Summary for Patent: 9,315,870
Title:Method for detecting methylation of colorectal cancer specific methylation marker gene for colorectal cancer diagnosis
Abstract: The present invention relates to a method for detecting methylation of the bowel-cancer-specific methylation marker GPM6A (NM_201591, glycoprotein M6A) gene in order to diagnose bowel cancer, and more specifically relates to a method for providing information for diagnosing bowel cancer by detecting the methylation of a bowel-cancer-specific marker gene that is specifically methylated in bowel cancer cells. The method for detecting methylation and a diagnostic composition, kit and nucleic-acid chip according to the present invention can be used to advantage in diagnosing bowel cancer more accurately and quickly than by normal methods as they permit bowel cancer to be diagnosed at the initial genetic transformation step and so allow early diagnosis.

Application Number:13/994,732
Patent Claims:1. A method for detecting CpG methylation of GPM6A (glycoprotein M6A) gene, the method comprising the steps of: (a) isolating genomic DNA from a clinical sample of a human subject selected from the group consisting of colorectal tissue, feces, urine, serum, and blood plasma; (b) treating the genomic DNA or a fragment thereof with bisulfite, wherein the genomic DNA or fragment thereof is treated with bisulfite in such a way that cytosine is converted into a base that is different in its base-pairing behavior in the DNA duplex; and (c) determining hypermethylation of the CpG of the promoter or the CpG of the first intron of GPM6A gene in the genomic DNA or fragment thereof treated with bisulfite according to step (b) with primers selected from the group consisting of SEQ ID NOS: 16 to 19.

2. The method of claim 1, wherein the detection of hypermethylation is performed by a method selected from the group consisting of PCR, methylation-specific PCR, real-time methylation-specific PCR, PCR assay using a methylation DNA-specific binding protein, quantitative PCR, DNA chip-based assay, pyrosequencing, and bisulfite sequencing.

3. The method of claim 1, wherein step (c) is performed by detecting the hypermethylation of the CpG island of the promoter of GPM6A.

4. The method of claim 1, wherein the clinical sample is colorectal tissue.

5. The method of claim 1, wherein the clinical sample is feces.

6. The method of claim 1, wherein the clinical sample is urine.

7. The method of claim 1, wherein the clinical sample is serum.

8. The method of claim 1, wherein the clinical sample is blood plasma.

9. The method of claim 1, wherein step (c) is performed by detecting the hypermethylation of the CpG island of the first intron of GPM6A.

10. The method of claim 9, wherein the first intron of GPM6A gene is SEQ ID NO: 1.
