  • Patent number: 9169520
    Abstract: The present invention provides a novel cancer marker for evaluating the onset, the preclinical stage, the clinical stage, or the prognosis of a cancer in a subject, and an evaluation method using the same. A cancer marker containing at least one miRNA selected from hsa-miR-92 and hsa-miR-494 is used as a marker for cancers excluding breast cancer. A method for evaluating the possibility of cancers excluding breast cancer includes the step of detecting the expression level of a cancer marker in a biological sample collected from a subject. In this method, the cancer marker contains at least one miRNA selected from hsa-miR-92 and hsa-miR-494.

  • Patent number: 8828964
    Abstract: Disclosed is an identification marker which can be utilized for detection of various human cancer cells and whose expression closely relates to malignant alteration of cells, and compositions for human cancer treatment which are based on suppression of cancer cell proliferation through inhibition of expression of the identification marker. The marker is human heterochromatin protein 1? (HP1?), and the compositions for cancer treatment comprises one or more agents which suppresses the expression of human HP1? gene, such as siRNAs to human HP1?.

  • Publication number: 20130012412
    Abstract: An embodiment of the present invention provides a marker, a test method, and a test kit which can detect the onset of breast cancer that cannot be detected by palpation or mammography examination or breast cancer in an early stage (clinical stage 0), which are simple, and which have high reliability. A marker associated with breast cancer of an embodiment of the present invention is characterized by being a micro-RNA that is found in serum or plasma. More specifically, the marker contains at least a micro-RNA that is present in the serum or the plasma at a significantly reduced level after the onset of breast cancer, or during or after an early stage (during or after clinical stage 0) of breast cancer compared with that before the onset of breast cancer or before the early stage (before clinical stage 0) of breast cancer.

  • Patent number: 7776525
    Abstract: The expression level of a histamine-releasing factor (HRF) polynucleotide in a biological sample of a subject is measured and the HRF polynucleotide content is compared with that of a normal biological sample. An HRF polynucleotide expression level considerably higher than that of the normal biological sample is employed as an indication of a disease relating to endometriosis or a risk thereof.

  • Publication number: 20070184485
    Abstract: The level of a histamine-releasing factor (HRF) protein in a biological sample of a subject is measured and the HRF protein level is compared with that of a normal biological sample. A significantly higher HRF protein level compared with that of the normal biological sample is used as an indicator of a disease related to endometriosis or the degree of its risk.
