  • Publication number: 20210293823
    Abstract: The present application relates to a method for diagnosis of endometriosis in a subject, comprising the steps of (i) determining the level of ?2-Microglobulin protein (?2M) as a biomarker in a sample of said subject to be diagnosed; (ii) comparing the biomarker level as determined in steps (i) to a respective control level derived from one or more subject without endometriosis; wherein a reduced level as compared to the respective control level of ?2M is indicative for the presence of endometriosis in said subject to be diagnosed. In particular, the application relates to a diagnostic classifier comprising a combination of a plurality of biomarkers selected from the group consisting of ?2M protein level, CA19-9 level, CA125 protein level, PON-1 activity, MMP1 protein level and MMP2 protein level.

  • Patent number: 10731215
    Abstract: Aspects of the present invention relate to compositions and methods for providing DNA fragments from a remote sample. In particular aspects a remote sample comprising DNA is provided, DNA is isolated from the remote sample, and the isolated DNA is treated in a way which allows differentiation of methylated and unmethylated cytosine. Additional, particular embodiments provide compositions and methods for methylation analysis of DNA derived from a remote sample. Other aspects provide for compositions and methods of whole genome amplification of bisulfite treated DNA. Other aspects provide methods for determining the presence or absence of methylation of at least one cytosine, or a series of cytosines in cis, in human DNA of a blood sample, a plasma sample, a serum sample or a urine sample from a human individual.

  • Patent number: 9863001
    Abstract: The invention relates to a method for analyzing cytosine methylations in DNA sequences, according to which non-methylated cytosines are first converted into uracil while 5-methylcytosine remains unmodified. The DNA is then amplified by means of a polymerase and at least one primer whose 5 end is connected to a probe via a linker. The probe is intramolecularly hybridized onto the amplified products in accordance with the methylation state of the DNA, hybridization being detectable via different detection systems. The inventive method is particularly suitable for diagnosing and predicting cancer diseases and other diseases associated with a modification of the methylation state as well as for predicting undesired effects of medicaments.
