Abstract: A plurality of oligonucleotides are caused to bind specifically to target nucleic acid which is predictive of a disease state or a biological condition within cells containing the target nucleic acid. The respective oligonucleotides, which may be functionilized or may be present in the form of oligonucleotide analogs, carry with them a plurality of synthons. Such synthons, which may be identiphores, toxiphores, or other precursors to biologically effective molecules, interact when specific binding of the respective oligonucleotides occurs at sites adjacent to each other on the target nucleic acid. The resulting interaction gives rise to the synthesis, generation or release of highly active biological molecules in situ in the cell in which the specific binding takes place. This permits the use of extraordinarily toxic molecules for use in killing cells containing the target nucleic acids. Imaging and other uses are also provided by the present invention.

Abstract: Genetic polymorphisms are identified in the human UGT1 gene that alter UGT1-dependent drug metabolism. Nucleic acids comprising the polymorphic sequences are used to screen patients for altered metabolism for UGT1 substrates, potential drug-drug interactions, and adverse/side effects, as well as diseases that result from environmental or occupational exposure to toxins. The nucleic acids are used to establish animal, cell and in vitro models for drug metabolism.

Abstract: A novel polymorphism in the human PC-1 gene is characterized, which is associated with an increased predisposition to developing insulin resistance. The polymorphism affects heterozygous and homozygous carriers of the allele. The subject nucleic acids and fragments thereof, encoded polypeptides, and antibodies specific for the polymorphic amino acid sequence are useful in determining a genetic predisposition to insulin resistance. The encoded protein is useful in drug screening for compositions that affect the activity of PC-1 and insulin receptor activity or expression.

Abstract: The present invention provides for methods of distinguishing melanocytic nevi, such as Spitz nevi, from malignant melanoma. The methods comprise contacting a nucleic acid sample from a patient with a probe which binds selectively to a target polynucleotide sequence on a chromosomal region such as 11p, which is usually amplified in Spitz nevi. The nucleic acid sample is typically from skin tumor cells located within a tumor lesion on the skin of the patient. Using another probe which binds selectively to a chromosomal region such as 1q, 6p, 7p, 9p, or 10q, which usually show altered copy number in melanoma, the method can determine that those tumor cells with no changes in copy number of 1q, 6p, 7p, 9p, or 10q, are not melanoma cells but rather Spitz nevus cells. The finding of amplifications of chromosome 11p would be an additional indication of Spitz nevus.

Abstract: The present invention is directed to methods of identifying target nucleic acid sequences which are predictive of preselected disease states or biological conditions in cells containing the nucleic acid sequence. Members of a set of mRNA molecules from a common gene, but containing different sequences and structures, are compared. The gene is predictive of the disease state or biological condition in cells containing the gene. At least one molecular interaction site from among those present in the members of the set are identified. The molecular interaction site is present in cells likely to have the disease state or biological condition. At least one nucleic acid sequence from the molecular interaction site is ascertained.

Abstract: Xylanase DNA is recovered from soil by PCR amplification using degenerate primers. Because of the complexity of the soil samples, it is likely that the recovered product will include more than one species of polynucleotide. These recovered copies may be cloned into a host organism to produce additional copies of each individual species prior to characterization by sequencing. Recovered DNA which is found to vary from known xylanases can be used in several ways to facilitate production of novel xylanases for industrial application. First, the recovered DNA, or probes corresponding to portions thereof, can be used as a probe to screen DNA libraries and recover intact xylanase genes including the unique regions of the recovered DNA. Second, the recovered DNA or polynucleotides corresponding to portions thereof, can be inserted into a known xylanase gene to produce a recombinant xylanase gene with the sequence variations of the recovered DNA.

Abstract: This invention relates to methods and nucleic acid probes for assessing characteristics of lipid metabolism in animals, and in particular to methods of predicting fat levels in meat, milk, or other fat depots of animals. Thus the invention provides a method of assessing the fat metabolism characteristics of an animal, comprising the step of testing the animal for the presence or absence of one or more markers selected from the group consisting of: a) an allele of the 5′ untranslated region of thyroglobulin; b) an allele of the DNA polymorphism CSSM34, associated with the gene encoding retinoic acid receptor gamma (RARG); and c) an allele of the DNA polymorphism ETH10, associated with 11-cis, 9-cis retinol dehydrogenase (RDH5). The invention is particularly applicable to predicting disposition of fat in muscle tissue, which produces the characteristic “marbling” of meat, and to assessment of milk fat content.

Abstract: Teeth, the hardest substance in the human body, are frequently all that remain of a mortuary population from which direct human presence can be gleaned. As such their morphology is invaluable to physical anthropologists and investigators in allied disciplines. Methods currently used for purposes of extracting DNA from dental remains—e.g. bone-milling, crushing, and sectioning—result in total destruction of the teeth. This paper introduces the Reverse-Root-Canal, a protocol by which DNA of molecular weight higher than that obtainable through traditional destructive means, can be obtained from ancient dental remains without harm to the morphologically informative crown and roots.

Abstract: Karnal bunt of wheat is caused by Tilletia indica Mitra. Recently, teliospores morphologically resembling T. indica were isolated from bunted ryegrass seeds and wheat seed washes. Previously developed PCR assays failed to differentiate T. indica from the newly discovered ryegrass pathogen, T. walkeri. The nucleotide sequence of a 2.3-kb region of mitochondrial DNA, previously amplified by PCR only from T. indica, was determined for three isolates of T. indica and for three isolates of T. walkeri. There was greater than 99% identity within either the T. indica group or the T. walkeri group of isolates, whereas there was approximately 3% divergence between isolates of these two Tilletia species. Five sets of PCR primers were made specific to T. indica, and three sets were designed specifically for T. walkeri based upon nucleotide differences within the mtDNA region.

Abstract: Methods, employing a nucleotide integrase, for cleaving single-stranded RNA substrates, single-stranded DNA substrates, and double-stranded DNA substrates at specific sites and for inserting a nucleic acid molecule into the cleaved substrate are provided.
