Abstract
Methods of prognosis and monitoring of breast cancer include determining the level of one or more of the markers comprising asymmetric dimethyl arginine (ADMA), beta-hydroxybutyrate (BHB) and microRNA-31 (miR-31) in patient samples. An increased level is correlated with poor prognosis. Breast cancer is treated by administration of one or more inhibitors of ADMA and/or BHB.
Claims10
A prognostic method for breast cancer in a subject comprising:
- (a) determining the level of at least one of the following in a test sample from a subject:
- (i) asymmetric dimethyl arginine;
- (ii) beta-hydroxybutyrate;
- and (iii) miR-31;
- and
- b) comparing the level of at least one of (i) asymmetric dimethyl arginine, (ii) beta-hydroxybutyrate, and (iii) miR-31 in said test sample to the level of in a control sample, wherein an elevated level of at least one of (i) asymmetric dimethyl arginine, (ii) beta-hydroxybutyrate, and (iii) miR-31 in said test sample relative to the level in said control sample is a prognostic indicator of the course of breast cancer disease in said subject.
A method of monitoring the progression of breast cancer in a subject, said method comprising:
- (a) obtaining a first sample from a subject at a first time point and a second sample from said subject at a second time point;
- (b) determining the level of at least one of the following in said first and second samples:
- (i) asymmetric dimethyl arginine;
- (ii) beta-hydroxybutyrate;
- and (iii) miR-31;
- and
- (c) comparing the level of said at least one of (i) asymmetric dimethyl arginine, (ii) beta-hydroxybutyrate, and (iii) miR-31 in said first sample to the level in said second sample, wherein an elevated level of at least one of (i) asymmetric dimethyl arginine, (ii) beta-hydroxybutyrate, and (iii) miR-31 in said second sample relative to the level in said first sample is an indication that the cancer has progressed in said subject.
A method for treating breast cancer comprising administering to a breast cancer patient in need of such treatment an effective amount of an inhibitor of asymmetric dimethyl arginine or an inhibitor of beta-hydroxybutyrate.
