We describe here the identification of eight polymorphic microsatellite loci with (CA)n repeats in the Trypanosoma cruzi genome based on the affinity capture of fragments using biotinylated (CA)12 attached to streptavidin-coated magnetic beads. The presence of two peaks in PCR amplification products from individual clones confirmed that T. cruzi is diploid.(More)
RNA molecules with novel functions have revived interest in the accurate prediction of RNA three-dimensional (3D) structure and folding dynamics. However, existing methods are inefficient in automated 3D structure prediction. Here, we report a robust computational approach for rapid folding of RNA molecules. We develop a simplified RNA model for discrete(More)
Large-scale analysis of the GC-content distribution at the gene level reveals both common features and basic differences in genomes of different groups of species. Sharp changes in GC content are detected at the transcription boundaries for all species analyzed, including human, mouse, rat, chicken, fruit fly, and worm. However, two substantially distinct(More)
The polymorphism at the multitude of loci adjacent to human endogenous retrovirus long terminal repeats (LTRs) was analyzed by a technique for whole genome differential display based on the PCR suppression effect that provides selective amplification and display of genomic sequences flanking interspersed repeated elements. This strategy is simple,(More)
We have found a substantial decrease in the level of Na,K-ATPase beta 2-subunit mRNA in xenografts of human renal, lung hepatocellular carcinomas in nude mice as compared with corresponding normal tissues, as well as in the neuroblastoma cell line as compared with the neuron primary cell culture. The level of beta 1 mRNA is decreased in kidney and lung(More)
cDNAs complementary to pig kidney mRNAs coding for alpha- and beta-subunits of Na+,K+-ATPase were cloned and sequenced. Selective tryptic hydrolysis of the alpha-subunit within the membrane-bound enzyme and tryptic hydrolysis of the immobilized isolated beta-subunit were also performed. The mature alpha- and beta-subunits contain 1016 and 302 amino acid(More)
We describe a technique for the detection and localization of RNA transcripts in living cells. The method is based on fluorescent-protein complementation regulated by the interaction of a split RNA-binding protein with its corresponding RNA aptamer. In our design, the RNA-binding protein is the eukaryotic initiation factor 4A (eIF4A). eIF4A is dissected(More)
Bacteria have a complex internal organization with specific localization of many proteins and DNA, which dynamically move during the cell cycle and in response to changing environmental stimuli. Much less is known, however, about the localization and movements of RNA molecules. By modifying our previous RNA labeling system, we monitor the expression and(More)
We have developed a strategy for multiplex PCR based on PCR suppression. PCR suppression allows DNA target amplification with only one sequence-specific primer per target and a second primer that is common for all targets. Therefore, an n-plex PCR would require only n + 1 primers. We have demonstrated uniform, efficient amplification of targeted sequences(More)
The multigene family of human Na,K-ATPase is composed of 5 alpha-subunit genes, 3 of which were shown to encode the functionally active alpha 1, alpha 2 and alpha 3 isoforms of the catalytic subunits. This report describes the isolation, mapping and partial sequencing of the fourth gene (ATP1AL1) that was demonstrated here to be functionally active and(More)
