The homeobox transcription factor Mtx2 is essential for epiboly, the first morphogenetic movement of gastrulation in zebrafish. Morpholino knockdown of Mtx2 results in stalling of epiboly and lysis due to yolk rupture. However, the mechanism of Mtx2 action is unknown. The role of mtx2 is surprising as most mix/bix family genes are thought to have roles in(More)
A fourth recently discovered isozyme of sn-glycerol-3-phosphate dehydrogenase (GPDH-4) in Drosophila melanogaster is shown to be a translational product of the Gpdh transcript which contains exons 1 through 7. This transcript was also found in two other Drosophila species, D. busckii and D. virilis. In contrast to D. melanogaster and D. busckii, the Gpdh(More)
Members of the Ikaros family of transcription factors are important for immune system development. Analysis of Ikaros-related genes from a range of species suggests the Ikaros family derived from a primordial gene, possibly related to the present-day protostome Hunchback genes. This duplicated before the divergence of urochordates to produce two distinct(More)
Members of the matrix metalloproteinase (MMP) family are important for the remodeling of the extracellular matrix in a number of biological processes including a variety of immune responses. Two members of the family, MMP2 and MMP9, are highly expressed in specific myeloid cell populations in which they play a role in the innate immune response. To further(More)
Considerable progress has been made in understanding the molecular basis of normal white blood cell development and its perturbation in disease through the use of clinical studies and traditional animal and cell line models. Despite this, however, many questions are still being answered and white blood cell disorders, including leukemia and lymphoma, remain(More)
Members of the Ikaros family of zinc-finger transcription factors have been shown to be critical for immune and blood cell development. However, the role of the most divergent family member, Pegasus, has remained elusive, although it shows conservation to invertebrate Hunchback proteins that influence embryonic patterning through regulation of homeodomain(More)
