The present invention relates to means for the detection and characterization of nucleic acid sequences, as well as variations in nucleic acid sequences. The present invention also relates to methods for forming a nucleic acid cleavage structure on a target sequence and cleaving the nucleic acid cleavage structure in a site-specific manner. The structure-specific nuclease activity of a variety of enzymes is used to cleave the target-dependent cleavage structure, thereby indicating the presence o...

The present invention is directed to the use of human BC200 RNA in both the diagnosis and prognosis of carcinomas to determine the presence of a carcinoma and tumor grade, and also to predict the likelihood that a carcinoma will progress to an invasive carcinoma.

The present invention discloses a method for rapid assessment of lung cancer therapy efficacy in a few days instead of weeks by conventional imaging methods. This method can also be used to detect relapse of the cancer and to improve the current TNM cancer staging method for more accurate prognosis. The rapid assessment of therapy efficacy is based on detecting circulating cancer cells in body fluid with high positive detection rate. The high positive detection rate is achieved by using qPCR amp...

MH15 (Hn1L) is identified as an oncogene. Methods and compositions for detecting and diagnosing cancer in patients are provided, by determining the level of MH15 expression in biological samples. Also provided are methods for screening for inhibitors and moderators of MH15 expression and activity, as well as compositions comprising compounds and molecules that inhibit or moderate MH15 expression or activity, thereby treating cancer, in vivo.

Methods identifying prostate cancer, methods for prognosing and diagnosing prostate cancer, methods for identifying a compound that modulates prostate cancer development, methods for determining the efficacy of a prostate cancer therapy, and oligonucleotide microarrays containing probes for genes involved in prostate cancer development are described.

Twenty-three markers are provided which are epigenetically silenced in ovarian cancers. The markers can be used diagnostically, prognostically, therapeutically, and for selecting treatments that are well tailored for an individual patient. Restoration of expression of silenced genes can be useful therapeutically, for example, if the silenced gene is a tumor-suppressor gene. Restoration can be accomplished by supplying non-methylated copies of the silenced genes or polynucleotides encoding their ...

There is provided a substrate for lysing cells and purifying nucleic acid having a matrix and a coating and an integrity maintainer for maintaining the purified nucleic acid. Also provided is a method of purifying nucleic acid by applying a nucleic acid sample to a substrate having an anionic detergent affixed to a matrix, the substrate physically capturing the nucleic acid, bonding the nucleic acid to a substrate and generating a signal when the nucleic acid bonds to the substrate indicating th...

It is intended to provide a means of diagnosing myocardial infarction which shows a high accuracy and a high predictability. The risk of myocardial infarction is diagnosed by a method comprising the following steps: (i) the step of analyzing 2 or more polymorphisms among 10 gene polymorphisms or 5 gene polymorphisms proved as relating to myocardial infarction; (ii) the step of determining the genotype of a nucleic acid sample based on the polymorphism data obtained in the above step; and (iii) t...

The invention provides methods and materials for the conversion of cytosine to uracil. A nucleic acid, such a gDNA, is reacted with bisulfate, such as magnesium bisulfite, in the presence of a quaternary amine catalyst. Examples of suitable quaternary amine catalysts include but are not limited to quaternary ammonium compounds, quaternary alkyl ammonium salts, quaternary alkyl ammonium halides, quaternary methyl ammonium bromide, quaternary ammonium chloride, tetraethylammonium hydroxide, tetrae...

A method for producing a mutant gene encoding a functional gene product comprising: (a) introducing one or more mutations into a gene to form a mutated gene; (b) providing the mutated gene to a host microorganism; (c) culturing the host microorganism containing the mutated gene under conditions which allow expression of the mutant gene product; and (d) selecting a host microorganism capable of producing a functional gene production from the mutated gene.
