Abstract: A previously unrecognized level of transcriptional control by the leukemogenic transcription factors TEL, and AML1/ETO, of the interferon gamma signaling pathway has been discovered. Gene expression analysis has identified downstream targets of these leukemogenic transcription factors. The associated expression and regulation of these genes in leukemia, and methods of use thereof, are described herein.

Abstract: Methods and apparatus for classifying or predicting the classes for samples based on gene expression are described. Also described are methods and apparatus for ascertaining or discovering new, previously unknown classes based on gene expression. Methods, computer systems and apparatus for classifying or predicting whether a sample is treatment sensitive (e.g., chemosensitive) or treatment resistant (e.g., chemoresistant) are also provided. Classification occurs based on analysis of gene expression data from samples that have been subjected to one or more compounds.

Abstract: Methods and apparatus for classifying or predicting the classes for samples based on gene expression are described. Also described are methods and apparatus for ascertaining or discovering new, previously unknown classes based on gene expression.

Abstract: Methods for predicting phenotypic classes of brain tumors, such as brain tumor type or treatment outcome, for brain tumor samples based on gene expression profiles are described.

Abstract: The present invention relates to methods and apparatus for grouping or clustering gene expression patterns from a plurality of genes. The invention utilizes a Self Organizing Map to cluster the gene expression patterns into groups that exhibit similar patterns. The clustering enables one to easily analyze gene expression data from potentially thousands of genes.

Abstract: Sets of genetic markers for specific tumor classes are described, as well as methods of identifying a biological sample based on these markers. Also described are diagnostic, prognostic, and therapeutic screening uses for these markers, as well as oligonucleotide arrays comprising these markers.

Abstract: Identification of MYC target genes whose expression is either induced or repressed by c-myc induction in human fibroblasts is disclosed. Also disclosed are methods of inducing or repressing expression of MYC target genes.

Abstract: The identification of a subset of genes which function in metastasis of tumor cells is described. Also described are methods of diagnosis and therapy of metastatic conditions relating to the identified genes.
