  • 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.

  • Patent number: 9983215
    Abstract: Methods and compositions are provided for diagnosing ectopic pregnancy in a mammalian subject by detecting changes in expression of the selected genes, gene fragments or transcripts or expression products, or changes in the expression levels of one or more of proteins or peptide fragments, identified in Table 2 and FIGS. 8 and 9 herein. A selected gene, gene transcript or protein/peptide expression product, or profiles or signatures formed by combinations of same, detected in a biological fluid, preferably sera, 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.

  • Patent number: 8338111
    Abstract: The present invention relates to methods for determining a risk or identifying a condition associated with the presence of endometriosis in a subject as well as testing a candidate compound for a therapeutic activity for the treatment of endometriosis and sorting patients based on the risk of having endometriosis. Specifically, the methods utilize novel markers for assessing the risk of the patient having endometriosis.
