Abstract: Methods for extracting high quality nucleic acids from a heterogenous collection of nucleic acid-containing materials from a biological sample are disclosed. The heterogenous collection of nucleic-acid containing materials may contain cells or microvesicles, or both. The extractions obtained by the methods described herein are characterized by high yield and high integrity, making the extracted nucleic acids useful for various applications in which high quality nucleic acid extractions are preferred, e.g., a diagnosis, prognosis, or therapy evaluation for a medical condition.

Abstract: Methods are disclosed herein for assaying a biological sample or a bodily fluid obtained from a subject by isolating, obtaining or using a microvesicle fraction from the biological sample or bodily fluid and detecting in the microvesicle fraction the presence or absence of a genetic aberration in an IDH1, TDH2, TP53, PTEN, CDKN2A, NF1, EGFR, RB1, PIK3CA, or BRAF gene. The methods may be used for aiding the diagnosis, prognosis, monitoring, or therapy selection in relation to a disease or other medical condition (e.g., a glioma) in a subject.

Abstract: The present invention relates generally to the field of biomarker analysis, particularly determining gene expression signatures from urine samples. The disclosure provides compositions, kits and methods for diagnosing a prostate disorder such as prostate cancer in a male subject.

Abstract: Disclosed herein are methods for assaying a biological sample from a subject by analyzing components of microvesicle fractions in aid of risk, diagnosis, prognosis or monitoring of, or directing treatment of the subject for, a disease or other medical condition in the subject. Also disclosed are methods of treatment and identifying biomarkers using a microvesicle fraction of a subject. Kits, pharmaceutical compositions, and profiles related to the methods are also disclosed.

Abstract: The present invention features a novel EGFR variant, EGFRvVI, and methods for detecting the novel EGFR variant. The novel EGFR variant is preferentially expressed in some cancers. Methods for detecting EGFRvVI may aid in the diagnosis, prognosis, and therapeutic assessment of a subject.

Abstract: A method for extracting nucleic acids from a biological sample by isolating nucleic acid-containing particles from the biological sample by one or more centrifugation procedures, performing one or more steps to mitigate adverse factors that prevent or might prevent high quality nucleic acid extraction, and extracting nucleic acids from the isolated particles. The centrifugation procedures are performed at a speed not exceeding about 200,000 g. The extracted nucleic acids contain both 18S and 28S rRNA.

Abstract: The invention concerns gene signatures obtained from microvesicles and a method of applying these gene signatures in helping to determine a biological condition. The determination of a biological condition may aid, for example, the diagnosis, prognosis, and therapy treatment selection for disease in a subject.

Abstract: The invention provides novel methods for isolating microvesicles from a biological sample and for extracting nucleic acids from the microvesicles.

Abstract: Microvesicles are small membrane vesicles that either shed or bud off eukarotic cells. Analysis of the nucleic acid content of microvesicles may be useful in detecting the presence or absence of genetic aberrations. This invention discloses novel methods of diagnosing, prognosing, monitoring, or treating a disease, such as cancer, or other medical condition in a subject involving analyzing one or more nucleic acids contained within an isolated microvesicle for the presence or absence of one or more Kras genetic aberrations.

Abstract: The present invention discloses methods for diagnosing or prognosing a disease or medical condition in a subject by detecting the presence or absence of BRAF mutant nucleic acids from nucleic acids extracted from microvesicles from a biological sample. The present invention also discloses methods for assessing the responsiveness or determining a treatment regimen for a subject in need thereof by detecting the presence or absence of BRAF mutant nucleic acids from nucleic acids extracted from microvesicles from a biological sample. Methods for isolating microvesicles and extracting DNA and/or RNA from the microvesicles are also described.

Abstract: The invention provides a novel method for detecting the presence or absence of one or more transfer RNAs (tRNAs) contained in microvesicles from a subject. The invention also provides a novel method for detecting the presence or absence of one or more human endogenous retrovirus elements (HERV) in microvesicles from a subject. The methods disclosed is directed to aiding diagnosis, prognosis, minotring and evaluation of a disease or other medical condition in a subject.
