  • Publication number: 20180238905
    Abstract: Methods and compositions are provided for diagnosing ectopic pregnancy in a mammalian subject by detecting changes in expression of ISM2, ADAM12, PST1, PSG7, PST11, PSG9, PSG2 and other genes identified therein, including combinations thereof. A selected gene, gene transcript or protein/peptide expression product, or profiles or signatures formed by combinations of same, detected in a biological fluid of a subject, enables comparison of the corresponding genes, proteins or profiles from that of a reference or control having a normal intrauterine pregnancy. Detection of characteristic changes in the gene profile or protein expression signature of the subject is correlated with a diagnosis of ectopic pregnancy. Various compositions for use in such diagnosis include PCR primer-probe sets or ligands, labeled or immobilized, which are capable of detecting the changes in expression or translation of these targets.

  • Publication number: 20140274794
    Abstract: Methods and compositions are provided for diagnosing ovarian cancer in a mammalian subject, preferably in a serum or plasma sample of a human subject. The methods and compositions enable the detection or measurement in the sample or from a protein level profile generated from the sample, the protein level of one or more specified biomarkers. Comparing the protein level(s) of the biomarker(s) in the subject's sample or from protein abundance profile of multiple biomarkers, with the level of the same biomarker(s) or profile in a reference standard, permits the determination of a diagnosis of ovarian cancer, or the identification of a risk of developing ovarian cancer, or enables the monitoring of the status of progression or remission of ovarian cancer in the subject followed during a therapeutic protocol.
