Two novel mouse genes, Ebf2 and Ebf3, have been identified which show high similarity to the rodent Ebf/Olf-1 and the Drosophila collier genes. The strong conservation of the protein regions corresponding to the DNA binding and dimerisation domains previously defined in Ebf strongly suggests that Ebf2 and Ebf3 also constitute DNA sequence-specific(More)
The Drosophila lymph gland (LG) is a model system for studying hematopoiesis and blood cell homeostasis. Here, we investigated the patterns of division and differentiation of pro-hemocytes in normal developmental conditions and response to wasp parasitism, by combining lineage analyses and molecular markers for each of the three hemocyte types. Our results(More)
We present here the description of genes coding for molluscan hemocyanins. Two distantly related mollusks, Haliotis tuberculata and Octopus dofleini, were studied. The typical architecture of a molluscan hemocyanin subunit, which is a string of seven or eight globular functional units (FUs, designated a to h, about 50 kDa each), is reflected by the gene(More)
The transcriptional organization of the Drosophila melanogaster serendipity (sry) locus (previously designated EH8) has been investigated by DNA sequencing, S1 nuclease mapping, and primer extension analysis. The data indicate that the five different (and partially overlapping) sry messenger RNAs detectable in early embryos are initiated at three separate(More)
The Drosophila serendipity alpha (sry alpha) gene is specifically transcribed at the blastoderm stage, from nuclear cycle 11 to the onset of gastrulation, in all somatic nuclei. This pattern of transcription and a zygotic cellularization defect observed in embryos homozygous for Df(3R)X3F, a deficiency covering the sry locus, suggest that sry alpha plays a(More)
The recent determination and annotation of the entire euchromatic sequence of the Drosophila melanogaster genome predicted the existence of about 13600 different genes (Science 287 (2000) 2185; http://www.fruitfly.org/annot/index.html). In parallel, the Berkeley Drosophila Genome Project (BDGP) has undertaken systematic P-insertion screens, to isolate new(More)
In Drosophila, as in mammals, epidermal differentiation is controlled by signalling cascades that include Wnt proteins and the ovo/shavenbaby (svb) family of zinc-finger transcription factors. Ovo/svb is a complex gene with two genetic functions corresponding to separate control regions: ovo is required for female germline development and svb for epidermal(More)
INTRODUCTION Extrapleural pneumonectomy (EPP) and adjuvant high-dose radiation therapy (RT) are associated with a median survival of 3 years in early-stage malignant pleural mesothelioma (MPM) but of less than 1 year in locally advanced disease. Although local control after EPP and RT is excellent, most patients die of distant metastases. We designed this(More)
Drosophila haemocytes (blood cells) originate from a specialized haematopoietic organ-the lymph gland. Larval haematopoietic progenitors (prohaemocytes) give rise to three types of circulating haemocytes: plasmatocytes, crystal cells and lamellocytes. Lamellocytes, which are devoted to encapsulation of large foreign bodies, only differentiate in response to(More)
During Drosophila embryogenesis, mesodermal cells are recruited to form a stereotyped pattern of about 30 different larval muscles per hemisegment. The formation of this pattern is initiated by the specification of a special class of myoblasts, called founder cells, that are uniquely able to fuse with neighbouring myoblasts. We report here the role of the(More)
