Abstract: The present technology relates to methods for determining whether a patient diagnosed with breast cancer, colorectal cancer, melanoma or lung cancer will benefit from or is predicted to be responsive to treatment with an individual therapeutic agent or a specific combination of therapeutic agents. These methods are based on screening a patient's solid tumors and detecting alterations in target nucleic acid sequences corresponding to a specific set of cancer-related genes. Kits for use in practicing the methods are also provided.

Abstract: A splice variant of bcr-abl mRNA that produces BCR-ABL protein with a truncated C-terminus and its role in resistance to treatment with kinase inhibitors is disclosed. Vectors for expressing the truncated gene product are provided as well as recombinant cells that express the truncated gene product from a cDNA construct. Also provided are methods compositions and kits for detecting the BCR-ABL splice variant. Additionally, methods for screening BCR-ABL kinase domain inhibitors which rely on the recombinant cells and methods of predicting likelihood for resistance of a CML patient with a BCR/ABL translocation respond to treatment with one or more BCR-ABL kinase inhibitors are also disclosed.
Abstract: Provided herein are methods for miRNA profiling for the diagnosis, prognosis, and management of melanoma and differentiation of melanoma from nevi.

Abstract: Methods are provided for detecting the amount of one or more HRT panel analytes (i.e., estrone (E1), estrone sulfate (E1s), 17?-estradiol (E2a), 17?-estradiol (E2b), estradiol sulfate (E2s), estriol (E3), equilin (EQ), 17?-dihydroequilin (EQa), 17?-dihydroequilin (EQb), Equilenin (EN), 17?-dihydroequilenin (ENa), 17?-dihydroequilenin (ENb), and ?8,9-dehydroestrone (dE1)) in a sample by mass spectrometry. The methods generally involve ionizing one or more HRT panel analytes in a sample and quantifying the generated ions to determine the amount of one or more HRT panel analytes in the sample. In methods where amounts of multiple HRT panel analytes are detected, the amounts of multiple analytes are detected in the same sample injection.
Abstract: The invention relates to the detection of methylmalonic acid (MMA). In a particular aspect, the invention relates to methods for detecting derivatized methylmalonic acid (MMA) by mass spectrometry.
Abstract: The invention provides methods for isolating RNA from whole urine and urine fractions for the diagnosis of prostate cancer and/or benign prostate hyperplasia. An exemplary method for diagnosing prostate cancer in an individual, said method comprises: (a) determining the amount of RNA encoding one or more diagnostic genes in the soluble urine fraction of a urine sample obtained from said individual; (b) comparing the amount of said RNA to a reference value for said one or more diagnostic genes, wherein said reference value is derived from the amount of RNA encoding said one or more diagnostic genes in one or more individuals that do not have prostate cancer; and (c) diagnosing said individual as having prostate cancer when the amount of said RNA is greater than said reference value.

Abstract: The present solution describes an automated system for analyzing analytical gels or blots, such as electrophoresis gels. The system can automatically detect the lanes within the gel and convert the lane into a feature vector that can be compared to reference datasets. Based on a comparison of the feature vector to the reference datasets, the system can automatically classify the feature vector (and the test sample in the lane) into a phenotype group.
