  • METHOD FOR DETERMINING IF ORIGIN OF BIOLOGICAL SAMPLE IS FROM LIVER TISSUE
    Publication number: 20230257812
    Abstract: The present invention relates to a method for determining whether a biological sample of unknown origin is derived from liver tissue and a composition comprising a liver tissue-specific DNA methylation marker for performing the same, and the liver tissue-specific DNA methylation marker has a low methylation level in other tissue except for liver tissue and has a high methylation level in normal liver tissue and liver cancer tissue, and thus, it can determine whether a biological sample is derived from liver tissue with excellent accuracy.
    Type: Application

  • DNA METHYLATION MARKER FOR PREDICTING RECURRENCE OF LIVER CANCER, AND USE THEREOF
    Publication number: 20230109129
    Abstract: The present invention relates to a DNA methylation marker for predicting the recurrence of liver cancer by using the difference in the DNA methylation levels according to a liver cancer prognosis, and when the marker is used, the recurrence of liver cancer can be easily predicted, and a more personalized treatment for patients at high risk of liver cancer recurrence can be provided and clinical information for avoiding unnecessary over-treatment can be provided.

  • METHOD FOR ASSESSING PROGNOSIS OR RISK STRATIFICATION OF LIVER CANCER BY USING CPG METHYLATION VARIATION IN GENE
    Publication number: 20220259676
    Abstract: The present invention relates to a method for assessing the prognosis or risk stratification of liver cancer by using a clinical specimen mixed with a normal tissue, wherein at least one CpG site that shows a low methylation level in normal and blood tissues but a high methylation level in only a cancer tissue is measured for methylation level.

  • METHOD FOR DETERMINING WHETHER BIOLOGICAL SAMPLE HASORIGINATED FROM LIVER CANCER TISSUE
    Publication number: 20220228224
    Abstract: The present invention relates to a method for determining whether a biological sample of unknown origin is derived from liver cancer tissue and a composition comprising a liver cancer tissue-specific DNA methylation marker for performing the same, and the liver cancer tissue-specific DNA methylation marker has a low methylation level in normal liver tissue and other tissue, and has a high methylation level only in liver cancer tissue, and thus, it can determine whether a biological sample is derived from liver cancer tissue with excellent accuracy.
