Homeobox genes in vertebrate gastrulation

Current Opinion in Genetics & Development, 1995
The formation and anteroposterior patterning of the three definitive germ layers, ectoderm, or epiblast, is the common theme of vertebrate gastrulation. What changes from system to system is the geometry of these events and the nature of the non-epiblast transient structures implicated.

Cloning of rat homeobox genes

Biochemical Genetics, 1994
We report the isolation of nine rat cognates of mouse homeoboxes within the four Hox gene clusters and a rat homologue of mouse IPF1 homeobox, RHbox#13A. The sequences of nine cloned homeoboxes are highly similar to those of the mouse and human homeoboxes in the Hox clusters. The restriction enzyme sites and map distances between each of the homeoboxes

The role of homeobox genes in hematopoiesis

Biotherapy, 1998
Homeobox genes encode transcription factors containing a common DNA-binding motif found in virtually all animal species. Different homeobox gene families have evolved which encode homeodomains of different types or classes and thus far approximately 170 homeobox genes have been cloned. Homeoproteins are involved in the control of animal development and

Duplicated homeobox genes in Xenopus

Developmental Biology, 1989
Multiple kinds of clones and restriction fragment polymorphisms are frequently encountered when analyzing genes of the tetraploid frog Xenopus laevis. Two types of cDNA clone have been isolated for homeobox gene 2. Analysis of their corresponding genomic clones confirmed the existence of clearly distinct restriction maps; in addition the nearby ...

Homeobox genes and gut development

BioEssays, 2000
The gut of vertebrates exhibits a common anteroposterior regional differentiation. The role of homeobox genes in establishing this pattern is inferred by their sites of expression. It is suggested that the primary source of positional information is in the endoderm, which subsequently establishes a 'dialogue' with the surrounding visceral layer of the ...

Homeobox genes in Caenorhabditis elegans

Current Opinion in Genetics & Development, 1993
It is estimated that approximately 60 homeobox genes occur in the nematode Caenorhabditis elegans. These genes are required for specifying the cell fate of both precursor and terminally differentiated cells. In some cases, highly specific cell functions, such as migration pattern or synaptic connectivity, require the action of these genes.

Hemangiomas and Homeobox Gene Expression

Journal of Craniofacial Surgery, 2006
Hemangiomas are the most common benign tumor of childhood. Clinical management is limited primarily to observation. Non-surgical treatment modalities have had mixed results and with morbid side effects. Improved understanding of angiogenesis over the last two decades is helping to delineate differences between various vascular tumors.

MEIS homeobox genes in neuroblastoma

Cancer Letters, 2005
The common pediatric tumor neuroblastoma originates from primitive neural crest-derived precursor cells of the peripheral nervous system. Neuroblastoma especially affects very young children, and can already be present at birth. Its early onset and cellular origin predict the involvement of developmental control genes in neuroblastoma etiology.

A hox/hom homeobox gene in sponges

Gene, 1995
The hox/hom homeobox genes code for DNA-binding proteins that confer positional information during animal development; these genes have been found in a wide range of triploblasts and in cnidarians. We report here the identification of a hox/hom gene and two other homeobox genes in the genomes of sponges.
