The present invention relates to genetic markers whose expression is correlated with breast cancer. Specifically, the invention provides sets of markers whose expression patterns can be used to differentiate clinical conditions associated with breast cancer, such as the presence or absence of the estrogen receptor ESR1, and BRCA1 and sporadic tumors, and to provide information on the likelihood of tumor distant metastases within five years of initial diagnosis. The invention relates to methods of using these markers to distinguish these conditions. The invention also relates to kits containing ready-to-use microarrays and computer software for data analysis using the statistical methods disclosed herein.

Diagnosis and prognosis of breast cancer patients

The present invention relates to genetic markers whose expression is correlated with colon cancer. In one aspect, the invention provides sets of markers whose expression can be used for classifying colon cancer patients into different prognostic categories. In another aspect, the invention provides kits containing marker sets for determining prognosis of colon cancer. In another aspect, the invention provides methods of classifying cancer patients with regard to prognosis.

Methods for diagnosis and/or prognosis of colon cancer

The present invention provides prognostic methods for conditions such as cancer, for example, breast cancer, comprising classifying an individual by a plurality of phenotypic, genotypic or clinical characteristics of the condition into a plurality of patient subsets, and analyzing the pattern of expression of prognosis-informative genes identified for that subset in a sample from the individual. The present invention also provides methods for constructing such patient subsets and of identifying prognosis-informative genesets for such subsets. The invention further provides methods of assigning a therapeutic regimen to an individual, microarrays useful for performing prognosis, kits comprising these microarrays, and computer systems and programs for implementing the methods of the invention.

Classification of breast cancer patients using a combination of clinical criteria and informative genesets

The present invention provides methods for enhanced detection of biological response patterns. In one embodiment of the invention, genes are grouped into basis genesets according to the co-regulation of their expression. Expression of individual genes within a geneset is indicated with a single gene expression value for the geneset by a projection process. The expression values of genesets, rather than the expression of individual genes, are then used as the basis for comparison and detection of biological response with greatly enhanced sensitivity. In another embodiment of the invention, biological responses are grouped according to the similarity of their biological profile. The methods of the invention have many useful applications, particularly in the fields of drug development and discovery. For example, the methods of the invention may be used to compare biological responses with greatly enhanced sensitivity. The biological responses that may be compared according to these methods include responses to single perturbations, such as a biological response to a mutation or temperature change, as well as graded perturbations such as titration with a particular drug. The methods are also useful to identify cellular constituents, particularly genes, associated with a particular type of biological response. Further, the methods may also be used to identify perturbations, such as novel drugs or mutations, which effect one or more particular genesets. The methods may still further be used to remove experimental artifacts in biological response data.

Methods for using co-regulated genesets to enhance detection and classification of gene expression patterns

The present invention relates to genetic markers whose expression is correlated with breast cancer. Specifically, the invention provides sets of markers whose expression patterns can be used to differentiate clinical conditions associated with breast cancer, such as the presence or absence of the estrogen receptor ESR1, and BRCA1 and sporadic tumors, and to provide information on the likelihood of tumor distant metastases within five years of initial diagnosis. The invention relates to methods of using these markers to distinguish these conditions. The invention also provides methods of classifying and treating patients based on prognosis. The invention also relates to kits containing ready-to-use microarrays and computer software for data analysis using the diagnostic, prognostic and statistical methods disclosed herein.

Methods of assigning treatment to breast cancer patients

The invention provides methods for removing unwanted response components (i.e., 'artifacts') from a measured biological profile comprising measurements of a plurality of cellular constituents of a cell or organism in response to a perturbation. The methods involve subtracting from the measured biological profile one or more artifact patterns, each of which comprises measurements of changes in cellular constituents as a result of deviation of one or more experimental variables, such as cell culture density and temperature, hybridization temperature, as well as concentrations of total RNA and/or hybridization reagents, from desired values.

Methods for removing artifact from biological profiles

The present invention provides methods for enhanced detection of biological response profiles. In particular, the methods of this invention allow for the detection of biological response patterns, such as gene expression patterns, in response to different drug treatments. The methods of the invention also allow the determination of a &ldquo;consensus profile&rdquo; which describes a particular class or type of biological response. In certain embodiments the consensus profile may describe the biological response of a particular group or class of drugs. In other embodiments, the consensus profile may describe an &ldquo;ideal&rdquo; biological response such as one associated with a desired therapeutic effect. The methods of the present invention also allow for the comparison of different biological responses. Thus, the methods of the invention may be used, e.g., to identify and/or study new drugs.
