METHYLATED PROMOTERS AS BIOMARKERS OF COLON CANCER
First Claim
1. A method for diagnosing the presence of an abnormal condition in a subject suspected of having an abnormal condition, said method comprising a) determining a methylation status of at least one gene in the subject;
- and b) comparing the methylation status of said at least one gene in said subject to the normal methylation status of said at least one gene;
wherein a difference between the methylation status of said at least one gene in said subject and the normal methylation status of said at least one gene is indicative of the presence or absence or colon cancer in the subject, and wherein said at least one gene is tachykinin-1 (TAC1).

Abstract
The present invention provides methods for identifying or assessing probabilities for having or developing an abnormal condition in subject and for the recurrence of the abnormal condition in the subject after receiving treatment. The method comprises determining the methylation status of at least the tachykinin-1 (TAC1) gene in the subject and comparing this methylation status to normal methylation status. Differences between the methylation status of the TAC1 gene is indicative of the subject developing an abnormal condition or for the development or recurrence of the abnormal conditions after receiving treatment.

10. A method of monitoring the development of an abnormal condition in a subject, said method comprising
a) determining a methylation status of at least one gene in said subject at a first and second time point; - and
b) determining a difference between said methylation status at said first and second time points to assess a change of methylation status over time;
wherein said difference over time is indicative of a change in the subject'"'"'s probability of developing said abnormal condition, and wherein said at least one gene comprises tachykinin-1 (TAC1). - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A method for assessing the probability of a subject having an abnormal condition, said method comprising
a) determining a methylation status of at least one gene in gross normal tissue of the subject; - and
b) comparing the methylation status of said at least one gene in said subject to the normal methylation status of said at least one gene;
wherein a difference between the methylation status of said at least one gene in said gross normal tissue of said subject and the normal methylation status of said at least one gene indicates that the subject has an altered probability of having said abnormal condition, wherein said at least one gene is tachykinin-1 (TAC1).
