  • Publication number: 20240053363
    Abstract: An object of the present invention is to provide a biomarker that enables selection of an embryo having a high rate of implantation and pregnancy, that is, an embryo having high fertility, from embryos obtained through embryo culture after in vitro fertilization in infertility treatment, and a criterion therefor. Provided is a criterion that enables identification of an ovum suitable for implantation and pregnancy based on measurement of the concentration of soluble CD163 which is present in follicular fluid collected at the same time as an ovum in ovum pick up in infertility treatment, or which is present in serum immediately before the ovum pick up.

  • Publication number: 20230122642
    Abstract: An object of the present invention is to provide a method for detecting malignant ovarian tumor as distinguished from benign ovarian tumor, and a reagent that can be used for the method. Provided are a method for detecting malignant ovarian tumor (excluding high-grade serous carcinoma) as distinguished from benign ovarian tumor, characterized by measuring the amount of TFPI2 in a sample from a patient, and a reagent for detecting malignant ovarian tumor (excluding high-grade serous carcinoma) as distinguished from benign ovarian tumor contains an antibody that specifically recognizes TFPI2 processing polypeptide and intact TFPI2.

  • Patent number: 11193936
    Abstract: The present invention aims to provide a method for detecting, with high sensitivity and specificity, ovarian clear cell adenocarcinoma, which is highly malignant, among benign and malignant ovarian tumors having various tissue types, and a reagent that can be used for the method. The present invention provides NT-TFPI2, which is a novel processed tissue factor pathway inhibitor 2 polypeptide, as a new detection marker for ovarian clear cell adenocarcinoma. The detection of ovarian clear cell adenocarcinoma is carried out by measuring the amount of NT-TFPI2, or the total amount of NT-TFPI2 and intact TFPI2. The reagent for detecting ovarian clear cell adenocarcinoma contains an antibody that specifically recognizes NT-TFPI2 and intact TFPI2.

  • Publication number: 20160253454
    Abstract: According to the method of evaluating female genital cancer of the present invention, amino acid concentration data on concentration values of amino acids in blood collected from a subject to be evaluated is measured, and the state of female genital cancer including at least one of cervical cancer, endometrial cancer, and ovarian cancer in the subject is evaluated based on the concentration value of at least one of Thr, Ser, Asn, Gln, Pro, Gly, Ala, Cit, Val, Met, Ile, Leu, Tyr, Phe, His, Trp, Orn, Lys, and Arg contained in the measured amino acid concentration data of the subject.
