Developmental regulation of gene expression in Tetrahymena
Developmental Biology, 1986The 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 Elastin Gene Expression
Critical Reviews in Eukaryotic Gene Expression, 1997Developmental 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.

Nonrestrictive developmental regulation of microRNA gene expression
Mammalian Genome, 2006During 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, 1985In 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, 2000Given 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, 1990The 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, 1997Renal 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.

Developmental regulation of gene expression in trypanosomatid parasitic protozoa
Current Opinion in Microbiology, 2007Kinetoplastids branched early from the eukaryotic lineage and include several parasitic protozoan species. Up to several hundred kinetoplastid genes are co-transcribed into polycistronic RNAs and individual mRNAs are resolved by coupled co-transcriptional trans-splicing of a universal splice-leader RNA (SL-RNA) and 3'-end maturation processes.

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.
