Developmental regulation of yolk protein gene expression in Anastrepha suspensa
Archives of Insect Biochemistry and Physiology, 1997AbstractA partial cDNA clone for the 48,000 dalton yolk polypeptide gene from Anastrepha suspensa was isolated from a cDNA expression library using a yolk polypeptide antibody probe and hybridization to the Drosophila melanogaster yolk protein 1 gene.

Ascidian Actin Genes: Developmental Regulation of Gene Expression and Molecular Evolution
Zoological Science, 1997Actin is a ubiquitous protein in eukaryotic cells and plays an important role in cell structure, cell motility, and the generation of contractile force in both muscle and nonmuscle cells. Multiple genes encoding muscle or nonmuscle actins have been isolated from several species of ascidians and their expression patterns have been investigated. Sequence

Developmentally regulated gene expression of thrombomodulin in postimplantation mouse embryos
Development, 1996ABSTRACT Embryonic lethality of thrombomodulin-deficient mice has indicated an essential role for this regulator of blood coagulation in murine development. Here, the embryonic expression pattern of thrombomodulin was defined by surveying β-galactosidase activity in a mouse strain in which the reporter gene was placed under the ...

Apolipoprotein E gene expression in astrocytes
NeuroReport, 1995Apolipoprotein E (ApoE) is involved in brain development and repair. In order to investigate the contribution of astrocytes to ApoE gene expression, we investigated ApoE mRNA levels in mouse brain and in astroglial primary cultures during postnatal development and in two different trauma models.

Expression of Developmentally Regulated Genes in Embryonal Carcinoma Cells
1991Human and mouse embryonal carcinoma (EC) cell lines are widely used for analysis of early mammalian embryogenesis and germ cell neoplasia (Martin 1980; Andrews et al. 1983b). Using monoclonal antibodies raised against EC cells it has been shown that these cells express several cell surface epitopes shared with early embryonic cells. The first stem cell

Developmental Regulation of Gene Expression during Barley Endosperm Formation
Journal of Plant Physiology, 1995Summary This paper reviews recent data from our laboratories on the early phases of endosperm development in barley. First, we provide a description of endosperm morphogenesis based on immunohistochemical studies using the confocal laser scanning microscope.

Developmental Regulation of Nuclear Gene Expression in Trypanosoma brucei
1992Publisher Summary The kinetoplastids branched very early in eukaryotic evolution and exhibit several remarkable aspects of biochemistry and molecular biology. In addition to increasing the appreciation of the range of options available in eukaryotic biochemistry, each discovery of a difference between trypanosomes and their hosts gives hope for the ...

The Developmental Regulation of Albumin and α-Fetoprotein Gene Expression
1989Publisher Summary This chapter discusses the relative merits of the basic approaches to assay tissue-specific gene expression. A comparison between the albumin- α -fetoprotein (AFP) and β-globin gene families is made in terms of the possible functions for linkage and coordinated gene activity.

Developmental Genetics, 1982
AbstractThe synthesis of histones and presence of histone mRNA sequences in embryos and larvae of the brine shrimp, Artemia, were investigated. Radiolabeling of proteins synthesized in vivo followed by electrophoretic and fluorographic analysis confirmed the prediction that histone synthesis is coordinated with the wave of DNA replication in newly ...
