We previously described a targeted genomic differential display method (TGDD: Broude NE, Chandra A, Smith CL. Differential display of genomic subsets containing specific interspersed repeats. Proc. Natl. Acad. Sci. USA 1997;94:4548-53). In that method, presently characterized as method I, targeting was accomplished by capturing DNA fragments containing specific a sequence by hybridization with ...

Differential display or RNA fingerprinting (6,9) is widely used to identify altered cellular gene expression at the mRNA level. We describe the differential display of RNAs synthesized from transiently transfected DNA—a technique not previously reported. Although we focus on the application of this methodology to analysis of a pool of RNAs in which cytoplasmic stability can be altered because o...

Akinetes are spore-like resting cells formed by certain filamentous cyanobacteria that have increased resistance to environmental stress. They can be found at low frequencies in dense cultures experiencing low light or phosphate limitation, but also form at high frequencies in a zwf mutant strain of Nostoc punctiforme following dark incubation in the presence of fructose. The wild-type strain i...

Differential display (DD) is a widely used method for identifying differentially expressed genes. To improve further the efficiency and reproducibility of the method, this report systematically examines four critical parameters of standard DD-PCR. Specifically, the study determined the optimal annealing temperature, elongation time, dNTP concentration, and arbitrary primer concentration. By usi...

~The first two authors contributed equally to the establishment of the method and to the results obtained. 4present address: Max-Planck-Gesellschaft, MaxDelbr~ick-Haus, 13122 Berlin-Buch, Germany. Analysis of gene expression is a central aim in most studies in molecular and cell biology. Interest in tissue-specific gene expression and, in particular, in changes in the expression patterns occurr...

UNLABELLED In this article, we combined EST information from the UniGene database and orthologous relationships from the Ensembl database to construct a ZooDDD database. The primary function of ZooDDD is to mine evolutionary conserved, highly expressed, tissue-specific orthologues in model animals. The candidate genes of interest derived from the ZooDDD database will provide biologists with a g...

Digital Extractor is a program for the high-throughput processing of data sets derived from digital differential display-based comparisons of EST libraries. These comparisons can be utilized to identify discrete subsets of genes whose expression is restricted to distinct tissue types. The program facilitates these investigations by permitting parallel annotation of genes identified as being dif...

The method of differential display developed by Liang and Pardee (10) has gained a large audience and is now the method of choice to quickly identify and isolate differentially expressed genes in several experimental systems. The method is powerful because of its inherent simplicity, and it allows the simultaneous comparison of upand down-regulated genes with small amounts of raw material. Neve...

The EphA2 receptor tyrosine kinase is overexpressed in many different types of human cancers where it functions as a powerful oncoprotein. Dramatic changes in the subcellular localization and function of EphA2 have also been linked with cancer, and in particular, unstable cancer cell-cell contacts prevent EphA2 from stably binding its ligand on the surface of adjoining cells. This change is imp...
