Abstract: A method and system for predicting the resistance of a disease to a therapeutic agent is provided. Further provided is a method and system for designing a therapeutic treatment agent for a patient afflicted with a disease. Specifically, the methods use a trained neural network to interpret genotypic information obtained from the disease. The trained neural network is trained using a database of known or determined genotypic mutations that are correlated with phenotypic therapeutic agent resistance. The present invention also provides methods and systems for predicting the probability of a patient developing a genetic disease. A trained neural network for making such predictions is also provided.

Abstract: The instant invention involves the use of a combination of preparatory steps in conjunction with mass spectroscopy and time-of-flight detection procedures to maximize the diversity of biopolymers which are verifiable within a particular sample. The cohort of biopolymers verified within such a sample is then viewed with reference to their ability to evidence at least one particular disease state; thereby enabling a diagnostician to gain the ability to characterize either the presence or absence of said at least one disease state relative to recognition of the presence and/or the absence of said biopolymer.

Abstract: The present invention discloses a method for displaying gene expression patterns of multiple genes that change according to the experiment cases, where a first axis represents the genes and a second axis represents the experiment cases. The method comprises two steps. The first step consists of designating a segment along the second axis in the expression pattern data of the multiple genes. The second step comprises clustering the expression pattern data within the designated segment along the second axis based on a predetermined reference value, repeating clustering within the same cluster in a forward or reverse direction along the second axis while changing the reference value, and displaying the results according to a predetermined display format.
Abstract: A method for determining a matrix of expression levels corresponding to a set of biological targets (e.g., genes or gene fragments) and a set of biological samples, including obtaining a matrix of signal values corresponding to the set of biological targets; computing a vector of expression levels for a sample in the set of biological samples using the matrix of signal values; storing the vector of computed expression levels in a storage matrix; repeating the computing and storing steps for each sample in the set of biological samples; and outputting the storage matrix as the matrix of expression levels. The method, based on a linear programming formulation of the problem, works for both “promiscuous” probe array data, in which there may be multiple targets indicated by a single probe, and the “polygamous” case, in which there are multiple probes for a single target. The preferred method can also process data obtained from multiple SAGE analyses using multiple markers.

Abstract: Methods of using an addressable array of biopolymers which has been exposed to a sample, and apparatus and computer program products for use of the arrays. In one embodiment the method includes detecting signals from the exposed array to obtain a signal image of the array. The array signal image is saved in a memory. Based on the detected signals, a shape of each region in one or more sets of multiple regions on the array signal image is established. A definition of the shapes of the established regions of each set is saved in a memory. Each region of each set is processed according to a corresponding routine for that set.
Abstract: The present invention is concerned with a computer-aided method for the provision, identification and description of molecules exhibiting a desired behaviour, more particularly in the pharmaceutical sector, employing a molecular modelling step, a combinatorial library building step and a step of selecting potentially useful molecules, said method including a step whereby the candidate molecules are filtered using a dynamic filter representing constraints of conformational variations which the molecules must satisfy in order to exhibit said activity.

Abstract: A method for generating stimulus response curves (e.g., dose response curves) shows how the phenotype of one or more cells change in response to varying levels of the stimulus. Each “point” on the curve represents quantitative phenotype for cell(s) at a particular level of stimulus (e.g., dose of a therapeutic). The quantitative phenotypes are multivariate phenotypic representations of the cell(s). They include various features of the cell(s) obtained by image analysis. Such features often include basic parameters obtained from images (e.g., cell shape, nucleus area, Golgi texture) and/or biological characterizations derived from the basic parameters (e.g., cell cycle state, mitotic index, etc.). The stimulus response curves may be compared to allow classification of stimuli and identify subtle differences in related stimuli. To facilitate the comparison, it may be desirable to present the response curves in a principal component space.

Abstract: The present invention aims at providing a visual display which is useful in roughly understanding the state of groupings and changes, by comparing expression data of genes from two experiments based on expression data of one sample common to both experiments. In order to compare data of expression levels obtained from different experiments each using two types of samples, three types of expression levels are displayed in three-dimension as mediated by the data of the common sample used in both experiments. Specifically, expression level data for Samples A and B and expression level data for Samples A and C are combined and converted into single three-dimensional data and displayed as points inside a sphere. Alternatively, expression states of each gene to Samples A, B and C are mapped on a sphere with respect to a ratio between Sample A and Sample B and a ratio between Samples A and C, and displayed as distribution on the surface of the sphere.
Abstract: Relatedness between genes is quantified by constructing nonlinear models predicting gene expression. Effectiveness of the model is evaluated to provide a measurement of the relatedness of genes associated with the model. Various types of models, including full-logic or neural networks can be constructed. A graphical user interface presents results of the analysis to allow evaluation by a user. Each gene's contribution to the measurement of relatedness can be shown on a graph, and graphical representations of models used to predict gene expression can be displayed.

Abstract: A simplified strategy for sequencing large genomes has been developed. Clone-Array Pooled Shotgun Sequencing (CAPSS) is based upon pooling rows and columns of arrayed genomic clones, for shotgun library construction. Random sequences are accumulated and the data are assembled by sequential comparison of rows and columns, to resolve the sequence of clones at points of intersection. Compared to either a clone-by-clone approach or whole genome shotgun sequencing, CAPSS requires relatively few library constructions and only minimal computational power for a complete genome assembly. The strategy is suitable for sequencing large genomes for which there are no sequence-ready maps, but for which relatively high resolution STS maps and highly redundant BAC libraries are available. It is immediately applicable to the sequencing of mouse, rat, zebra fish and other important genomes, and can be managed in a cooperative fashion to take advantage of the distributed international DNA sequencing capacity.
