PROBLEM TO BE SOLVED: To provide a method for producing a cDNA tag for the identification of an expression gene and provide a method for analyzing the expression of the gene. SOLUTION: The cDNA tag for the identification of an expression gene is produced by preparing one kind of type II restriction enzyme and three kinds of type IIS restriction enzymes and combining a linker X containing the recognition sequences of the 1st and the 2nd enzymes with a linker Y containing the recognition sequence of the 3rd enzyme by using the three kinds of type IIS restriction enzymes. The cDNA tag is used as it is or converted to a linked product by a linking procedure, etc., to efficiently analyze the expression gene. COPYRIGHT: (C)2004,JPO
摘要:
A method is disclosed for rapid molecular profiling of tissue or other cellular specimens by placing a donor specimen in an assigned location in a recipient array, providing copies of the array, and performing a different biological analysis of each copy. The results of the different biological analyses are compared to determine if there are correlations between the results of the different biological analyses at each assigned location. In some embodiments, the specimens may be tissue specimens from different tumors, which are subjected to multiple parallel molecular (including genetic and immunological) analyses. The results of the parallel analyses are then used to detect common molecular characteristics of the genetic disorder type, which can subsequently be used in the diagnosis or treatment of the disease. The biological characteristics of the tissue can be correlated with clinical or other information, to detect characteristics associated with the tissue, such as susceptibility or resistance to particular types of drug treatment. Other examples of suitable tissues which can be placed in the matrix include tissue from transgenic or model organisms, or cellular suspensions (such as cytological preparations or specimens of liquid malignancies or cell lines).

PROBLEM TO BE SOLVED: To provide a method for producing a single strand gene tag group reflective of a kind and a ratio of quantity of a base sequence group at the mRNA 5' terminal extracted from a eukaryotic cell, to provide a method for measuring an expression level of a gene in the eukaryotic cell including a process for hybridizing a solid phase on which a DNA or a RNA containing a transcription starting site is immobilized with the single strand gene tag group, and to provide a method for preparing a gene expression profile by integrating obtained information on gene expression. SOLUTION: This single strand gene tag group reflective of the kind and the ratio of the quantity of the base sequence at the mRNA 5' terminal is produced by combining a method disclosed in a 5'SAGE method with a procedure for forming a double-stranded DNA into a single strand. Thus, it is found that the single strand gene tag group is effective for recognizing expression of a gene which targets an expression starting site, as a result of conducting hybridization with a DNA chip by using the tag group as a sample. Further, utilization of the single strand gene tag group makes it possible to conduct comprehensive expression analysis of a gene which targets various transcription starting sites.

PROBLEM TO BE SOLVED: To provide a method for rapid molecular profiling of tissue or other cellular specimens by placing a donor specimen in an assigned location in a recipient array, providing copies of the array, and performing a biological analysis different in each copy. SOLUTION: There are provided a method for rapidly and accurately detecting with high resolution the change of the copy number of the gene applicable as a maker of various genetic disorders such as cancer and trisomy by combining two arrays of much different type, a method of detecting specific "target" region (nucleic acid sequence) on a genome, corresponding to a specific genetic disorder, and a method for screening and/or diagnosing specific genetic disorders by using a probe. A composition interacting with genomic target region to treat the genetic disorders and a method for treating genetic disorders by using the composition are also provided. COPYRIGHT: (C)2010,JPO&INPIT
