes which activate MSX1 transcription during embryonal development in the neural plate border region. ...

Type A1 brachydactyly in humans is a recognisable syndrome characterised by shortening of the middle phalanx of all digits with occasional fusion of the middle and terminal phalanges. The purpose of this study was to evaluate candidate genes for type A1 brachydactyly in two families with multiple affected members. Several classes of genes have been implicated in the control of distal limb devel...

The adult human endometrium rapidly cycles through stages of cell proliferation, differentiation and degeneration. Inappropriate endometrial cell differentiation is a contributing factor in diseases such as endometrial carcinoma and endometriosis. We have identified two homeobox genes that may play a role in the control of endometrial cell differentiation and development. In-situ mRNA hybridiza...

In Caenorhabditis elegans three pairs of neurons, AFD, AIY, and AIZ, play a key role in thermosensation. The LIM homeobox gene ceh-14 is expressed in the AFD thermosensory neurons. ceh-14 mutant animals display athermotactic behaviors, although the neurons are still present and differentiated. Two other LIM homeobox genes, ttx-3 and lin-11, function in the two interneurons AIY and AIZ, respecti...

Glioblastoma growth is driven by cancer cells that have stem cell properties, but molecular determinants of their tumorigenic behavior are poorly defined. In cancer, altered activity of the epigenetic modifiers Polycomb and Trithorax complexes may contribute to the neoplastic phenotype. Here, we provide the first mechanistic insights into the role of the Trithorax protein mixed lineage leukemia...

Neuronal cell fate determinants establish the identities of neurons by controlling gene expression to regulate neuronal morphology and synaptic connectivity. However, it is not understood if have postmitotic functions in synapse pattern formation. Here we identify a novel role for UNC-4 homeobox protein its corepressor UNC-37/Groucho, tiled patterning cholinergic motor Caenorhabditis elegans . ...

CUT-like homeobox 1 (CUX1) has been proven to be a key regulator in sheep hair follicle development. In our previous study, CUX1 was identified as differential expressed gene between Hu lambskin with small wave patterns (SM) and straight wool (ST); however, the exact molecular mechanism of expression obscure. As DNA methylation can regulate expression, potential association core promotor region...

We report the isolation of a new homeobox gene from Xenopus laevis genomic DNA. The homeodomain sequence is highly diverged from the prototype Antennapedia sequence, and contains a unique histidine residue in the helix that binds to DNA. The homeodomain is followed by a 65 amino acid carboxyterminal domain, the longest found to date in any vertebrate homeobox gene. We have raised specific antib...
