Developmental regulation of globin gene expression
Journal of Cell Science, 1992ABSTRACT 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.

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.

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,

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

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.

Membrane sites regulating developmental gene expression in Dictyostelium discoideum
Cell, 1982Postaggregative gene expression in Dictyostelium discoideum requires cell contact. Polyspecific monovalent antibodies (Fab) prepared from sera raised against membranes of aggregation- and postaggregation-stage cells were used to probe the cell interactions that induce rapid postaggregative synthesis of UDP-glucose pyrophosphorylase.

Developmental Regulation of Murine Mammary Progesterone Receptor Gene Expression*
Endocrinology, 1990Previously we have shown that in normal murine mammary glands progesterone receptor (PgR) levels are modulated as a function of development and differentiation such that lactating mammary glands do not contain detectable levels of PgR as measured by steroid binding. The objective of the present study was to determine whether the lack of steroid binding
