Developmental and immune regulation of gene expression in Hymenolepis diminuta

Molecular and Biochemical Parasitology, 1987
Gene expression and its regulation was studied in the rat tapeworm, Hymenolepis diminuta, during strobilization. RNAs extracted from the different developmental stages of the parasite were translated in vitro in a rabbit reticulocyte lysate system. Two-dimensional patterns of the translational products were compared with the 2-dimensional patterns ...

Developmental Regulation of Elastin Gene Expression

Critical Reviews™ in Eukaryotic Gene Expression, 1997
Developmental regulation of elastin gene expression appears to be exerted primarily at the transcriptional level. Although the elastin gene promoter possesses features of "housekeeping" genes, these characteristics do not preclude transcriptional regulation as shown with a number of other gene promoters of this class.

Developmental regulation of gene expression in Tetrahymena

Developmental Biology, 1986
The onset of gene expression in Tetrahymena thermophila during macronuclear differentiation was investigated by assay of galactokinase in conjugating deoxygalactose-resistant heterokaryons. Our results distinguish three successive states of galactokinase gene expression for cells developing a new macronucleus: stage 0, refractory to induction; stage 1,

Developmental regulation of globin gene expression

Journal of Cell Science, 1992
ABSTRACT We have used the globin family of genes in chicken to study developmental regulation of gene expression, both at the level of individual interaction of trans-acting factors with local promoters and enhancers, and at the level of chromatin structure.

Nonrestrictive developmental regulation of microRNA gene expression

Mammalian Genome, 2006
During different periods of mammalian development, global changes in gene expression occur. Developmental changes in global gene expression have been modeled as a restrictive process. To test the restriction model of global changes in gene expression, we have used embryonic stem (ES) cells as a model system for the early mammalian embryo.

Developmental regulation of T-cell receptor gene expression

Nature, 1985
In contrast to B cells or their antibody products, T lymphocytes have a dual specificity, for both the eliciting foreign antigen and for polymorphic determinants on cell surface glycoproteins encoded in the major histocompatibility complex (MHC restriction). The recent identification of T-cell receptor glycoproteins as well as the genes encoding T-cell

Developmentally regulated gene expression of Th2 cytokines in the brain

Brain Research, 2000
Given the critical role of cytokines in the regulation of an inflammatory response, we investigated whether certain cytokines are expressed in the brains of normal mice during maturation that could contribute to the immune-privileged nature of the CNS or potentially influence an immune-mediated illness such as experimental allergic encephalomyelitis ...

Developmental and Tissue-Specific Regulation of Proglucagon Gene Expression*

Endocrinology, 1990
The pattern of glucagon gene expression and the posttranslational processing of proglucagon was studied in the fetal and neonatal rat. Pancreatic immunoreactive glucagon (IRG) and glucagon-like immunoreactivity (GLI) were low in both fetal pancreas and intestine, respectively.

Zis: a developmentally regulated gene expressed in juxtaglomerular cells

American Journal of Physiology-Renal Physiology, 1997
Renal juxtaglomerular (JG) cells are specialized myoepithelioid cells located in the afferent arteriole at the entrance to the glomerulus. Their main function and distinctive feature is the synthesis and release of renin, the key hormone-enzyme of the renin-angiotensin system that regulates arterial blood pressure.
