PROBLEM TO BE SOLVED: To provide an inspection method capable of detecting lung small cell carcinoma of poor prognosis, a means of treating lung small cell carcinoma of poor prognosis, and a method of screening a medicine for treating lung small cell carcinoma of poor prognosis.SOLUTION: A lincRNA, HOTAIR (its cDNA has a base sequence expressed by a specified sequence) has been found to be highly expressed in lung small cell carcinoma of poor prognosis. Provided is a diagnostic method for determining whether lung small cell carcinoma of concern is lung small cell carcinoma of poor prognosis or not, in which, as the expression quantity of HOTAIR as lincRNA is higher, it is determined to be more likely that it is of poor prognosis. Further, provided is siRNA which can suppress the multiplication of lung small cell carcinoma in which HOTAIR is highly expressed.
Abstract:
PROBLEM TO BE SOLVED: To provide a new peptide which can be easily produced by a chemical synthetic method or a genetic engineering procedure and has binding capability to EpCAM (epithelial cell adhesion molecule).SOLUTION: A phage group presenting a variety of peptide sequences on phage particles is brought into contact with a solid-phased EpCAM protein. Thus, the phage particles bound to the EpCAM protein are collected and the obtained phage particles are proliferated in an Escherichia coli bacterium. Then a phage clone specifically binding to EpCAM is successfully obtained by repeating a panning operation in which these proliferated phage particles are brought into contact with the EpCAM protein again. An amino acid sequence specifically binding to EpCAM is specified by analyzing a DNA sequence of the phage clone.
Abstract:
PROBLEM TO BE SOLVED: To provide a method for selecting cultured cell strain influenced by characters of a clinical specimen, and to provide a method for selecting a gene specific to a disease from which the clinical specimen is derived. SOLUTION: Hybridization is carried out on slides obtained by preparing RNAs from 38 cell strains derived from lung cancer, 3 normal fibroblast strains, 43 clinical specimens of the lung cancer and 6 normal pulmonary tissues, labeling them with a fluorescent material, and immobilizing 7685 kinds of gene fragments thereon. Usual hierarchical clustering is applied thereto, and the whole cell strains and clinical specimens are separated to each different cluster. The gene expression profile influenced by each type of diseases is considered to be obtained by removing genes commonly highly expressed or less expressed in the cultured cell strain or the clinical specimens from the analysis, and a filtering method enabling the removal is newly considered and carried out.

Abstract:
PROBLEM TO BE SOLVED: To make it possible to observe an image reliably with simple operation.SOLUTION: A movement section scrolls a medical image on a screen. In a case where the medical image is scrolled on the screen, a display section displays the medical image in a manner that an observation reference position of a diagnosis target region of the medical image passes through a display reference position of a display region of the screen. This technique can be applied to an image processing device for processing a medical image.
Abstract:
PROBLEM TO BE SOLVED: To collect region-specific expression information characterizing each piece of biological tissue, from imaging mass spectrometry data by effectively utilizing an optical microscope image on a sample.SOLUTION: An optical microscope image of a two-dimensional measurement object region on a sample is displayed, and an analyst visually determines a difference or the like of tissues and designates a plurality of small regions (A, B, and C) regarded as the same tissue. When data processing is started, peak information (m/z and intensity) is extracted from mass spectrum data at all measurement points with respect to each of the designated small regions, and important peak information of high commonality in each region is extracted by a common peak method. When comparison among a plurality of small regions is instructed by the analyst, important peak information of these small regions is collected, and region-specific peak information (expression information) characterizing respective small regions are obtained by comparison of important peak information of different small regions using a determination method like a machine learning algorithm and are stored. The region-specific expression information has high accuracy because visual determination using the optical microscope image is incorporated in this information.

PROBLEM TO BE SOLVED: To provide a method for accurately and simply detecting and analyzing a cell in which a genetic defect occurs by using FISH.SOLUTION: A method for analyzing a cell with a genetic defect has processes of: a) preparing a cell sample containing an eukaryotic cell; b) performing an antigen-antibody reaction to a cell in the cell sample by using one type or two or more types of antibodies to molecules existing on the cell surface of the eukaryotic cell after the process (a); c) performing infiltration treatment to the cell in the cell sample after the process b; d) performing fixation treatment to the cell in the cell sample after the process b; e) performing FISH to the cell in the cell sample by using one type or two or more types of nucleic acid probes after the process d; f) analyzing fluorescence signals from the nucleic acid probes in the cell contained in the cell sample by using a three-dimensional image analysis method after the process e; and g) discriminating whether or not the cell in the cell sample is the cell with the genetic defect from results of the process b and the process f.
Abstract:
PROBLEM TO BE SOLVED: To provide a histone methylation enzyme Set7/9 inhibitor, a cancer cell growth inhibitor, and a preventive and therapeutic agent of a disease resulting from an excess of an estrogen acceptor.SOLUTION: In order to solve the problem, screening is performed by using a high-throughput HMT activity measurement method which has been uniquely developed by this inventor, and cyproheptadine is defined as an inhibitor substance of Set7/9. Furthermore, the cyproheptadine selectively inhibits the Set7/9 in in-vitro, lowers an observation level of the ERα of a breast cancer cell, and inhibits the estrogen anaclitic growth of the breast cancer cell. By this, it is found that the Set7/9 inhibitor substance can be the preventive and therapeutic agent of the disease resulting from the excess of the estrogen acceptor, thus completing this invention.
Abstract:
PROBLEM TO BE SOLVED: To improve an efficiency of a diagnosis of a doctor.SOLUTION: A lesion recognition unit 12 calculates a luminance difference feature amount as a feature amount of each image of a plurality of input medical images, and recognizes a lesion progress degree and a lesion type based on the luminance difference feature amount using a lesion progress degree recognition device 21 and a lesion type recognition device 22 having learned previously. A doctor determination unit 13 refers to a doctors' specialized field database 14 to determine a doctor in attendance handling a medical image corresponding to the lesion type. An image rearrangement unit 15 rearranges the medical images for every determined doctor in attendance in order of high score of lesion progress degree recognized by the lesion progress degree recognition device 21. An image presentation unit 16 sequentially presents the rearranged medical images. This invention can be applied to, for example, a medical image processing apparatus.
