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.

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

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

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

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.

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.

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
