Abstract: This invention provides methods employing prefoldin-4 (PFDN-4) nucleic acid and polypeptide sequences to detect cancer or a propensity to develop cancer, to monitor the efficacy of a cancer treatment, and/or for prognostic applications. Further, the invention provides methods of identifying inhibitors of PfDN-4 and methods of treating cancer by inhibiting the expression and/or activity of PFDN-4.

Abstract: The present invention provides methods of determining relative copy number of target nucleic acids and precise mapping of chromosomal abnormalities associated with disease. The methods of the invention use target nucleic acids immobilized on a solid surface, to which a sample comprising two sets of differentially labeled nucleic acids are hybridized. The hybridization of the labeled nucleic acids to the solid surface is then detected using standard techniques.

Abstract: This invention provides methods, reagents and kits for treating cancer in a patient or subject, e.g., a human. Accordingly, the present methods can be used to monitor the efficacy of a cancer treatment and to treat cancer, e.g., by inhibiting the expression and/or activity of ZNF217 in a neoplastic cell.

Abstract: Disclosed are new methods comprising the use of in situ hybridization to detect abnormal nucleic acid sequence copy numbers in one or more genomes wherein repetitive sequences that bind to multiple loci in a reference chromosome spread are either substantially removed and/or their hybridization signals suppressed. The invention termed Comparative Genomic Hybridization (CGH) provides for methods of determining the relative number of copies of nucleic acid sequences in one or more subject genomes or portions thereof (for example, a tumor cell) as a function of the location of those sequences in a reference genome (for example, a normal human genome). The intensity(ies) of the signals from each labeled subject nucleic acid and/or the differences in the ratios between different signals from the labeled subject nucleic acid sequences are compared to determine the relative copy numbers of the nucleic acid sequences in the one or more subject genomes as a function of position along the reference chromosome spread.

Abstract: The present invention relates to cDNA sequences from a region of amplification on chromosome 20 associated with disease. The sequences can be used in hybridization methods for the identification of chromosomal abnormalities associated with various diseases. The sequences can also be used for treatment of diseases.

Abstract: The invention provides methods and devices for detecting the presence of one or more target analytes in a sample employing a channel having affixed therein one or more binding partners for each target analyte. Assays are carried out by transporting the sample through the channel to each successive binding partner so that target analyte present in said sample binds to the corresponding binding partner. The sample is then transported beyond the binding partner(s), followed by detection of any target analyte bound to each binding partner. In one embodiment, binding efficiency is increased by the use of segmented transport, wherein a first bolus or bubble of a fluid that is immiscible with the sample precedes the sample during transport and a second bolus or bubble of a fluid that is immiscible with the sample follows the sample. Many configurations are possible for the device of the invention.

Abstract: The present invention provides a method of detecting nucleotide sequence differences between two nucleic acid samples. The method employs a comparative genomic hybridization (CGH) technique to analyze the sequence differences between the samples. This method permits the identification of small sequence differences (e.g., sequence divergence of 1% or less) in nucleic acid samples of high complexity (e.g., an entire genome).

Abstract: The invention relates generally to the field of cytogenetics, and more particularly to methods for identifying and classifying chromosomes.

Abstract: The invention relates to the fabrication and use of biosensors comprising a plurality of optical fibers each fiber having attached to its “sensor end” biological “binding partners” (molecules that specifically bind other molecules to form a binding complex such as antibody-antigen, lectin-carbohydrate, nucleic acid-nucleic acid, biotin-avidin, etc.). The biosensor preferably bears two or more different species of biological binding partner. The sensor is fabricated by providing a plurality of groups of optical fibers. Each group is treated as a batch to attach a different species of biological binding partner to the sensor ends of the fibers comprising that bundle. Each fiber, or group of fibers within a bundle, may be uniquely identified so that the fibers, or group of fibers, when later combined in an array of different fibers, can be discretely addressed. Fibers or groups of fibers are then selected and discretely separated from different bundles.
