Developmental regulation of Na+/myo-inositol cotransporter gene expression
Molecular Brain Research, 1997myo-Inositol plays a role in many important aspects of cellular regulation including membrane structure, signal transduction and osmoregulation. It is taken up into the cells by the Na+ / myo-inositol cotransporter (SMIT). We investigated developmental changes in the expression of SMIT mRNA and protein in the rat.

Developmental, circadian and light regulation of wheat ferredoxin gene expression
Plant Molecular Biology, 1995A genomic clone encoding the precursor of wheat leaf ferredoxin has been isolated and characterised. The uninterrupted PetF gene encodes a polypeptide of 143 amino acid residues, consisting of an N-terminal presequence of 46 amino acid residues and a mature polypeptide of 97 amino acid residues.

Developmental regulation of expression of the malate synthase gene in transgenic plants
Plant Molecular Biology, 1990The cucumber malate synthase (MS) gene, including 1856 bp of 5' non-transcribed sequence, has been transferred into Petunia (Mitchell) and Nicotiana plumbaginifolia plants using an Agrobacterium binary vector. The transferred gene is found in variable copy number in different transformants, and is stably transmitted in each case as a single Mendelian ...

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

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

A Novel Gene Family with a Developmentally Regulated Expression in Xenopus laevis
Biochemical and Biophysical Research Communications, 2000We have isolated a new maternal gene called 4G2. 4G2 cDNA encodes a predicted protein of 501 amino acids, and its apparent molecular mass of 61 kDa was determined by SDS-PAGE of 4G2 recombinant protein expressed in E. coli or in vitro translated in rabbit reticulocyte lysate.

Gene expression in the human placental trophoblast: A model for developmental gene regulation
Placenta, 1992Gene expression in the human placental trophoblast is subject to both developmental and hormonal influences. Many gene products are synthesized by much higher levels in the syncytiotrophoblast than in the cytotrophoblast, and this expression appears to be influenced by hormones.

Rat lung lectin gene expression is regulated developmentally and by dexamethasone
American Journal of Physiology-Cell Physiology, 1989The cell-agglutinating activity of soluble beta-galactoside-binding proteins (lectins) is developmentally regulated in several mammalian organs. Little is known of the alterations in gene expression that underlie this developmental regulation.

Developmental regulation of leptin gene expression in rat brain and pituitary
Molecular and Cellular Endocrinology, 2001We have previously reported the expression of leptin mRNA and protein in adult rat brain and pituitary gland. We report here the presence of leptin and leptin receptor mRNA in neonatal female rat brain and pituitary using RT-PCR as well as leptin and leptin receptor immunoreactivity in neonatal rat brain. In addition, we describe age-related changes in

Developmental regulation for collagen II gene expression in transgenic mice
Teratology, 1991AbstractIn order to evaluate the involvement of the type II collagen regulatory sequences in development, we have injected a construct containing a toxin gene under the control of the rat type II collagen promoter and enhancer. The construct, pDAS10‐DTA, contained the diphtheria toxin A chain gene under the control of type II collagen sequences which ...
