摘要:
The invention provides molecular markers that are associated with responsiveness of a cancer patient to a chemotherapy treatment, and methods and computer systems for determining such responsiveness based on measurements of these molecular markers. The present invention also provides methods and compositions for enhancing the efficacy of chemotherapies in patients by modulating the expression or activity of genes encoding these molecular markers and/or their encoded proteins.
摘要:
In one aspect, methods, markers, and expression signatures are disclosed for assessing the degree to which a cell sample has epithelial cell-like properties or mesenchymal cell-like properties. In another aspect, methods are provided for predicting cancer patient prognosis based on whether the cancer is classified as having a high or low EMT Signature Score.

摘要:
Methods, biomarkers, and expression signatures are disclosed for assessing the regulation status of Wnt/β-catenin signaling pathway in a cell sample or subject. More specifically, several aspects of the invention provide a set of genes which can be used as biomarkers and gene signatures for evaluating Wnt/β-catenin pathway deregulation status in a sample; classifying a cell sample as having a deregulated or regulated Wnt/β-catenin signaling pathway; determining whether an agent modulates the Wnt/β-catenin signaling pathway in sample; predicting response of a subject to an agent that modulates the Wnt/β-catenin signaling pathway; assigning treatment to a subject; and evaluating the pharmacodynamic effects of therapies designed to regulate Wnt/β-catenin pathway signaling.
摘要:
In one aspect, the present invention provides methods for determining whether an agent (e.g., candidate drug) possesses a biological activity. In another aspect, the present invention provides populations of nucleic acid molecules useful in the practice of the present invention as probes for measuring the level of expression of populations of genes.
摘要:
The present invention provides methods for utilizing the changes of hybridization levels in time during approach to equilibrium duplex formation for identifying specific hybridization to polynucleotide probes. In the invention, the changes of hybridization levels at one or more polynucleotide probes by a sample comprising a plurality of nucleic acid molecules having different sequences are monitored during their progress towards equilibrium and the continuing increase of hybridization signals beyond cross-hybridization is used as an indication of specific binding. The invention also provides methods of comparing specificities of different polynucleotides probes. The invention further provides methods for ranking and selecting polynucleotide probes that are specific to particular nucleic acids and methods for enhancing the detection of nucleic acids. The invention further provides methods for determining the orientation of nucleotide sequences.
摘要:
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.
摘要:
A method for fluorophore bias removal in microarray experiments in which the fluorophores used in microarray experiment pairs are reversed. Further, a method for calculating the individual errors associated with each measurement made in nominally repeated microarray experiments. This error measurement is optionally coupled with rank based methods in order to determine a probability that a cellular constituent is up or down regulated in response to a perturbation. Finally, a method for determining the confidence in the weighted average of the expression level of a cellular constituent in nominally repeated microarray experiments.
摘要:
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.
摘要:
The invention provides molecular markers that are associated with the progression of chronic myeloid leukemia (CML), and methods and computer systems for monitoring the progression of CML in a patient based on measurements of these molecular markers. The present invention also provides CML target genes, and methods and compositions for treating CML patients by modulating the expression or activity of these CML target genes and/or their encoded proteins. The invention also provides genes that are associated with resistance to imatinib mesylate (Gleevec™) treatment in CML patients, and methods and compositions for determining the responsiveness of a CML patient to imatinib mesylate treatment based on measurements of these genes and/or their encoded proteins. The invention also provides methods and compositions for enhancing the effect of Gleevec™ by modulating the expression or activity of these genes and/or their encoded proteins.
